4 Overview



INSTALLATION 

1. General Installation Notes 

In order to enhance the reliability of the dimmers, it is recommended that they are operated within the following 

environmental limits: 

• Temperature: 18°C - 25° C 

• Relative Humidity: 60% - 80% 

• Condensation level: Zero 

The dimmers may emit a slight buzzing noise during operation. They should be installed away from areas where such 

noise would be undesirable. 

Refer to "Specifications" on page 18 for complete technical specifications for each Propack Dimmer model. 

2. Installing 120v Models (75332 / 75333) 

WARNING! Hazardous voltages are present in Propack Dimmers. Ensure that the mains supply is isolated before 

opening the equipment for installation or servicing. Propack Dimmers should be installed and serviced by qualified 

personnel only. Propack Dimmers may be mounted together in a rack (for hire or touring purposes). 

Mains Power Input Connections (120v) 

When installing Propack 120v Dimmers, use the following precautions and guidelines: 

• Propack 120v Dimmers require a nominal mains input at 120V 60Hz AC. This supply must be three-phase. Separate 

Neutral and Ground conductors are required. 

• Propack Dimmers must be Grounded. 

• The Neutral conductor must have the same (or greater) cross-sectional area as the Phase conductor(s). (SCR dimmers 

operate using ‘phase control’. This renders the ‘balancing’ of loads across phases - and thus a reduction in 

Neutral currents impossible.) 

• Propack Dimmers should be connected to their mains supplies via adequately rated cable, together with any associated 

plug and socket connectors. For full power operation, the supply must be rated at 80A for three-phase operation. 

These ratings may be reduced if the supply protective devices are selected to limit the current drawn to 

appropriate limits. Should supply diversity be applied, care is required in the sizing of supply neutral conductors. If 

in doubt, please seek advice from your Strand Lighting representative. 

• For safety in operation, each unit must be fed from an appropriately fused supply. 

• It is strongly recommended that the mains supply to the Propack Dimmer is taken via a local circuit breaker, so that 

the supply may be easily disconnected for plugging and unplugging of load connectors and for service or maintenance. 

• All cables, switch gear and protection equipment must be selected and installed in accordance with local electrical 

regulations. 

General Installation Notes 5



Mains Cable Entry (120v) 

The mains input cable will enter the unit via the rear connection panel. 

To remove rear connection panel: 

Step 1. At rear of unit, remove four screws (Figure 1). 

Step 2. Punch a single hole to accept appropriate cables and strain relief for your installation. 

Mains Cable Termination (120v) 

Figure 1: Rear Cable Entry Panel 

The mains input is connected at a set of screw terminal blocks located inside the unit (at the right-hand side, looking 

from the front of the unit). The terminals will accept cables of up to #6 AWG in size. 

WARNING! Always connect Ground and Neutral first. 

To terminate mains cable: 

Step 1. Loosen all three phase terminals, Neutral and Ground (Figure 2). 

Step 2. Place incoming cable inside terminals and tighten securely. 

Protection (120v) 

Figure 2: Three-Phase Operation at 80A Per Phase 

The mains supply to each Propack Dimmer must be protected against external overload. Appropriate circuit breaker 

ratings should not exceed 80 Amps for a three-phase supply. If the available mains supply is not capable of providing 

the full rated currents, the protection device rating must be reduced accordingly; it will not be possible to use the 

dimmers with their maximum rated loads. 

Protection systems on the supply to each unit should limit the potential fault current level to 10,000AIC or less. 

6 Installation



Power Distribution (120v) 

To achieve correct grounding and mains power distribution, it is recommended that all dimmers and lighting control 

equipment within the installation draw mains power from one central distribution point. This should be as close as 

possible to the mains power intake for the site or building. The wiring from the distribution point to the lighting 

equipment should ideally be used for supplying power to the lighting equipment alone, and not to other appliances or 

equipment. 

WARNING! Propack Dimmers must be properly Grounded, both for safety and to ensure correct operation. 

It is essential that all Ground connections within the overall installation are at comparable potentials. If this is not the 

case, circulating currents may be generated in signal earth connections, possibly leading to fluctuating light levels and 

(in some extreme cases) damage to wiring or equipment. If in doubt as to the nature of your local electrical supply 

arrangements, please seek advice from a Strand Lighting representative or an electrical contractor. 

Rack Mounting (120v) 

The Propack Dimmer is designed for rack mounting. Care should be taken to mount the unit securely in an equipment 

rack designed to hold equipment of this type. 

To prevent overheating of rack-mounted dimmers when in use, a fan - or set of fans - should be fitted to the top of the 

equipment rack, such that air is extracted upwards. To ensure adequate cooling, the fan(s) should provide an airflow 

of about 16 liters per second across the top of each unit. 

A gap of 1U (1.75 inches / 44.45 mm) is required between adjacent pairs of dimmer racks. Leave a rear ventilation 

clearance of 4 inches. Due to the weight of the unit, rack side supports are recommended, but care must be taken to 

ensure that these do not obstruct ventilation. 

CAUTION: Additional forced ventilation may be advised if racks are mounted within a flight case or similar closely 

constraining enclosure. 

Installing 120v Models (75332 / 75333) 7



3. Installing 230v Model (75322) 

WARNING! Hazardous voltages are present in Propack Dimmers. Ensure that the mains supply is isolated before 

opening the equipment for installation or servicing. Propack Dimmers should be installed and serviced by qualified 

personnel only. Propack Dimmers may be mounted together in a rack (for hire or touring purposes). 

Mains Power Input Connections (230v) 

When installing Propack 230v Dimmers, use the following precautions and guidelines: 

• Propack 230v Dimmers require a nominal mains input at 230V 50Hz AC. This supply may be either single or 

three-phase (star only), depending on the method of connection. In either case, separate Neutral and Earth conductors 

are required. 

• Propack Dimmers must be Earthed. 

• Propack Dimmers are designed such that Earth leakage currents are minimized, allowing their use on mains power 

supplies protected by 30mA Residual Current Devices. However, utilizing RCD protection in dimming installations 

may present problems. For specific advice please contact your Strand Lighting representative. 

• The Neutral conductor must have the same (or greater) cross-sectional area as the Phase conductor(s). (Triac and 

thyristor dimmers operate using ‘phase control’. This renders the ‘balancing’ of loads across phases - and thus a 

reduction in Neutral currents impossible.) 

• Propack Dimmers should be connected to their mains supplies via adequately rated cable, together with any associated 

plug and socket connectors. For full power operation, the supply must be rated at 125A for single phase 

operation, 63A for three-phase operation. These ratings may be reduced if the supply protective devices are 

selected to limit the current drawn to appropriate limits. Should supply diversity be applied, care is required in the 

sizing of supply Neutral conductors. If in doubt, please seek advice from your Strand Lighting representative. 

• For safety in operation, each unit must be fed from an appropriately fused supply. 

• It is strongly recommended that the mains supply to the Propack Dimmer is taken via a local isolating switch, so 

that the supply may be easily disconnected for plugging and unplugging of load connectors and for service or 

maintenance. 

• All cables, switch gear and protection equipment must be selected and installed in accordance with local electrical 

regulations. 

Mains Cable Entry (230v) 

The mains input cable will enter the unit via the rear connection panel. 

To remove rear connection panel: 

Step 1. At rear of unit, remove four screws (Figure 3). 

Step 2. Punch a single hole to accept appropriate cables and strain relief for your installation. 

Figure 3: Rear Cable Entry Panel 

8 Installation



Mains Cable Termination (230v) 

The mains input is connected at a set of screw terminal blocks located inside the unit (at the right-hand side, looking 

from the front of the unit). The terminals will accept cables of up to 16 mm2 in size. If it is required to connect a 

Propack Dimmer to a single phase supply, the link bar supplied with the unit should be used to join the three-phase 

terminals together as shown in the figure below. 

WARNING! Do NOT fit the link bar when the unit is connected to a three-phase supply. 

To terminate mains cable: 

Step 1. Loosen all three phase terminals. 

Step 2. Place incoming cable inside terminals and tighten securely. 

Figure 4: Three-Phase Operation at 80A per phase 

Protection (230v) 

Figure 5: Single Phase Operation 230v 

The mains supply to each Propack Dimmer must be protected against external overload. Appropriate fuse or circuit 

breaker ratings are 63A for a three-phase supply. If the available mains supply is not capable of providing the full 

rated currents, the protection device rating must be reduced accordingly; it will not be possible to use the dimmers 

with their maximum rated loads. 

Protection systems on the supply to each unit should limit the potential fault current level to 1500A or less. 

Installing 230v Model (75322) 9



Power Distribution (230v) 

To achieve correct Earthing and mains power distribution, it is recommended that all dimmers and lighting control 

equipment within the installation draw mains power from one central distribution point. This should be as close as 

possible to the mains power intake for the site or building. The wiring from the distribution point to the lighting 

equipment should ideally be used for supplying power to the lighting equipment alone, and not to other appliances or 

equipment. 

WARNING! Propack Dimmers must be properly Earthed, both for safety and to ensure correct operation. 

It is essential that all Earth connections within the overall installation are at comparable potentials. If this is not the 

case, circulating currents may be generated in signal earth connections, possibly leading to fluctuating light levels and 

(in some extreme cases) damage to wiring or equipment. 

Care should be taken when differing electrical supplies (for example local generation for dimmers, public mains for 

control console) are in use or internal mains power distribution is TN-C (combined neutral & earth conductors). If in 

doubt as to the nature of your local electrical supply arrangements, please seek advice from a Strand Lighting 

representative or an electrical contractor. 

Rack Mounting (230v) 

The Propack Dimmer is designed for rack mounting. Care should be taken to mount the unit securely in an equipment 

rack designed to hold equipment of this type. 

To prevent overheating of rack-mounted dimmers when in use, a fan - or set of fans - should be fitted to the top of the 

equipment rack, such that air is extracted upwards. To ensure adequate cooling, the fan(s) should provide an airflow 

of about 16 liters per second across the top of each unit. 

A gap of 1U (44.5mm) is required between adjacent pairs of dimmer racks. Leave a rear ventilation clearance of 

100mm. Due to the weight of the unit, rack side supports are recommended, but care must be taken to ensure that 

these do not obstruct ventilation. 

CAUTION: Additional forced ventilation may be advised if racks are mounted within a flight case or similar closely 

constraining enclosure. 

10 Installation



INPUT/OUTPUT 

1. Control Input 

Propack Dimmers accept DMX512 control inputs. 

DMX512 

The DMX512 input will accept a multiplexed digital control signal which conforms to USITT specification DMX512 

(1990). Details of this specification are available from USITT. 

The DMX512 control input is via a five-pin male XLR type connector. Pin connections are shown in Figure 6 below. 

A five-pin female XLR connector is also fitted to allow a series of Propack Dimmers (or other DMX512 equipment) 

to be daisy-chained together.

2. Dimmer Outputs 

Dimmer output connections are by means of receptacle/socket outlets located at the rear panel of the Propack 

Dimmer. 

Guidelines: 

• When operating from a three-phase supply, dimmers 1, 2, 3 & 4 are connected to phase 1, dimmers 5, 6, 7 & 8 to 

phase 2, and dimmers 9, 10, 11 & 12 to phase 3. 

• Plugs and connectors used for dimmer output connections must be of the correct type to match the socket outlets. 

• It is important that plugs are wired correctly. Figure 7 shows the various types of socket outlets fitted to Propack 

Dimmers.

MAINTENANCE AND TESTING 

1. Overview 

Propack Dimmers do not require routine maintenance other than external cleaning. However, in common with all 

electrical equipment, they should be periodically checked to ensure that they remain in good condition. Any repairs or 

maintenance to the internal electronics or other circuitry should be carried out only by authorized Strand Lighting 

Service Personnel or approved Service Providers. 

2. Safety Tests 

Propack Dimmers are subjected to safety inspections and tests prior to shipment from the Strand Lighting factory. 

If, as part of routine maintenance, the units are to be subjected to electrical safety tests applied using a standard 

Portable Appliance Tester, the following points should be observed: 

• The nature of the electronic dimmer circuits means that an "insulation test" using a voltage in the order of 500V 

will give a result of approximately 1.7MO. Although this may appear as a test failure, the apparently low resistance 

is normal for these units and is not due to failing insulation. User safety is not at risk. 

CAUTION: A high voltage "Flash" test must not be applied to a Propack dimmer pack. 

CAUTION: A high current Earth/Ground continuity test must not be applied to the signal ground pins of the control 

input connector(s).
