Power supply unit UPS 60, Or<strong>de</strong>r No. 77 3400 10<br />
The power supply unit UPS 60 is a power supply unit and inclu<strong>de</strong>s the electronics that builds up an<br />
uninterrupted power supply (UPS) in combination with battery set for UPS 60 (or<strong>de</strong>r no. 77 3450 00).<br />
Input voltage of 115 - 230 V AC is transformed into 24 V DC output voltage. The UPS feature ensures<br />
the supply of the connected DC users also in case of a mains power failure.<br />
If the mains input voltage fails or when it drops to less than 90 VAC, the two connected lead batteries<br />
will continue to supply the users without any interruption.<br />
To protect the batteries from going flat, circuit breakers will open when during the UPS mo<strong>de</strong> the<br />
output voltage drops below to 19.5 V. When the mains supply voltage is active again, the system<br />
reverts to its normal operating mo<strong>de</strong>.<br />
Roughly every 15 minutes, an integrated test circuitry performs a voltage check at the battery<br />
terminals, the connections and at the circuit breakers. Upon the return of the mains supply current, the<br />
battery is isolated from the outputs, and the internal charging module recharges the battery.<br />
Safety instructions<br />
• Non-compliance with the safety instruction or improper handling of the unit (e.g. skin<br />
contact with live components when the unit is open) can be extremely dangerous.<br />
• The power supply unit UPS 60 should only be installed and commissioned by<br />
qualified specialists.<br />
• Before effecting any work at or with the unit, it must be isolated from any voltage<br />
(mains or battery).<br />
• Connection to the mains supply must be executed acc. to the valid national<br />
regulations (for Germany: VDE 0100 and VDE 0160).<br />
• Fuse or circuit breaker must be provi<strong>de</strong>d for safe isolation from the input (mains)<br />
current.<br />
• Overheating of the unit may occur when the values as shown in the technical data<br />
are excee<strong>de</strong>d. This may lead to permanent damage to the unit, and system safety is<br />
jeopardised.<br />
• Always watch for the safe isolation of AC and DC circuits!<br />
• Observe the general safety instructions for the handling of batteries! Sufficient<br />
ventilation must be provi<strong>de</strong>d to preclu<strong>de</strong> the <strong>de</strong>velopment of an explosive hydrogenair<br />
mixture!<br />
• If the power supply unit UPS 60 will not be used for a longer time, first the batteries<br />
have to be fully charged. After that the power supply unit UPS 60 has to be<br />
disconnected from the mains supply. Furthermore the battery connection cable must<br />
be disconnected from the battery set for UPS 60 (see chapter 2.1). Alternatively the<br />
battery fuse in the battery set for UPS 60 can be removed.<br />
1. Mounting<br />
The power supply unit UPS 60 is <strong>de</strong>signed for wall mounting. Bore holes are prepared at the housing<br />
for fixing the unit at the wall using the enclosed mounting material. A dimensional drawing is shown on<br />
the next page.<br />
Before mounting, check the condition of the wall itself.<br />
The power supply unit UPS 60 weighs approx. 4 kg.<br />
The unit must be mounted such that the venting ports are at the top and bottom.<br />
The selected location must ensure sufficient air circulation above and below the unit. Therefore, check<br />
for minimum distance of 50 mm to walls, ceiling and other equipment. The venting ports must not be<br />
covered up. Insufficient air circulation may lead to damage to the power supply unit.<br />
