Start-up<br />

Start-up operations<br />

Procedure<br />

These operations must be carried out<br />

before using a device for the first time.<br />

A general check of the device takes only a few minutes and avoids any risk of<br />

mistakes due <strong>to</strong> errors or negligence.<br />

A general check must be carried out:<br />

b prior <strong>to</strong> initial use<br />

b following an extended period during which the device is not used.<br />

A check must be carried out with the entire switchboard de-energised.<br />

In switchboards with compartments, only those compartments that may be<br />

accessed by the opera<strong>to</strong>rs must be de-energised.<br />

<strong>Electric</strong>al tests<br />

Insulation and dielectric-withstand tests must be carried out immediately after<br />

delivery of the switchboard. These tests are precisely defined by international<br />

standards and must be directed and carried out by a qualified expert.<br />

Prior <strong>to</strong> running the tests, it is absolutely necessary <strong>to</strong>:<br />

b disconnect all the electrical auxiliaries of the device (MCH, MX, MN)<br />

b remove the long-time rating plug on the 7.0 A control units.<br />

Removal of the rating plug disconnects the voltage measurement input.<br />

Switchboard inspection<br />

Check that the devices are installed in a clean environment, free of any installation<br />

scrap or items (<strong>to</strong>ols, electrical wires, broken parts or shreds, metal objects, etc.).<br />

Conformity with the installation diagram<br />

Check that the devices conform with the installation diagram:<br />

b breaking capacities indicated on the rating plates<br />

b identification of the control unit (type, rating)<br />

b presence of any optional functions (mo<strong>to</strong>r mechanism)<br />

b protection settings (long time, short time, instantaneous, ground fault)<br />

b identification of the protected circuit marked on the front of each device.<br />

Condition of connections and auxiliaries<br />

Check device mounting in the switchboard and the tightness of power connections.<br />

Check that all auxiliaries and accessories are correctly installed:<br />

b electrical auxiliaries<br />

b terminal blocks<br />

b connections of auxiliary circuits.<br />

Operation<br />

Check the mechanical operation of the devices:<br />

b opening of contacts<br />

b closing of contacts.<br />

Check on the control unit<br />

Check the control unit of each circuit breaker using the respective user manuals.<br />

What <strong>to</strong> do when the circuit<br />

breaker trips?<br />

Note the fault<br />

Faults are signalled locally and remotely by the indica<strong>to</strong>rs and auxiliary contacts<br />

installed on devices (depending on each configuration). See page 32 in this manual<br />

and the user manual of the control unit for information on the fault indications<br />

available with your circuit breaker.<br />

Identify the cause of tripping<br />

A circuit must never be reclosed (locally or remotely) before the cause of the fault<br />

has been identified and cleared.<br />

Depending on the type of fault and the criticality of the loads, a number of<br />

precautionary measures must be taken, in particular the insulation and dielectric<br />

tests on a part of or the entire installation. These checks and test must be directed<br />

and carried out by qualified personnel.<br />

Inspect the circuit breaker following a short-circuit<br />

b check the tightness of connections (see the device installation manual)<br />

b check the disconnecting-contact clusters.<br />

Reset the circuit breaker<br />

The circuit breaker can be reset locally or remotely. See pages 5, 9 and 15<br />

in this manual for information on how the device can be reset.<br />

Ambient temperature<br />

Compact devices can operate under the following temperature conditions:<br />

b the electrical and mechanical characteristics are stipulated for an ambient<br />

temperature of -5° C <strong>to</strong> +70° C<br />

b circuit-breaker closing is guaranteed down <strong>to</strong> -35° C<br />

b Compact (without the control unit) can be s<strong>to</strong>red in an ambient temperature<br />

of -40° C <strong>to</strong> +85° C<br />

b the control unit can be s<strong>to</strong>red in an ambient temperature of -25° C <strong>to</strong> +85° C.<br />

Extreme atmospheric conditions<br />

Compact devices have successfully passed the tests defined by the following<br />

standards for extreme atmospheric conditions:<br />

b IEC 68-2-1: dry cold at -55° C<br />

b IEC 68-2-2: dry heat at +85° C<br />

b IEC 68-2-30: damp heat (temperature +55° C, relative humidity 95%)<br />

b IEC 68-2-52 level 2: salt mist.<br />

Compact devices can operate in the industrial environments defined by standard<br />

IEC 947 (pollution degree up <strong>to</strong> 3).<br />

It is nonetheless advised <strong>to</strong> check that the devices are installed in suitably cooled<br />

switchboards without excessive dust.<br />

Vibrations<br />

Compact devices resist electromagnetic or mechanical vibrations.<br />

Tests are carried out in compliance with standard IEC 68-2-6 for the levels required<br />

by merchant-marine inspection organisations (Veritas, Lloyd's, etc.):<br />

b 2 <strong>to</strong> 13.2 Hz: amplitude ±1 mm<br />

b 13.2 <strong>to</strong> 100 Hz: constant acceleration 0.7 g.<br />

Excessive vibration may cause tripping, breaks in connections or damage <strong>to</strong><br />

mechanical parts.<br />

b IEC 947-2, appendix F<br />

b IEC 947-2, appendix B (trip units with earth-leakage function).<br />

The above tests guarantee that:<br />

b no nuisance tripping occurs<br />

b tripping times are respected.<br />
