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 />

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 />
