Wiring of control auxiliaries
Under pick-up conditions, the level of consumption is approximately 150 to 200 VA.
Consequently, for low supply voltages (12, 24, 48 V), cables must not exceed a
maximum length determined by the supply voltage and the cross-section
of the cables.

Start-up
Start-up operations
Procedure
These operations must be carried out
before using a device for the first time.
A general check of the device takes only a few minutes and avoids any risk of
mistakes due to errors or negligence.
A general check must be carried out:
c prior to initial use
c following an extended period during which the device is not used.
A check must be carried out with the entire switchboard de-energised.
In switchboards with compartments, only those compartments that may be
accessed by the operators must be de-energised.
Electrical tests
Insulation and dielectric-withstand tests must be carried out immediately after
delivery of the switchboard. These tests are precisely defined by international
standards and must be directed and carried out by a qualified expert.
Prior to running the tests, it is absolutely necessary to:
c disconnect all the electrical auxiliaries of the device (MCH, MX, MN)
c remove the long-time rating plug on the 7.0 A control units.
Removal of the rating plug disconnects the voltage measurement input.
Switchboard inspection
Check that the devices are installed in a clean environment, free of any installation
scrap or items (tools, electrical wires, broken parts or shreds, metal objects, etc.).
Conformity with the installation diagram
Check that the devices conform with the installation diagram:
c breaking capacities indicated on the rating plates
c identification of the control unit (type, rating)
c presence of any optional functions (motor mechanism)
c protection settings (long time, short time, instantaneous, ground fault)
c identification of the protected circuit marked on the front of each device.
Condition of connections and auxiliaries
Check device mounting in the switchboard and the tightness of power connections.
Check that all auxiliaries and accessories are correctly installed:
c electrical auxiliaries
c terminal blocks
c connections of auxiliary circuits.
Operation
Check the mechanical operation of the devices:
c opening of contacts
c closing of contacts.
Check on the control unit
Check the control unit of each circuit breaker using the respective user manuals.

What to do when the circuit
breaker trips?
Note the fault
Faults are signalled locally and remotely by the indicators and auxiliary contacts
installed on devices (depending on each configuration). See page 32 in this manual
and the user manual of the control unit for information on the fault indications
available with your circuit breaker.
Identify the cause of tripping
A circuit must never be reclosed (locally or remotely) before the cause of the fault
has been identified and cleared.
Depending on the type of fault and the criticality of the loads, a number of
precautionary measures must be taken, in particular the insulation and dielectric
tests on a part of or the entire installation. These checks and test must be directed
and carried out by qualified personnel.
Inspect the circuit breaker following a short-circuit
c check the tightness of connections (see the device installation manual)
c check the disconnecting-contact clusters.
Reset the circuit breaker
The circuit breaker can be reset locally or remotely. See pages 5, 9 and 15
in this manual for information on how the device can be reset.

Compact operating
conditions
Ambient temperature
Compact devices can operate under the following temperature conditions:
c the electrical and mechanical characteristics are stipulated for an ambient
temperature of -5° C to +70° C
c circuit-breaker closing is guaranteed down to -35° C
c Compact (without the control unit) can be stored in an ambient temperature
of -40° C to +85° C
c the control unit can be stored in an ambient temperature of -25° C to +85° C.

Compact devices have successfully passed the tests defined by the following
standards for extreme atmospheric conditions:
c IEC 68-2-1: dry cold at -55° C
c IEC 68-2-2: dry heat at +85° C
c IEC 68-2-30: damp heat (temperature +55° C, relative humidity 95%)
c IEC 68-2-52 level 2: salt mist.
Compact devices can operate in the industrial environments defined by standard
IEC 947 (pollution degree up to 3).
E60418A
It is nonetheless advised to check that the devices are installed in suitably cooled
switchboards without excessive dust.
Vibrations
Compact devices resist electromagnetic or mechanical vibrations.
Tests are carried out in compliance with standard IEC 68-2-6 for the levels required
by merchant-marine inspection organisations (Veritas, Lloyd's, etc.):
c 2 to 13.2 Hz: amplitude ±1 mm
c 13.2 to 100 Hz: constant acceleration 0.7 g.

Excessive vibration may cause tripping, breaks in connections or damage to

Electromagnetic disturbances
Compact devices are protected against:
v overvoltages caused by devices that generate electromagnetic disturbances
v overvoltages caused by an atmospheric disturbance or by a distribution-system
outage (e.g. failure of a lighting system)
v devices emitting radio waves (radios, walkie-talkies, radar, etc.)
v electrostatic discharges produced by users.

trip
Compact devices have successfully passed the electromagnetic-compatibility tests
(EMC) defined by the following international standards:
c IEC 947-2, appendix F
c IEC 947-2, appendix B (trip units with earth-leakage function).
The above tests guarantee that:
c no nuisance tripping occurs
c tripping times are respected.
Cleaning
v non-metallic parts:
never use solvent, soap or any other cleaning product. Clean with a dry cloth only
v metal parts:
clean with a dry cloth whenever possible. If solvent, soap or any other cleaning
product must be used, make sure that it does not come into contact with
non-metallic parts.
