The charge status is indicated as follows. The springs in the circuit breaker operating mechanism must be charged to store the energy required to close the main contacts. The springs may be charged manually using the charging handle or automatically by the optional MCH gear motor.

Manual charging.Pull the handle down six times until you hear a "clack".

Automatic charging.If the MCH gear motor is installed, the spring is automatically recharged after each closing.

Using EasyPact Closing the circuit breaker

Closing conditionsClosing (i.e. turning the circuit ON) is possible only if the circuit breaker is "ready to close". The prerequisites are the following:

b device open (OFF) b springs charged b no opening order present.

The circuit breaker will not close unless it is "ready to close" when the order is given.

Closing the circuit breakerLocally (mechanical)Press the mechanical ON pushbutton.

Remotely

Anti-pumping functionThe purpose of the mechanical anti-pumping function is to ensure that a circuit breaker receiving simultaneous opening and closing orders does not open and close indefinitely. If there is a continuous closing order, after opening the circuit breaker remains open until the closing order is discontinued. A new closing order is required to close the circuit breaker. A new order is not required if the closing release is wired in series with the PF "ready to close" contact.

When connected to a remote control panel, the XF closing release can be used to close the circuit breaker remotely.

Inspecting and testing before use

Initial testsProcedure

A general check of the circuit breaker takes only a few minutes and avoids any risk of mistakes due to errors or negligence.A general check must be carried out:

b prior to initial use b following an extended period during which the circuit breaker 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 testsInsulation 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: b disconnect all the electrical auxiliaries of the circuit breaker (MCH, MX, XF, MN) b remove the long-time rating plug on the 2.0, 6G control units. Removal of the

rating plug disconnects the voltage measurement input.

Switchboard inspectionCheck that the circuit breakers 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 diagramCheck that the devices conform with the installation diagram:

b breaking capacities indicated on the rating plates b identification of the control unit (type, rating) b presence of any optional functions (remote ON/OFF with motor mechanism,

auxiliaries, measurement and indication modules, etc.) b protection settings (long time, short time, instantaneous, earth fault) b identification of the protected circuit marked on the front of each circuit breaker.

Condition of connections and auxiliariesCheck device mounting in the switchboard and the tightness of power connections.Check that all auxiliaries and accessories are correctly installed:

b electrical auxiliaries b terminal blocks b connections of auxiliary circuits.

OperationCheck the mechanical operation of the circuit breakers:

b opening of contacts b closing of contacts.

Check on the control unitCheck the control unit of each circuit breaker using the respective user manuals.

These operations must be carried out in particular before using a Easypact device for the first time.

3751201116AA - 03/2013HRB75971 - 03/2013

Note the faultFaults are signalled locally and remotely by the indicators and auxiliary contacts installed on circuit breakers (depending on each configuration). See page 12 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 trippingA circuit must never be reclosed (locally or remotely) before the cause of the fault has been identified and cleared.A fault may have a number of causes:

b depending on the type of control unit, fault diagnostics are available. See the user manual for the control unit.

b 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 b Check the arc chutes (see page 40) b Check the contacts (see page 40) b Check the tightness of connections (see the device installation manual) b Check the disconnecting-contact clusters (see page 40).

Reset the circuit breakerThe circuit breaker can be reset locally or remotely. See page 12 in this manual for information on how the circuit breaker can be reset.

Easypace SPS devices can operate under the following temperature conditions: b the electrical and mechanical characteristics are stipulated for an ambient

temperature of -5 °C to +70 °C b circuit-breaker closing is guaranteed down to -35 °C b the control unit can be stored in an ambient temperature of -25 °C to +85 °C

Extreme atmospheric conditionsEasypace SPS devices have successfully passed the tests defined by the following standards for extreme atmospheric conditions:

b IEC 68-2-1: dry cold at -55 °C b IEC 68-2-2: dry heat at +85 °C b IEC 68-2-30: damp heat (temperature +55 °C, relative humidity 95 %) b IEC 68-2-52 level 2: salt mist.

Easypace SPS devices can operate in the industrial environments defined by standard IEC 947 (pollution degree up to 4).

It is nonetheless advised to check that the devices are installed in suitably cooled switchboards without excessive dust.

VibrationsEasypace SPS 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.):

b 2 to 13.2 Hz: amplitude ±1 mm b 13.2 to 100 Hz: constant acceleration 0.7 g.

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

007A Electromagnetic disturbances

Easypace SPS devices are protected against: b overvoltages caused by devices that generate electromagnetic disturbances b overvoltages caused by an atmospheric disturbance or by a distribution-system

outage (e.g. failure of a lighting system) b devices emitting radio waves (radios, walkie-talkies, radar, etc.) b electrostatic discharges produced by users.

Easypace SPS devices have successfully passed the electromagnetic-compatibility tests (EMC) defined by the following international standards:

b IEC 947-2, appendix F b IEC 947-2, appendix B (trip units with earth-leakage function).

The above tests guarantee that: b no nuisance tripping occurs b tripping times are respected.

Cleaning b Non-metallic parts:

never use solvent, soap or any other cleaning product. Clean with a dry cloth only b 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.
