Wiring PowerLogic P3 Protection Relay

  1. Connect the PowerLogic P3 protection relay wires as indicated on the matching labels you have stuck on each wire:
    1. For example, for the wire marked PowerLogic X3 20 / Sepam A 15, locate the connector X3 (A) and the pin A15 (B) on the wiring mask.
    2. Connect the wire marked PowerLogic X3 20 / Sepam A 15 in the A 15 pin.
    3. Do the same previous steps for each wire to be connected by applying the correspondence marked on the label.
  2. NOTICE
    hazard of erroneous wiring
    When the residual current is measured by a current transformer, you must check the bridge of terminals in the CCA634 connector (module of the Sepam), and apply the expected and corresponding wiring. Refer to the table below.
    Failure to follow these instructions can result in equipment damage.

    Configuration 1: the bridge of terminals in the CCA634 connector does not include pin 9:

    Configuration 2: the bridge of terminals in the CCA634 connector includes pin 9:

    The wiring diagram is the following:

    DANGER
    HAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC-FLASH
    Before performing any intervention:
    • Connect the PowerLogic P3 protection relay to earth with a nut and washer using any of the indicated stud terminals.
    • Connect the earthing cable between the mounting case stud and that on the LV compartment or equipment rack.
    • Check equipotential earthing network and test earth during installation.
    Failure to follow these instructions will result in death or serious injury.
  4. The earthing cable is already fixed on the mounting case. Check the tightening torque is 1.2 N·m (10.6 lb·in).
