It is advised to use crimped ferrules on the phase wires and lugs on the earth wires.

1.Connect the earth wire of each output cable to the earth connection bar located to the left of the metal trunking.

2.Connect the phase and neutral wires to each circuit breaker.

3.Tie the cables to the metal trunking.

Note: it is advised to make the connections from the top down.

1.Connect the NO remote shutdown contact to terminals 1 and 2 on terminal block 13 .

2.The alarm signals are transmitted by dry contacts (Umax = 250 V AC / 30 V DC, Imax = 7 A AC / 10 A DC) between terminals 3 and 4 for the type 1 alarm and between 5 and 6 for the type 2 alarm.

3.Tie the cable down to the module frame.

Warning: the remote shutdown function is not implemented using a very low safety voltage.

Consequently, the usual safety measures must be taken to avoid all risk of electrical shock when making connections for this function.
