4. PREPARATION - CONNECTION

(continued)

Row positioning:

. The product shape and the positioning of the terminals allow the

passage of single-line, three-lines and plug-in supply busbars in

the upper part of the product. Then, it is possible to freely choose

the position of the connected contactor in the row and to connect

by supply busbar the other devices put on the same DIN rail.

Module maintenance:

. It is possible to switch a connected contactor in the middle of a

row supplied with an upstream busbar without disconnecting the

other devices on the same DIN rail.

4. PREPARATION - CONNECTION

(continued)

Wiring of the upstream terminals:

In case of a remote control done via a wired push button, the

control is done either via C1 and C2 terminals.

Or via a push button through the phase line protected by a circuit

breaker on terminal C1

Warning: Do not wire from Neutral to C1 or C2

Wiring of the power supply and the load (downstream

terminals):
