Circuit-breaker panel: Earthing the feeder

NOTICE

Maloperation of the locking device
Can cause considerable property damage.

For a panel optionally equipped

without interlocking between locking device and three-

position disconnector

: If the circuit-breaker and the three-position disconnector are in

CLOSED position, do

not

operate the locking device.

If the locking device is operated, all electrical and mechanical opening commands (e.g.
protection tripping) are ineffective.
➭ Operate the locking device only under the following conditions:

- Three-position disconnector switched to READY-TO-EARTH position.
- Circuit

-

breaker switched to CLOSED position.

1

Initial situation

2

➭ Push the interrogation lever downwards

and hold it.

3

➭ Push the control gate to the right and hold

it (the interrogation lever locks in lower
position. The actuating opening for the
READY-TO-EARTH function opens).

4

➭ Switch the three-position disconnector to

READY-TO-EARTH position (insert the operating
lever and turn 180° clockwise).

5

➭ Remove the operating lever (the

interrogation lever and the control gate
return to their initial position. The
actuating opening closes).

6

➭ To earth the feeder, close the circuit-

breaker.

7

➭ Push the locking device upwards.

8

➭ Fit a padlock.
