5.2.4. Switch closing operation from isolating position
1. Move the grey slider to the left (this releases the lever
access so the switch-disconnector can be closed).
2. Connection operation:
a. Manual operation (B driving mechanism). Insert
the lever in the switch access (red area), move the
actuating arm to the end and turn clockwise 90°.
b. Motorised operation (BM driving mechanism).
Activate the corresponding operation command.
When, for any reason, the motor stops halfway through
a motorised operation, before restarting it you must
nish the operation manually, so that the whole
mechanism: sensors, controllers, etc. are in a reliable,
eective and logical position for the control system of
the motorised unit when it is switched back on.
