5.4.4. 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 connected).
2.
Closing operation:
a. Manual operation
(B driving mechanism). Insert
the lever in the switch access (grey area), move the
actuating arm to the end and turn clockwise 90º.
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
finish the operation manually, so that the whole
mechanism: sensors, controllers, etc. are in a reliable,
effective and logical position for the control system of
the motorised unit when it is switched back on.
