5.5.3. Switch closing operation from isolating position
1.
Move the black slider in the grey area 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 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.
