General instructions

cgmcosmos

 system: Medium voltage switchgear  

and control gear, fully insulated in SF

 gas up  

to 24 kV with external cable test device

5.2.4.  Switch closing operation from the open position

1. 

Move the red handle to the left (this releases the access 

to the actuation shaft so the switch- disconnector can 

be closed).

2.  Closing operation:

a.  Manual operation

 (driving mechanism B) Insert 

the lever in the switch access (red area), move the 

actuating arM to one end and turn 90° CLOCKWISE.

Figure 5.6.

b.  Motorised operation

 (BM driving mechanism) 

Activate the corresponding operation order.

If, 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 motorisation when they connect with it again.

3. 

Verify that the cubicle is in connected position.
