Safety for use
All switching operations take place with high-voltage
compartment doors closed.
Electrical switch positon indication on panel fornt for cir-
cuit-breaker, earthing switch and truck position.
Logical interlocks prevent maloperation.
Positively driven shutters protect against accidental con-
IP4X tact with live parts.
Standard degree of protection IP4X against electric
shock and ingress of solid foreign bodies.
Interlock
Operating levers can only be inserted when the inter-
locking conditions are fulfilled. In this way, undue stress
on the interlock mechanisms is avoided.
The following operations can only take place when the
stated interlock conditions are fulfilled:
Move the withdrawable part from the test position to the
service position:
High-voltage compartment door closed
VCB or VC in the OPEN position
(Make-proof) earthing switch in the OPEN position
Move the withdrawable part from the service position to
the test position:
VCB or VC in the OPEN position
Operate the VCB or VC:
Withdrawable part have been locked in the test position
or the service position.
Operate the (make-proof) earthing switch:
Withdrawable part have been locked in the test position.
Cable compartment door closed
Opening the high-voltage compartment door
Withdrawble part have been locked in the test position
