5.2.2 EARTHING SWITCH
Switch disconnector:
Close: Turn the operating handle clockwise
Open: Turn the operating handle anti-cloclwise
Earthing switch:
Before entering handle, press interlocking bracket towards
left. If the earthing switch is open, enter the handle with its
pin on the left side. If the earthing switch is closed, enter the
handle with its pin on the right side.
Earthing switch:
Close: Turn the operating handle clockwise
Open: Turn the operating handle anti-cloclwise
It may happen that the spring for the earthing switch is
discharged during the opening operation, but the earthing
switch does not open. If this happens, just continue the anti-
clockwise operation of the handle, until the earthing switch
is fully open. (check the position indicator of the earthing
switch.)
5.2.1 SWITCH DISCONNECTOR
5.2 OPERATION
Before any operation of mechanisms, make sure that front
covers are mounted.
All switch-disconnectoer and earthing switches can be
operated with the included operating handle.
All mechanisms are designed and manufactured in such a
way that all three phases are operated simultaneously. The
speed of operation is independent of the operator action. An
anti-reflex system, standard on all operating handles, prevents
an immediate re-operation of switches.
The vacuum circuit-breaker has an integrated lever for the
charging og the springs and push-buttons for operation.
Internal mechanical interlocking between the switch-
disconnector / isolator and the associated earthing switches
prevents incorrect operation. The operation of the switch
disconnector and earthing switches can be further interlocked
by means of a padlock.
