Hand crank If the supply voltage fails, the closing spring can be charged with a hand crank.
• To do this, fit the hand crank onto the hand crank coupling through the opening
with the adapter pushed forward and
• turn clockwise until the spring state indicator changes over:
The adapter of the hand crank is designed in such a way that the hand crank be-
comes uncoupled when the motor supply voltage returns.
Closing
Provided there is no lock-out due to a mechanical locking device, send the closing
command via the CLOSE pushbutton or the corresponding command element until
the vacuum circuit-breaker is closed, and shows and signals the CLOSED switching
position.
Change of the position indicator:
After closing and, if necessary, releasing the CLOSE pushbutton, the closing spring
is immediately automatically charged by the motor and the symbol for “Closing
spring charged” becomes visible in the spring state indicator.
Change of the spring state indicator:
