First closing operation
Note
If an undervoltage release 3AX1103... is fitted, it must be connected to control
voltage for switching operations (mechanical or electrical), as otherwise closing
is not possible.
If all functions have been checked and are OK, switch on the high voltage while ob-
serving all of the safety regulations and operational requirements.
Charging the closing spring
WARNING
Risk of injury if hand cranks other than the original hand crank are used.
When the supply voltage is present, the motor immediately recharges the spring
after a closing operation. If the hand crank does not have a slip coupling, the hand
crank will also rotate.
To avoid injuries caused by the motor starting suddenly, the vacuum circuit-
breaker must be charged only using the original hand crank.
If the supply voltage is applied, the closing spring is automatically charged by the
motor.
