Motor operating mechanism (option)
To perform switching operations with the circuit-breaker and the three-position disconnector,
the panels can be equipped with a motor operating mechanism. The use of the motor operating
mechanism is described in the circuit documentation.
Manual switching operations are also possible at panels with motor operating mechanism. If the
locking device is operated in order to perform a switching operation, electrical switching
commands to the corresponding switching device are suppressed.
Charging the spring energy store with motor operating mechanism
If the circuit-breaker is equipped with a motor operating mechanism (option), the spring energy
store is charged automatically after applying auxiliary voltage.

Actuating opening for "spring charging"
9.7.1 Charging the spring energy store in circuit-breaker type 1.1 manually
For a circuit-breaker without motor operating mechanism (option), or in case of failure of the
auxiliary voltage supply, the operating mechanism of the circuit-breaker must be charged
manually before switching operations can be executed.
For charging the operating mechanism, use the hand crank supplied with the accessories.

2. Remove the protective cap of the actuating opening
for "spring charging".
3. Insert the hand crank into the actuating opening and
turn clockwise until the "spring charged" indicator
shows "spring charged".
✓ The "spring charged" indicator shows "spring
charged".
4. Remove the hand crank.
5. Insert the protective cap again into the actuating
opening.
✓
