9.6 Operating the panel with circuit-breaker type 2
9.6.1 Charging the spring energy store in circuit-breaker type 2 manually
146/174
This chapter describes the manual operation of a panel with circuit-breaker type 2 and three-
position disconnector (panel types L and V).
The operations are exemplarily shown for a circuit-breaker feeder (panel type L).
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.
To deactivate the blocking of the operating mechanism and the interlocks, switch the
auxiliary voltage on again.

L2
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.
No-load switching operations at the circuit-breaker
The circuit-breaker can be damaged by no-load switching. After charging the spring energy
store, do not open the circuit-breaker directly.
⇨ After charging the spring energy store, close the circuit-breaker first, and then open it.
To insert the operating lever, a spring resistance must be overcome in the actuating opening.
