Operation
17 Operating the panel with switch-disconnector
This chapter describes the manual operation of panels with three-position switch-
disconnector (panel types R).
Motor operating
mechanism (option)
The panels can be equipped with a motor operating mechanism for all switching operations.
The use of the motor operating mechanism is described in the circuit documentation.
Manual switching operations are also possible with motor operating mechanism. If the control
gate is operated in order to perform a switching operation, electrical switching commands are
suppressed.

17.1 Switching the three-position switch-disconnector from OPEN to CLOSED
position
Precondition • Three-position switch-disconnector in OPEN position
➭ Check service readiness (see page 85, "Ready-for-service
indicator").
➭ Remove the padlock (optional) from the locking device.
Releasing the actuating
opening
➭ Push the control gate (optional) upwards, and hold it.
✔ The actuating opening of the switch-disconnector is open.
NOTE
If the operating spring is charged with the motor operating mechanism and the auxiliary
voltage fails, the operating mechanism returns to the initial situation autonomously.
➭ Switch the auxiliary voltage on again; then, the switching process can be repeated.
