2. Product overview
2. Product overview
Motorized change-over switches (type OTM_C) are suitable for remote control. You can operate the
motorized change-over switches either electrically by using the motor operator or manually by using
the handle. The operation, either electrical or manual, can be chosen by the selector switch “Motor/
Manual” on the motor operator. Motorized change-over switches consist of the change-over switch
and the motor operator.

This is a quick guide only meant for those who need a reminder of how to operate the unit. For more
detailed instructions, see chapter 6.
3.1 Operating the motorized change-over switch electrically;
remote control
To operate the motorized change-over switch electrically:
1. Remove the handle from the switch panel. You can remove the handle in all
positions (I, 0, II).
2. Turn the Motor/Manual selector to the Motor (M) position to enable electrical operation.
Figure 3.1 Operating the motorized change-over switch electrically; remote control
3.1.1 Locking electrical operation
To disable electrical operation, lock the locking latch with a padlock. After the locking latch has been
locked, the motorized change-over switch cannot be operated electrically. You can lock electrical
operation in all positions (I, 0, II).

3.2 Operating the motorized change-over switch manually;
local operation
To operate the motorized change-over switch manually:
1. Turn the Motor/Manual selector to the Manual (Man.) position to enable manual operation and to
prevent electrical operation.
2. Attach the handle to the switch panel. You can attach the handle in all positions
(I, 0, II).
Figure 3.3 Operating the motorized change-over switch manually
To disable the manual (and at the same time also electrical) operation, lift up the locking clip to
position 0 and attach the padlock to the handle.
