ABB Change-over switches Installation Guide
Installation Instruction, OTM_FC
OTM30-125-C_
Mounting Positions
Control Circuit
Only an authorised electrician may perform the electrical installation and
maintenance of motorized switch. Do not attempt any installation or
maintenance actions when a motorized switch is connected to the electrical
mains. Before starting work, make sure that the switch is de-energised.
-
Terminal for motor operator voltage supply
-
Control terminal for push buttons
-
Terminal for state information (also used with the automatic control unit)
-
Control terminal for automatic control unit (If used OMD controller)
Do not couple power for the control terminal. See the correct terminal for the power supply.
Manual operation: Local
Electrical operation is prevented when the handle is attached to the switch panel.
Electrical operation: Remote
Never open any covers on the product. There may be dangerous external control voltages inside the motorized switch even if the voltage is turned off.
Never handle control cables when the voltage of the motorized switch or external control circuits are connected.
Exercise sufficient caution when handling the unit.
Automatic Operation
Resetting Fuse
Impulse Control
Continuous Control
If a new command is given before the switch has reached the position of the previous command, the internal protection may operate.
Locking
Prevent Manual and Electrical Operation
Locking Possible at any position. Check position before locking.
