Risk of injury through electric shock and damage to the device! Bring the Bus Terminals system into a safe, de-energized state before starting mounting, disassembly or wiring of the Bus Terminals! |
Power feed terminal
Notice | |
The mains voltage should only be supplied via a power feed terminal that is suitable for 230 VAC / 120 VAC! Bus Couplers, Bus Terminal controllers and power feed terminals for 24 V are not suitable for the supply of mains voltage (230 VAC / 120 VAC) into the power contacts! They are specifically designed for voltages up to 24 V and would be destroyed higher voltage was applied to their power contacts! To supply the mains voltage (230 VAC / 120 VAC) for the power contacts, it is essential to use a power feed terminal that is designed for 230 VAC / 120 VAC (e.g.: KL9150, KL9160, KL9250, KL9260)! |
The example illustrates control of an AC motor through a KL2791. The mains voltage (230 VAC) is supplied to the power contacts via the KL9160 power feed terminal.

Protective earth (PE) If your motor needs to be earthed, connect its earthing contact directly to PE (protective earth) of your switch cabinet or sub-distribution board and not to the KL2791 dimmer terminal! |
A power feed terminal can supply several speed controller terminals.
