Note
3RM10/3RM12 Standard motor starters with 110 to 230 V AC/110 V DC control supply
voltage
The same voltage source (potential) must be used for the control supply voltage and the
control inputs.
The reference point for the
control inputs is terminal A2.
When controlling with a PLC, control must be via relay outputs.
There must be no parallel load (e.g. a lamp) connected at the control inputs in the case of
motor starters with the product version E01.
Note
3RM11/3RM13 Failsafe motor starters with 24 V DC control supply voltage
The control inputs are electrically isolated from the control supply voltage (A1, A2).
The terminals M1 and M2 are the reference point for the control inputs.
For controlling the control inputs, e.
g. via the digital outputs of a PLC, a voltage from an
SELV/PELV Class 2 supply is required.
Note
3RM11/3RM13 Failsafe motor starters with 110 to 230 V AC/110 V DC control supply
voltage
The same voltage source (potential) must be used for the contro
l supply voltage and the
-related applications.
The reference point for the control inputs is terminal A2.
When controlling with a PLC, control must be via relay outputs.
