- The monitoring relay monitors the correct phase sequence L1-L2-L3 (direction of rotation to the right) and complete failures of individual phase voltages
- The phase voltages to be monitored are connected to the terminals L1-L2-L3; the terminals 11, 14 or 21, 24 of the relay output contacts are connected ahead of the field coil of the motor relay

- If the phase sequence is correct, the output relay is activated (green LED is on)
- In case of total failure of a phase, the output relay returns to its neutral position (green LED is off)
- A special supply voltage is not required for the monitoring relay
- Only connect the device to N if the three phases to be monitored are connected to N over an electric circuit (e.g. temperature monitoring or similar)
