Auxiliary voltage
The REM 610 requires a secured auxiliary voltage supply to operate. The internal
power supply of the relay forms the voltages required by the relay electronics. The
power supply is a galvanically isolated (flyback-type) DC/DC converter. When the
auxiliary voltage is connected, the green target LED (ready) on the front panel will
be on. For detailed information on power supply, refer to table 4.2.3-2.
The primary side of the power supply is protected with a fuse located on the PCB of
the relay.
