Auxiliary voltage
REF 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 indicator LED (ready) on the front panel
will be on. For detailed information on power supply, refer to table 4.2.4-2.
The primary side of the power supply is protected with a fuse located on the PCB of
the relay.
