Auxiliary voltage
The relay 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 is lit. For detailed information on power supply, refer to
Table 5.2.3.-2.
The primary side of the power supply is protected with a fuse located on the
printed circuit board of the relay.
