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.
