Connection of the power supply
The ATC6300 has inputs for an auxiliary power supply and inputs for a supply by means of a
separate DC power source.
● The ATC6300 has a dual power supply circuit, i.e. it can be operated with AC and DC, or
with just one of the two.
● If both power supplies are connected, the power is drawn from the AC source. In this
case only a little current is drawn from the DC source for operating the power supply
circuit.
If no additional DC source is used, the permanent auxiliary power supply of the ATC6300
can be provided via terminals 13 and 14 by the following devices:
● Dual network connection
● Voltage relay
● Electromechanical relay
● UPS
