7.1 Connection of the power supply for the ATC6500
The ATC6500 has inputs for an auxiliary power supply and inputs for a supply by means of a
separate DC power source.
● The ATC6500 has a dual power supply circuit, that is, 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.
