Closing the main power switch - S1 must take two phases to connector X1
when using compact drives or an APS-24 as auxiliary power supply of the
PS-65A and to connector X3 when using XPS or PS-25B4 power supplies.
In the case of RPS power supplies, there are three phases instead of two
and they must go to connector X1.
Opening of contactor - KM1 does not remove the supply of power to the
auxiliary power supply in any case. But opening the main switch - S1 does
and the +24 V DC are maintained until the stop takes place.
INFORMATION. It is necessary to install external protection fuses in the
power lines of the auxiliary power supply. They are internally integrated into
the main power supply.
