5.2 POWER SUPPLY AND PUMP WIRING FOR 2 OR MORE ACF60-00 UNITS
The figure shows typical wiring for 2 or more ACF60-00 units. The transformer is required to feed N.O.
contacts with low voltage current; this is done for safety reasons: when doing maintenance and a unit is shut
off, these contracts could still remain fed. In this case, no matter if pump current absorption is more or less
than 4 amp.
