Installing the Capacitor Control
The IntelliCap Plus neutral input is referenced to the control case ground. When the
capacitor bank control power is supplied by a transformer with a center-tapped 220-volt or
240-volt output that has the center tap referenced to ground, connect the center tap to the
Ac Neutral input and the high line to the Ac Line input of the IntelliCap Plus control. Use two
auxiliary relays with 120-volt coils and 240-volt contacts rated to meet the requirements of
the capacitor switch, and connect as indicated in Figure 20.
If the control power is supplied from a 220/240-Volt transformer that does not have a
grounded center tap, the transformer can be connected directly across the Ac Line and Ac
Neutral inputs. In this case, the auxiliary relays are not required.
