Installation

UPC20+ Universal Power Controller

Dual circuit 277 VAC

Dual circuit connections provide power from 277 VAC for fluorescent ballasts (FIG. 6). Circuit board

power is provided by a separate 120/240 VAC high voltage circuit, or 12 VDC connected to terminals 1

and 6 on the low voltage terminal block. For dual circuit 120/240 VAC operation, remove the short 12

AWG wire jumper.

Wiring The UPC20+ to Either The IRX-DM+ Or IRX-SM+

Wire the UPC20+ to the sensor as shown in FIG. 7. .

Wireless IR Sensor Connection

The wireless IR sensor connections are located on P2, terminals 1 - 3. Terminal 1 is +12 VDC out,

terminal 2 is serial data in, and terminal 3 is GND. The +12 VDC is short circuit protected, and the

output supplies up to 25 mA for the remote sensor.

For dual circuit 277 VAC operation, remove both 12 AWG wire jumpers.

If motors of any kind are used, do not set to a power control mode. When a power

control mode is selected, both relays can be on at the same time. Motors can be

severely damaged if this happens.
