UTS circuits
Note:
UTS6/UTS6H - Utilizing all of the UTS circuits is not necessary. However, Circuits 5 and 6 must be
connected to the building circuit panel and must receive power for the UTS to function. Circuits 5 and 6 must
be connected to circuits that are in opposite phases so that 240 V is present across the circuits 5 and 6.
UTS6BI/UTS10BI - Utilizing all of the UTS circuits is not necessary. However, the dedicated 240 V circuits
must be connected to the building circuit panel and must receive power for the UTS to function.
120 V circuit wiring
Consult the UTS Wiring Plan table in the Quick Install Guide that was filled in previously.
1. Locate the circuit breaker on the circuit breaker panel to be connected to circuit1 of the UTS.
2. Switch the circuit breaker OFF.
3. Loosen the screw securing the electrical wire, and remove the wire.
DO NOT trim this wire.
4. Locate wires 1 IN and 1 OUT in the bundle of wires coming from the UTS. Route these wires to the circuit
breaker identified in Step 1.
5. Strip off 5/8 inch insulation from the end of the wire labeled 1 OUT.
6. Insert the stripped 1 OUT wire and the wire previously disconnected from the circuit breaker into a wire
nut supplied in accessories kit. Twist the wire nut to ensure an electrical connection between the two wires.
Tuck the wires inside the circuit breaker panel.
7. Strip off 5/8 inch insulation from the end of the wire labeled 1 IN.
8. Insert the stripped end of the 1 IN wire into the circuit breaker and tighten the screw to secure the wire.
9. Identify the remaining 120 V circuits to be connected to the UTS. Repeat steps 2 through 6 for each circuit.
120 V circuits ONLY
Together, circuits 5 and 6 form a dedicated
240 V circuit. DO NOT use these circuits as
individual 120 V circuits.
Together, circuits 9 and 10 form a dedicated
240 V circuit. DO NOT use these circuits as
individual 120 V circuits.
