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 Vac is present across the circuits 5 and 6.

UTS6BI/UTS10BI - Utilizing all of the UTS circuits is not necessary. However, circuits 9 and 10 that together

form a dedicated 240 Vac circuit must be connected to a 2-pole, 20 A circuit breaker and must receive power for

the UTS to function.

120 Vac 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 Vac circuits to be connected to the UTS. Repeat steps 2 through 6 for each

circuit.

120 Vac circuits ONLY

Together, circuits 5 and 6 form a dedicated

240 Vac circuit. DO NOT use these circuits as

individual 120 Vac circuits.

Together, circuits 9 and 10 form a dedicated

240 Vac circuit. DO NOT use these circuits as

individual 120 Vac circuits.
