! CAUTION

The 115VAC/230VAC Transformer Module must be connected to a branch circuit with 15A branch circuit protection.

This equipment is intended to be installed by a qualified and certified electrician who must review and approve customer supplied wiring and circuit breakers, verify correct input and grounded connections to ensure compliance with the technical standards and national and local electrical codes.

The Transformer Module shall be used only as indicated by the manufacturer.

! WARNING

Be sure that the Power On/Off switch is set to OFF before installing any wiring to this unit. The switch is at the bottom of the unit.

To connect electrical power to the Transformer Module:

1.	Install electrical wiring from utility power to the Transformer Module.
2.	Use copper wires only; proper wiring to use for power is 14/2 AWG copper wire with ground.
3.	For the TM230 only: strip wires 3/8" (9.6mm).
	Note: For the TM115, wires are pre-stripped 0.4" (10.2mm) at the factory.
4.	Connect the wiring as follows:

	TM115	TM230	Connection Type

	White wire	Neutral (L2)	Neutral

	Black wire	Line (L1)	Power (Line)

	Green wire	Ground lead	Ground

5.	Secure the incoming electrical service wires to the TM115 input wires with wire nuts as shown in
	Figure 7 or to the TM230 connectors as shown in Figure 8.

24 VAC Output Power Connections

To connect to the 24VAC outputs:

1.Install electrical wiring from device requiring 24VAC power to the Transformer Module.

2.Use copper wire only; proper wiring to use for power is 18, 20 or 22 AWG copper wire. Strip wire 1/4".

3.There are two 24 VAC output connectors (TB1 and TB2). Terminate wires to the connector as shown in Figures 7 and 8. TB1 and TB2 are NOT polarity sensitive.

4.Secure the wires to the connector.
