TRANSFORMER MODULES 115VAC AND 230VAC Wiring compartment TM115 MODULE On/Off switch Description The TM115 and TM230 transformer modules are designed as self-contained, stand-alone devices. • The TM115 module converts 115VAC to two 24VAC outputs. The unit includes an On/Off switch and a 115VAC power receptacle. • The TM230 module converts 230VAC to two 24VAC outputs. The unit includes an On/Off switch. Each of the 24VAC outputs for the TM115 and TM230 has a replaceable fuse for circuit protection.

The 115VAC 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. Input Power Connections Figure 1 Power wiring to TM115 To connect electrical power to the Transformer Module: TM115 1. Mount the Transformer Module, if required, using the hole in the electrical wiring compartment and the mounting flange at the bottom of the unit. 2. Install electrical wiring from utility power to the Transformer Module. 3. Use copper wires only; proper wiring to use for power is 14/2 AWG solid copper wire with ground. Strip wire 1/2". 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 Knockout for external wiring Wire nuts connecting electrical wiring Ground 24VAC output (TB1) Figure 2 Power wiring to TM230 TM230 Knockout for external wiring Ground Line (L1) Neutral (L2) 5. Secure the incoming electrical service wires to the TM115 input wires with wire nuts as shown in Figure 1 or to the TM230 connectors as shown in Figure 2. 24VAC output (TB1) 24 VAC Output Power Connections Troubleshooting To connect to the 24VAC outputs: A common problem and possible solution are shown in the table below. For further information or if you have other problems with the unit, consult your local dealer, Liebert representative or the Liebert Worldwide Support Group. 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 1 and 2. TB1 and TB2 are NOT polarity sensitive. 4. Secure the wires to the connector. Problem 24VAC power not available from TB1 or TB2 Possible Solution Check fuse for respective output (TB1 or TB2). Replacement fuse part numbers are: • LITTLEFUSE 218002 or • BUSSMANN GDC-2A Ordering Information Quantity Part # TM115 TM230 Description Transformer Module 115VAC with two 24VAC outputs (40VA each) and 115VAC receptacle Transformer Module 230VAC with two 24VAC outputs (40VA each) SL-31150 Product Specification/Installation Sheet page 2 12/03 (Rev. 0)
