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.

Termination and Mounting
CAUTION
!
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:

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
