Introduction
Warnings, Cautions, and Notices
Safety advisories appear throughout this manual as required.Your personal safety and the proper
operation of this machine depend upon the strict observance of these precautions.
The three types of advisories are defined as follows:
WARNING Indicates a potentially hazardous situation which, if not avoided, could result in
death or serious injury.
CAUTIONsIndicates a potentially hazardous situation which, if not avoided, could result in
minor or moderate injury. It could also be used to alert against unsafe practices.
NOTICE Indicates a situation that could result in equipment or property-damage only
accidents.
WARNING
Proper Field Wiring and Grounding Required!
Failure to follow code could result in death or serious injury. All field wiring MUST be
performed by qualified personnel. Improperly installed and grounded field wiring poses FIRE
and ELECTROCUTION hazards.To avoid these hazards, you MUST follow requirements for field
wiring installation and grounding as described in NEC and your local/state electrical codes.
Failure to follow code could result in death or serious injury.
WARNING
Personal Protective Equipment (PPE) Required!
Installing/servicing this unit could result in exposure to electrical, mechanical and chemical
hazards.
• Before installing/servicing this unit, technicians MUST put on all PPE required for the work
being undertaken (Examples; cut resistant gloves/sleeves, butyl gloves, safety glasses, hard
hat/bump cap, fall protection, electrical PPE and arc flash clothing). ALWAYS refer to
appropriate Material Safety Data Sheets (MSDS)/Safety Data Sheets (SDS) and OSHA
guidelines for proper PPE.
• When working with or around hazardous chemicals,ALWAYS refer to the appropriate MSDS/
SDS and OSHA/GHS (Global Harmonized System of Classification and Labeling of
Chemicals) guidelines for information on allowable personal exposure levels, proper
respiratory protection and handling instructions.
• If there is a risk of energized electrical contact, arc, or flash, technicians MUST put on all PPE
in accordance with OSHA, NFPA 70E, or other country-specific requirements for arc flash
protection, PRIOR to servicing the unit. NEVER PERFORM ANY SWITCHING,
DISCONNECTING, OR VOLTAGE TESTING WITHOUT PROPER ELECTRICAL PPE AND ARC
FLASH CLOTHING. ENSURE ELECTRICAL METERS AND EQUIPMENT ARE PROPERLY RATED
FOR INTENDED VOLTAGE.
Failure to follow instructions could result in death or serious injury.

General Information
This section provides the following product information for the power supply module:
• Product description
• Dimensions
• Clearances
• Codes and standards compliance
• Specifications
The PM014 power supply module provides 24 Vdc forTraneinter-module communication (IMC)
buses. IMC buses are used in components ofTrane building automation systems (BAS), such as
theTracer® SC+ system controller and theTracer XM30 expansion module, and other equipment.
The PM014 uses a full-wave rectifier. It is designed to safely share power with a device that uses
half-wave rectification within the transformer limits.The power supply module has four
connections that provide power to an IMC bus:
• Two four-pin IMC pin connections for use with wiring harnesses.
• Two four-pin IMC terminal blocks for use with field wiring.

Pre-Installation
This section provides the following pre-installation information:
• Mounting location
• Transformer considerations
• Recommended configurations
Mounting Location
Important: The power supply module must be mounted onto a DIN rail inside an enclosure that
meets all local electrical codes.
Observe the following:
• The enclosure must allow for the minimum 1.8 in. (4.6 cm) vent clearance around the top and
bottom of the power supply vents.
• The mounting location must meet the temperature and humidity specifications of the power
supply as outlined in Table 3, p. 9.
• Do not mount the power supply module on a flat surface, such as on a floor or on top of a table.
Mount in an upright position with the front facing outward.
Transformer Considerations
Follow these guidelines when using transformers:
• Transformers must be class 2 rated.
• Non-class 2 transformers must be fused appropriately.
• Fully loaded power supply modules require 75 VA transformers.
The transformer size can be reduced for smaller loads on the power supply module; however,
transformers less than 20VA should not be used. Table 3 shows the recommended transformerVA
based on the PM014 output current.
Table 3. Transformer recommendations
PM014 output current Less than or equal to 0.7 Adc Greater than 0.7
Transformer VA (minimum) 40 75
