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
Hazardous Voltage w/Capacitors!
Failure to disconnect power and discharge capacitors before servicing could result in death or
serious injury. Disconnect all electric power, including remote disconnects and discharge all
motor start/run capacitors before servicing. Follow proper lockout/tagout procedures to
ensure the power cannot be inadvertently energized. For variable frequency drives or other
energy storing components provided by Trane or others, refer to the appropriate
manufacturer’s literature for allowable waiting periods for discharge of capacitors. Verify with
an appropriate voltmeter that all capacitors have discharged.
For additional information regarding the safe discharge of capacitors, see PROD-SVB06A-EN.

WARNING
Personal Protective Equipment (PPE) Required!
Failure to wear proper PPE for the job being undertaken could result in death or serious injury.
Technicians, in order to protect themselves from potential electrical, mechanical, and chemical
hazards, MUST follow precautions in this manual and on the tags, stickers, and labels, as well
as the instructions below:
• 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 Safety Data Sheets (SDS) and OSHA guidelines for proper PPE.
• When working with or around hazardous chemicals, ALWAYS refer to the appropriate 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.
WARNING
Follow EHS Policies!
Failure to follow instructions below could result in death or serious injury.
• All Trane personnel must follow the company’s Environmental, Health and Safety (EHS)
policies when performing work such as hot work, electrical, fall protection, lockout/tagout,
refrigerant handling, etc. Where local regulations are more stringent than these policies,
those regulations supersede these policies.
• Non-Trane personnel should always follow local regulations.

Installation
1. Before beginning installation, remove power from the Unit.
2. Check to make sure all necessary parts were included in the kit.
3. 12 ½ - 25 ton units:Use the two #8-32 x ½" screws to mount the bracket to holes in front of
the ReliaTel RTRM board in the Voyager control box. See Figure 1.
3-10 ton units: Use the two #10-32 x ½" screws to mount the bracket. See Figure 2.
6 - 7½ ton split system units: If the control box does not have pre-drilled holes to mount
the bracket, using a #29 drill (Diameter 0.136" hole), drill two engagement holes in the right-
hand back corner of the control box floor. Use the two #8-32 x 1/2" screws to mount the bracket
to the Odyssey control box. See Figure 3.
10 - 12½ ton split system units:If the control box does not have pre-drilled holes to mount
the bracket, using a #29 drill (Diameter 0.136" hole), drill two engagement holes in the front
edge of the control box floor. Use the two #8-32 x 1/2" screws to mount the bracket to the
Odyssey control box. See Figure 4.
15 - 25 ton split system units: Using a #29 drill (Diameter 0.136" hole), drill two engagement
holes in the floor of the low voltage section of the control box. Use the two #8-32 x 1/2" screws
to mount the bracket to the Odyssey control box. See Figure 5.

top of the bracket. See Figure 1 - Figure 5.
6. Using two #6-32 x ½" screws, mount the Receiver back plate to the bracket.
7. Connect the included Wire Harness to the receiver J1. Route the Wire Harness through the
opening in the Receiver back plate and bracket toward the RTRM.
8. Connect the stripped ends of the Wire Harness to the ReliaTel RTRM board header J6 as
described in Table 1.
