Trane RTHD Installation Instructions Manual page 3

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.
WARNING
Conform to All Applicable National, State,
and Local Electrical Codes!
Failure to follow all applicable codes could result in an
arc flash event, electrocution, explosion, or fire, which
could result in death or serious injury.
Users MUST conform to all applicable national, state, and
local electrical codes during the electrical installation
and servicing of this product.
WARNING
Refrigerant under High Pressure!
Failure to follow instructions below could result in an
explosion which could result in death or serious injury or
equipment damage.
System contains refrigerant under high pressure.
Recover refrigerant to relieve pressure before opening
the system. See unit nameplate for refrigerant type. Do
not use non-approved refrigerants, refrigerant
substitutes, or refrigerant additives.
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 a
CAT III or IV voltmeter rated per NFPA 70E that all
capacitors have discharged.

NOTICE
Excessive Cable Lengths Between AFDR
Drive and Compressor Motor!
Trane assumes no responsibility for equipment damage
caused by use of improper cable lengths. The variable
frequency drive industry recommends that the length of
the electrical cables connecting a drive unit to a motor
should be kept to less than 250 feet to protect the motor
from reflected voltage waves that can cause the motor
to fail. Cable lengths that exceed 250 feet between the
drive and the motor create the potential for damage to
occur to the motor windings and/or insulation.
