Medium Voltage Motor
WARNING
Hazardous Voltage!
Failure to disconnect power before servicing could
result in death or serious injury.
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized. Verify that no power is
present with a voltmeter.
Note: Graphic labels (shown above) are used for CE
application only.
Important:
• Before servicing, disconnect all power
sources and allow at least 30 minutes for
capacitors to discharge.
• All electrical enclosures—unit or remote—
are IP2X.
All electrical circuits shall be treated as energized until all
lockout/tagout procedures are in place and the circuit has
been tested to verify that it is de-energized. The medium-
voltage motor terminal box cover must NOT be removed if
power is present, or if there is a possibility that power may
be present. Working on energized medium-voltage circuits
is not an approved practice for normal HVAC maintenance
or service.
The motor is suitable for remote-mounted across-the-line
(including circuit breaker starting), primary reactor,
autotransformer, or solid-state starting. Refer to the unit
nameplate for motor data including RLA, LRA, etc.
In all cases of non-Trane supplied starters, a disconnecting
means and short-circuit protection must be installed ahead
of the starter, unless they are included as part of the starter.
Note: Trane assumes no responsibility for the design,
documentation, construction, compatibility,
installation, start-up, or long term support of starters
provided by others.
Motor Terminal Box
A large steel motor terminal box is provided to allow for the
field connection of the motor power supply wire to the
motor. There are three sizes available depending on
voltage and motor frame size.
