Medium Voltage Installation
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.
Medium Voltage Motor
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, the Trane
Engineering Specification for UC800 Starter By Others
(available through your local Trane office) must be
followed in order to ensure proper function and protection
of the chiller. 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.
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.
