Electrical Wiring

WARNING: To prevent injury or death,
disconnect electrical power source
before completing wiring connections
to unit.

Table below provides the electrical
data for each of the units. All wiring
should confirm to NEC or applicable
codes as per requirements of local
codes and regulations. Wiring dia-
grams are furnished with the units but
extra copies can be obtained from the
Trane Sales Offices. The installer must
provide fused disconnect switches.
Type and locations of disconnects
must comply with all applicable
codes.

CAUTION :  To avoid component
failure, use copper conductor wire
only between the main power
distribution source and the unit’s
power terminals. This will prevent
galvanic corrosion or overheating at
the terminals.
1. Verify power supply available is

compatible with unit’s nameplate
ratings.

2. Refer to the unit wiring schematic

pasted to the control panel cover.

3. All factory supplied wiring are

coloured and numbered. Always
check the numbers on the wiring
to the unit terminal block against
that in the wiring diagram. Should
there be any inconsistency, please
do not hesitate to contact the
nearest  Trane Service or Sales
Organization.

4. Chilled Water Pump Motor

The installer must provide a power
supply of proper voltage and
a fused disconnect switch to the
chilled water pump motor. Provide
proper equipment grounds.

5. Flow Switch Interlock

To avoid possible evaporator
freeze-up resulting from restricted
water flow, install a flow switch
(or other flow sensing device) in the
evaporator water line. This sensing
device must be adjusted to stop
compressor operation if water flow
to the evaporator drops 50% of the
design flow rate.
