Electrical connections
Caution
1. The greatest care should be taken
when cutting through passages
and installing electric wiring.
Under no circumstances should
chips of metal or cuttings of
copper or isolating material fall
into the starter panel or electric
components. Relays, contactors,
terminals and control wiring
should be covered and protected
before power supplies are
connected.
2. Install power supply cabling as
shown in wiring diagram.
Adequate cable gland should be
chosen, ensuring no foreign
bodies enter the electrical housing
or components.
Caution
1. Cabling must comply with
standards in force. The type and
location of fuses must also
comply with standards. As a
safety measure, fuses should be
visibly installed, close to the unit.
2. Only copper wiring should be
used. Using aluminium wires can
produce galvanic corrosion and
possibly lead to superheat and
failure of connection points.
As an option, Trane provides the
unique power supply which includes
the transformer. If the transformer is
not ordered, it is necessary to
foresee the power supply of the
electronic module separately.
Warranty reserves will be formulated
if a transformer, not supplied by
Trane, is installed inside the electric
panel
One temperature sensors per circuit
is provided as an accessory, in
control panel of unit. They have to be
fitted in order to measure the air
outlet temperature downstream to
the DX coil (evaporator). The SMM
control module has to be set up
according to the above temperature.
Refer to supplied wiring diagram for
connection of sensors
Note: If the sensor cables are too
short, an extension-screened cable
type will be connected as close as
possible to the sensor (50 cm max.).
This extension must be soldered and
isolated with thermo-retractable
cable sheathing. Do not install or
cross the sensor cables with the
power cable in order to avoid
electrical disturbance and affect the
operation of the SMM control
module.
