Installation
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.
Trane provides a single power
supply which includes the
transformer.
Warranty reserves will be formulated
if a transformer, not supplied by
Trane, is installed inside the electric
panel.
CAUTION! Electrical connection to
an IT Network is not recommended
if the unit has been provided with a
speed inverter such as the low
ambient option (-18°C). Speed
inverter generates earth current
leakage that is not suitable for IT
networks without special designed
devices. For more information
contact your local Trane Sales Office.
