Installer-Supplied
Components
CAUTION
Customer wiring interface
connections are shown in the
electrical schematics and
connection diagrams that are
shipped with the unit. The installer
must provide the following
components if not ordered with the
unit:
[ ] Power supply wiring (in conduit)
for all field-wired connections.
[ ] All control (interconnecting)
wiring (in conduit) for field-
supplied devices.
[ ] Fused-disconnect switches or
HACR-type circuit breakers.
[ ] Power-factor-correction
capacitors.
Power-Supply Wiring
All power-supply wiring must be
sized and selected by the project
engineer in accordance with EN
60204.
WARNING
To prevent injury or death,
disconnect all electrical power
sources before completing wiring
connections to the unit.
All wiring must comply with local
codes. The installing (or electrical)
contractor must provide and install
the system interconnecting wiring,
as well as-the power supply wiring.
It must be properly sized and
equipped with the appropriate
fused-disconnect switches.
The type and installation location(s)
of the fused-disconnect switches
must comply with all applicable
codes.

Installation – Electrical
CAUTION
Use only copper mono-conductors
to avoid corrosion and overheating
at terminal connections.
Cut holes into the sides of the
control panel for the appropriately-
sized power wiring conduits. The
wiring is passed through these
conduits and connected to the
terminal blocks, optional unit-
mounted disconnects, or HACR-type
breakers.
To provide proper phasing of
3 phase input, make connections as
shown in field wiring diagrams and
as stated on the yellow WARNING
label in the starter panel. For
additional information on proper
phasing, refer to "Unit Voltage
Phasing." Proper equipment
grounds must be provided to each
ground connection in the panel (one
for each customer-supplied
conductor per phase).

Control Power Supply

The unit is equipped with a control
power transformer; it is not
necessary to provide additional
control power voltage to the unit.

Heater Power Supply

The evaporator shell is insulated
from ambient air and protected
from freezing for temperatures
down to
-29°C [-20,2°F] by two
thermostatically-controlled
immersion heaters and two strip
heaters combined with evaporator
pumps activation through CH530.
Whenever the ambient temperature
drops to approximately 4°C [39.2°F],
the thermostat energizes the
heaters and the CH530 activates the
pumps..
For temperatures below -29°C,
please contact your local Trane
sales engineer for advice.
CAUTION
The control panel main processor
does not check for loss of power to
the heat tape nor does it verify
thermostat operation. A qualified
technician must verify power to the
heat tape and confirm operation of
the heat tape thermostat, to avoid
catastrophic damage to the
evaporator.
CAUTION
With factory-fitted disconnect
switch, trace heating is taken from
the live side of the isolator so
power
remains on.
Supply voltage to the the heating
tapes is 400V.
In case of winter water drainage for
freeze protection, it is compulsory
to disconnect the evaporators
heaters to protect them from
burning due to overheat.
