Installer-Supplied Components
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
Power Supply Wiring
All power supply wiring must be sized and selected
accordingly by the project engineer in accordance with
standard IEC 60364. 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 fuse-disconnect switches. The type and
installation location(s) of the fused-disconnect switches must
comply with all applicable codes.
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.
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. Proper
equipment grounds must be provided to each ground
connection in the panel
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.
WARNING!
To prevent injury or death, disconnect all
electrical power sources before completing wiring
connections to the unit.
CAUTION!
The use of copper mono-conductors is the
preferred solution to avoid corrosion and overheating
at terminal connections.
Control Power Supply
Chiller is provided with 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 temperature down to -20°C
by two thermostatically-controlled immersion heaters
combined with evaporator pumps activation through Tracer
UC800. Whenever the ambient temperature drops below 0°C
the thermostat energizes the heaters and the Tracer UC800
activates the pumps. If ambient temperatures below -20°C
are expected, contact your Trane local office.
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 frequently
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 heating tapes is 400V.
In case of winter water drainage for freeze protection, it is
compulsory to disconnect the evaporator heaters to protect
them from burning due to overheat.
Water Pump Power Supply
Provide power-supply wiring with fused disconnect
switch(es) for the chilled water pump(s).
Interconnecting Wiring
Chilled-Water Flow (Pump) Interlock
GVAF requires a field-supplied, control-voltage contact
input through a flow proving switch (6S51) and an auxiliary
contact (6K51). Connect the proving switch and auxiliary
contact to terminal 2 connector J2 cards (1A14). Refer to the
field wiring diagram for details.
Chilled-Water Pump Control
An evaporator water-pump output relay closes when
the chiller is given a signal to go into the AUTO mode of
operation from any source. The contact is opened to turn off
the pump in the event of most machine-level diagnostics, to
prevent the buildup of pump heat.
CAUTION!
The evaporator water pump output relay must be
used to control the chilled water pump and to benefit from
the water pump timer function at startup and shutdown of
the chiller. This is required when the chiller is in operation
under freezing conditions, especially if the chilled water loop
does not contain glycol.
CAUTION!
Refer to Freeze Protection section for information
about the evaporator circulating pump.
