Installation Electrical
Connecting Module Power and
Control Wires
High voltage power connections are typically made at the
power distribution panel located on one end of the chiller

Labeled control and communication cables are coiled
inside each module and must be field-connected to an
Ethernet switch (if all modules are assembled on an
optional common frame, connection to the Ethernet switch
is factory provided). The Ethernet cable is routed from the
switch to each module's microprocessor controller at the
J30 connector.
Each module is equipped with a flow switch. The chiller
module will not run unless fluid is circulating through the
system and the flow switch closes when flow is detected.
Customer-installed incoming disconnect switches should
be designed for all pole disconnection and should be able
to trip during overvoltage category III.

system or individually on each module at the high voltage
panel depending on option(s) selected. Connection entries
should be made in the lower left corner of the panel(s). See

Proper Field Wiring and Grounding
Required!
Failure to follow code could result in death or serious
injury.
All field wiring MUST be performed by qualified
personnel. Improperly installed and grounded field
wiring poses FIRE and ELECTROCUTION hazards. To
avoid these hazards, you MUST follow requirements
for field wiring installation and grounding as
described in NEC and your local/state/national
electrical codes.
Chiller Module Main Power
Modular systems feature single-point power connection
from the utility service to the power distribution panel on the
primary module as standard. Main power phases A, B, and
C are connected to terminals A, B, and C respectively from
left to right. Some custom systems have individual power
supplied to each module in lieu of single point power.
