Notes:
1 . Breaker panel represents field power supply and is to be installed by others.
Not provided as part of the ClimaCool modular chiller system .
2 . Breaker panels can be supplied for skid mount packages or new construction
projects as options . Consult the local ClimaCool Representative .
3 . Control wiring by others .
4 . Field connections are simplified requiring only a two-conductor shielded cable
daisy chain from the master controller to the modules (see Figure 18) .

Cable Shields
Do not ground the shield to earth ground or to the control
module’s power ground . The PROT485 and the individual
control modules allow the shield to float a limited amount
so that there are no ground loops . If the voltage on the
shield becomes too great relative to the earth ground, then
the excess voltage is bled off with protective devices on the
PROT485 or on the control modules .
Noise Avoidance
Avoid running communication wires or sensor input wires
next to AC power wires or the control module’s relay output
wires. These can be a source of noise that can affect
signal quality .
Common sources of noise are:
Spark ignitors Induction heaters
Radio transmitters Large contactors (ex .motor starters)
Variable speed drives Video display devices
Electric motors (> 1hp) Lamp dimmers
Generators Fluorescent lights
Relays Parallel runs with power lines
Transformers Other electronic modules
If noise is a problem and you cannot move the wiring,
use ferrite clamp-on chokes on the cabling to improve
signal quality .
