The gures above are based on parallel lengths up to 328 feet long. For lengths in excess of 328 feet, the
distances will have to be recalculated in direct proportion to the additional line lengths involved.

If the power supply waveform continues to exhibit some distortion, the space between the power wiring and
communication cable should be increased.
Position the power wiring a minimum of two (2) inches away from the communication cables to avoid operation problems caused by electri-
cal interference. Do not run both in the same conduit.
If it is necessary to run the power wiring and communication cable alongside each other and cannot be avoided, see Table 30 below for
minimum recommended distances.
Table 30: Power Wire and Communications Cable Minimum Required Separation Minimum Allowable Distances
Do not secure the power wiring and communication cables together.
Do not run the power wiring and the communication cable in the
same conduit. Doing so will result in communication issues due to
electrical noise and motor current leakage.
Separating Power Wires and Communication Cables
All power wiring and communication cable installa-
tion must be performed by authorized service pro-
viders working in accordance with local, state, and
National Electrical Code regulations related to electrical equipment
and wiring, and following the instructions in this manual.
Undersized wiring may lead to unacceptable voltage at the unit and
may cause unit malfunction and be a fire hazard.
Properly ground the Single Zone outdoor and indoor unit. Ground
wiring is required to prevent accidental electrical shock during cur-
rent leakage.
• Ground wiring must always be installed by a qualied technician.
Do not connect ground wire to refrigerant, gas, or water piping; to
lightning rods; to telephone ground wiring; or to the building plumb-
ing system. Failure to properly provide a National Electrical Code-ap-
proved earth ground can result in equipment malfunction, property
damage, electric shock, physical injury or death.
Install appropriately sized breakers / fuses / overcurrent protection
switches and wiring in accordance with local, state, and National
Electrical Code regulations related to electrical equipment and wir-
ing, and following the instructions in this manual. Using an oversized
breaker or fuse may result in equipment malfunction, property dam-
age, electric shock, physical injury or death.
Consider ambient conditions (temperature, direct sunlight, inclement
weather, etc.) when selecting, installing, and connecting the power
wiring.
Properly ground the Single Zone outdoor and indoor unit. Inproper-
ly ground wire can cause communication problems from electrical
noise, and motor current leakage. Ground wiring must always be in-
stalled by a qualied technician.
If the system operates in reversed phase, it may damage the com-
pressors and other components.
If there is a possibility of reversed phase, phase loss, momen-
tary blackout, or the power goes on and off while the system is
operating, install a field-supplied phase loss protection circuit.
