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 interference between the power and communication signals continues, increase the distance until the interference is no longer a problem.
• Install the power wiring with a minimum of two (2) inches of separation from the communication cables to avoid operation problems
caused by electrical interference. Do not run power wiring and communication cables in the same conduit.
• If it is unavoidable to run the power wiring and communication cables alongside each other for long distances, refer to the table below
for minimum recommended distances between the cables.
Table 62:Power Wire and Communications Cable Minimum Required Separation Minimum Allowable Distances.
• Do not bunch the power wiring and communication cables together.
• Do not run the power wiring and the communication cable in the same conduit.
Note:
Separating Power Wires and Communication Cables
General Information
• All power wiring and communication cable installation must be performed
by trained service providers working in accordance with local, state, and
NEC regulations related to electrical equipment and wiring, and following the
instructions in this manual. In case of conflict between local, state, or NEC
regulations and the instructions in this manual, follow the local, state, or
NEC regulation.
• Undersized wiring may lead to unacceptable voltage at the unit and may
cause unit malfunction and / or a fire hazard.
• Properly ground the water source unit and indoor units. Ground wiring must
always be installed by a qualied technician. Do not connect ground wire to
refrigerant, gas, or water piping; to lightening rods; to telephone ground
wiring; or to the building plumbing system. Failure to properly provide an
NEC approved 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 NEC regulations related to electrical equipment and
wiring, and following the instructions in this manual. Generated overcurrent
may include some amount of direct current. Using an oversized breaker or
fuse may result in equipment malfunction, property damage, electric shock,
physical injury or death.
• Consider ambient conditions (temperature, direct sunlight, inclement
weather, etc.) when selecting, installing, and connecting the power wiring.
