• For communication / connection (power) wires between the Single
Zone outdoor unit and the indoor unit for lengths up to 130 feet,
use a minimum 14 gauge, four (4) conductor, stranded, shielded
or unshielded wire. If shielded, the wire must be grounded to the
chassis at the outdoor unit only.
• When the communication / connection (power) wires between the
indoor unit and outdoor unit is GREATER THAN 130 feet, use:
• A two (2) conductor wire for power.
• A two (2) conductor wire for communication / ground.
• Separate the power AT LEAST two (2) inches away from the
communication / ground wire.
• All wiring is still minimum 14 gauge, stranded, shielded, or un-
shielded as cited above.
• Insulation material as required by local code.
• Firmly attach the cable; provide slack but secure in a way to pre-
vent external forces from being imparted on the terminal block.
• Wiring must be completed without splices.
• Always verify the communication cable is connected to a communications terminal on the Single Zone Extended Piping unit. Never apply
line voltage power to the communication cable connection. If contact is made, the PCBs will be damaged.
• The shield of the communications cable connecting the outdoor unit to the indoor unit must be grounded only to the outdoor unit frame.
• Tie the shield of each cable segment together using a wire nut at the indoor unit. Maintain polarity throughout the communication network.
• Position the incoming power to the outdoor unit away from the power / communications cables from the outdoor unit to the indoor unit.
•
Never use a common multiple-core communications cable.
All power wiring and communication cable installation must be performed
by trained service providers working in accordance with local, state, and
National Electrical Code (NEC) / UL / ETL federal regulations related to
electrical equipment and wiring, and following the manufacturer product
diagrams, requirements, and instructions in this manual. Failure to do so
will lead to electric shock which can cause physical injury or death.
