Power Wire and Communications Cables
'HVFULSWLRQ Check
Power wiring was connected to a single phase 208-230V source.
Ground wire was installed and properly terminated at the unit.
The power supplied was clean with voltage fluctuations within specifications. (±10% of nameplate).

Power wiring to the indoor units was installed per all local electrical code requirements.
Communications cable between the outdoor unit(s) and indoor units was connected in a daisy chain configuration (i.e., single
parallel chain). No “Star” or multiple parallel circuits. No cable splices or wire caps were used to connect communications cables.
Record Communication Voltage Range
LG-supplied cable was used between each indoor unit and its zone controller. No cables were spliced and no wire caps are
present.
Communication type RS-485–BUS type.
Power wiring to the outdoor unit must be solid or stranded, and must comply with all local and national electrical codes.
All communications cables from the outdoor unit to the indoor units are a minimum of 18-gauge, two conductor, stranded, shielded
or unshielded. If shielded, must be grounded to the outdoor unit only.
Used appropriate crimping tool to attach ring or spade terminals at all power wiring and control cable terminations.
Verify all ring and spade terminals are copper bearing in all communications daisy chains. Galvanized or nickel plated steel
connectors were not used.
Power wiring and communications cable from the ODU to IDU cannot be run in the same conduit and must be separated per
