Electrical Wiring - LG LK-0580CC Instrucciones De Instalación Y Mantenimiento

8. Electrical Wiring

Check the unit nameplate for the required supply voltage. Determine if adequate electrical
power is available. Refer to application specifications.
Electrical wiring and grounding must be installed in accordance with local codes and with the
National Electric code Latest Revision.
Electrical Power
It is important that proper electrical power is available for the unit. Voltage variation should
remain within the limits stamped on the nameplate.
Disconnect Switch
Provide an approved weatherproof disconnect either on the side of unit or within close
proximity.
Over Current Protection
The branch circuit feeding the unit must be protected as shown on the unit rating plate.
Power Wiring
The power supply lines must be run in approved conduit to the disconnect, and in the bottom
of the unit control box. Provide strain relief for all conduit with suitable connectors. Provide
flexible conduit supports whenever vibration transmission may cause a noise problem within
the building structure.
Power Entry Guide
Important: Holes are provided for low-voltage and high-voltage wiring. It is not
necessary to punch any new holes in either the interior or exterior unit
panels. If new holes are punched, performance will be adversely affected
unless they are resealed to be both air- and watertight.
