ing.

To Connect the Wiring to the Terminals:

1. Remove the JIS terminal screws from the (outdoor unit or indoor unit) terminal plate with a

JIS screwdriver. (See information about LG terminal connections below.)

2. Position the ring terminal around the terminal, place the terminal screw in the ring, and

tighten to the terminal plate using a JIS screwdriver.

• Firmly attach the wire; secure in a way to prevent external forces from being imparted to

the terminal block.

• Use an appropriately sized JIS screwdriver for tightening the terminals.

•

Do not overtighten the connections; overtightening will damage the terminals.

If ring terminals or fork terminals are not available, then:

• Do not terminate different gauge wires to the power terminal block. (Slack in the wiring

will generate heat.)

• When terminating wires of the same thickness, follow the instructions demonstrated in the

figures below.

•

Never apply line voltage power to the communications cable terminal block. If contact is

made, the PCBs will be damaged.

• Always include some allowance in the wiring length when terminating. Firmly attach the wir-

ing or cable, but provide some slack to facilitate removing the electrical panels while servic-

ing, and to prevent external forces from damaging the terminal block.

:Copper Wire

Terminate multiple power wires of

the same gauge to both sides.

Do not terminate two wires on

one side.

Do not terminate different gauge

wires to a terminal block.

Terminal Connections

LG uses a “JIS” type of screw for all terminals; use a JIS screwdriver to tighten and

loosen these screws and

avoid damaging the terminal. Do not overtighten

the connections — overtightening will damage the terminals — but firmly and securely

attach the wiring in a way to prevent external forces from being imparted to the termi-

nal block.
