Power Wiring - LG ARNH963K2A2 Installation Manual

Keep line voltage power away from the communications cable and ter-
minals 3(A) and 4(B). Line voltage power applied to the communications
terminals will damage the indoor unit control board.
• Size all field provided electrical components per NEC and local
code. Always use copper wire.
• Maintain a minimum of two (2) inches between line voltage wires and
communications or Hydro Kit controller cables.
Procedure
1. Refer to Table 9 for each model's correct electrical data before
proceeding with these steps.
2. Provide clean 208/60/1 power to the unit.
• Maximum acceptable power fluctuation range is 188 volts to
228 volts.
3. Remove the cabinet access panel from the Hydro Kit.
4. Remove the knock-out plug from the unit end panel (Figure 25
for (K2) and Figure 26 for (K3).
• Do not use the same knock-out occupied by communications
and zone controller cables.
5. Field-install a plastic or rubber grommet to the edge of the wire
and cable cabinet access holes.
• This will prevent wire chaffing.
6. If using conduit, connect the conduit to the unit cabinet.
• Use field-provided fittings.
• Follow industry best practice procedures.
7. Provide enough slack wire at each indoor unit to connect to the
terminal block without tension on the wire.
8. Route the wire inside the control box paying special attention to
keep the wire away from communications cables by a minimum
of two (2) inches.
9. Secure the wire to the inside surface of the unit cabinet.
• Use a field provided nylon wire clamp.
10. Strip approximately half (1/2) of an inch of insulation from each
of the power wire conductors.
11. Tightly crimp a spade connector to the Hot, Neutral and Ground
Wires.
12. Insert the spade connector under the appropriate terminal block
screws.
13. Securely tighten the terminal screws.
