How to connect wiring to the terminals

Connecting the cable between indoor unit and outdoor unit

Connection method oftheconnecting cable(Example)

1.Dismount two-caps on the conduit panel.

2.Make a hole appropriate for the passage of connec- tion cable through on cap by tool. (for low voltage line)

3.Pass the connecting cable through the hole.

4.Properly connect the cable on the terminal block.

5.Fix the connection cable with clamp cord provided on the unit not to have strain at the terminal when the connection cable is pulled outside up to a 35 pound weight.

6.Wind the vinyl tape round the connecting cable for sealing between the surface of the connection cable and cap.

7.Mount the taped part of cable on the cap.

8.Finally, mount the holed cap with the wound cable on the conduit panel.

Loose wiring may cause the terminal to over- heat or result in unit malfunction. A fire hazard may also exist. Therefore, be sure all wiring is tightly connected.

When connecting each power wire to the corresponding terminal, follow instructions "How to connect wiring to the terminals" and fasten the wire tightly with the fixing screw of the terminal plate.

• For solid core wiring (or F-cable)

1.Cut the wire end with a wire cutter of wire-cutting pli- ers, then strip the insulation to expose the solid wire about 25mm(15/16")

2.Using a screwdriver, remove the terminal screw(s) on the terminal plate.

3.Using pliers, bend the solid wire to from a loop suit- able for the terminal screw.

4.Shape the loop wire properly, place it on the terminal plater and tighten securely with the terminal screw using a screwdriver.

• For strand wiring

		Round
	Strip

1.Cut the wire end with a wire cutter or wire-cutting pli- ers, then strip the insulation to expose the strand wiring about 10mm(3/8").

2.Using a screwdriver, remove the terminal screw(s) on the terminal plate.

3.Using a round terminal fastener or pliers, securely clamp each stripped wire end with a round terminal.

4.Position the round terminal wire, and replace and tighten the terminal screw using a screwdriver.
