10. CHECKING ELECTRICAL COMPONENTS

10-1. Measurement of Insulation Resistance

Ground wire

Clip

●The insulation is in good condition if the resistance exceeds 2M½.

Probe

10-1-1. Power Supply Wires

Clamp the ground wire of the power supply wires with the lead clip of the insulation resistance tester and measure the resistance by placing a probe on either of the power wires. (Fig. 1)

and the other power wire. (Fig. 1)

10-1-2. Indoor Unit

Clamp an aluminum plate fin or copper tube with the lead clip of the insulation resistance tester and mea- sure the resistance by placing a probe on each termi- nal screw on the terminal plate. (Fig. 2)

Note that the ground line terminal should be skipped for the check.

10-1-3. Outdoor Unit

Clamp a metallic part of the unit with the lead clip of the insulation resistance tester and measure the resis- tance by placing a probe on each terminal screw where power supply lines are connected on the terminal plate. (Fig. 2)

10-1-4. Measurement of Insulation Resistance for Electrical Parts

Disconnect the lead wires of the desired electric part from terminal plate, capacitor, etc. Similarly disconnect the connector. Then measure the insulation resistance. (Figs. 3 and 4)

NOTE

Refer to Electric Wiring Diagram.

If the probe cannot enter the poles because the hole is too narrow then use a probe with a thinner pin.
