10. CHECKING ELECTRICAL COMPONENTS
10-1. Measurement of Insulation
Resistance
The insulation is in good condition if the resistance
exceeds 2M½.
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)
Then measure the resistance between the ground wire
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)
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.
