6-1. Measurement of Insulation
Resistance
● The insulation is in good condition if the resistance
exceeds 2MΩ.
6-1-1. Power Supply Wires
Clamp the grounding terminal of the power plug with a
lead clip of the insulation resistance tester and
measure the resistance by placing a probe on both
the two power terminals. (Fig. 1)
Then, also measure the resistance between the
grounding and other power terminals. (Fig. 1)
6-1-2. Indoor Unit
Clamp a metallic part of the unit with the lead clip of
the insulation resistance tester and measure the
resistance by placing a probe on each terminal screw
where power supply lines are connected on the
terminal plate. (Fig. 2)
6-1-3. Outdoor Unit
Clamp an aluminum plate fin or copper tube with the
lead clip of the insulation resistance tester and
measure the resistance by placing a probe on each
terminal screw on the terminal plate. (Fig. 2)
Note that the ground line terminal should be skipped
for the check.
6-1-4. 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.
