f.
Measure the insulation resistance between Live and Neutral.
g.
In all cases the insulation resistance must exceed 2 MΩ.

Note: For part AS405-31-1891M0.
a.
Prepare to measure continuity using the DMM (item 1, Table 5-3) set to the applicable
resistance range.
b.
Measure the continuity between corresponding ADTS connector pin and the
conductors at the open end of the cable using the connectivity Table 5-5 below. The
measured resistance should not exceed 0.5 Ω.
Note: This resistance value is the expected maximum value for the 5 m (16 ft)
cable length supplied.
c.
Prepare to measure insulation using the Insulation tester (item 2, Table 5-3), set to
the 500 V range. This test will be most practically performed at the open end of the
cable.
d.
Measure the insulation resistance between Gray (+28 V) and Green (Protective
Ground).
e.
Measure the insulation resistance between White (0 V) and Green (Protective
Ground).
f.
Measure the insulation resistance between Gray (+28 V) and White (0 V).
g.
In all cases the insulation resistance must exceed 2 MΩ.
