5.5 Cable Tests
RISK OF ELECTRIC SHOCK
detailed in Section 6.4, "Standard Serviceability Test," on page 58, prior to
performing a cable test.
5.5.1 Hand Terminal Cables
Note: For parts AS405-33-1891M0 (2 m) and AS405-34-1891M0 (18 m).
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 six pins at each end of each cable
assembly. The measured resistance must not exceed 2.0 Ω.
c.
This resistance value is the expected maximum value for the 18 m (60 ft) cable. The
resistance value varies depending on the length of the cable.
d.
Measure insulation using the Insulation tester (item 2, Table 5-3), set to the 250 V
test range.
e.
Measure the insulation resistance between the shell of the connector and all
individual pins in turn.
f.
Measure the insulation resistance between the shell of the applicable connectors and
all pins in turn.
g.
Measure also the resistance between individual pairs of pins (i.e., 1-2, 1-3, 1-4, 1-5, 1-
6, 2-3, 2-4, 2-5, 2-6, 3-4, 3-5, 3-6, 4-5, 4-6 and 5-6). In all cases the resistance must
exceed 10 MΩ.
5.5.2 AC Power Regional Line Plug Cables
Note: For parts AA405F-1 to AA405F-16.
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 regional
power plug pin using the connectivity Table 5-4 below. The measured resistance must
not exceed 0.8 Ω.
Note: This resistance value is the expected maximum value for the longest 10 m
(32 ft) cables. The resistance value varies depending on the length of the cable.
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 regional line plug
end of the cable.
d.
Measure the insulation resistance between Live and Protective Ground.
e.
Measure the insulation resistance between Neutral and Protective Ground.
