Inspect plugs and entire cable surface for external damage. Plug pins and sockets must show no
charring, and must not be broken. Plug housing threads must be undamaged. Cable length is
approximately 95.12 ft (29 ml.
a.
Using the high voltage tester perform test as follows:
Apply 1000 V test voltage for 1 minute each:
From main contacts A, C, G, E to ground (plug housing),
From main contacts A, C, G, E to each other,
From control circuit contacts B, D, H, F to ground (plug housing),
From control circuit contacts B, D, H, F to each other,
From main contacts A, C, G, E to control circuit contacts B, D, H, F.
b.
Short circuit the main contacts and control circuit contacts to each other. The high voltage
tester must not activate.
c.
Perform insulation test at 100 V (see step a. above). Insulation resistance must be 200
MOhm.
d.
Using the resistance tester perform test as follows:

e.
Check shield resistance between two plugs and external shielding: 24 mOhm, measured at
plug contact tongues.
a.
Unscrew plugs (1, 10, figure 5-9) on EPP III and ECS ends.
First separate plug parts (13 to 15), then part (231, then remaining parts (16 to 22).
NOTE
All unions are left hand threaded.
b.
Unsolder cable conductors from plug pins.
c.
Remove plug parts from cable.
