Verifying tightness of cable glands
To maintain enclosure tightness and provide strain relief to the cables, all cable glands must be
tightened. Unused cable glands must remain plugged.
1. Check every cable gland that is in use:
a. Pull on the cable to verify that the cable is securely held by the cable gland.
b. Tighten the cable gland if the cable moves.
2. Check that every unused cable gland is plugged and tightened.
