Chapter 4 – Electrical Installation
To maintain enclosure tightness and provide strain relief to the cables, all cable glands on the
DGA monitor and the power supply unit must be tightened. Unused cable glands must remain
plugged.
1. Check every cable gland that is in use:
a. Pull on the cable slightly to verify that the cable is securely held by the cable gland.
b. Tighten the cable gland if the cable moves easily.
2. Check that every unused cable gland is plugged and tightened.
