Connection check-up
1. Check individual wire installation by tugging firmly.
2. Firmly tighten cable glands and insert blanking plugs in unused cable entries.
3. Remove O-ring from lid.
4. Reinstate lid and screw in until mechanical stop. Wind back lid by one turn.
5. Mount O-ring by pulling it over the lid and tighten lid cover until you feel friction from the
O-ring on both sides. Wind lid further by one quarter of a turn to seal on the O-ring.
6. Reinstate and tighten lid lock screw.
7. Ensure that moisture does not penetrate to inside of electronics housing by creating a
drip loop (bend cables downward) immediately before cable glands.
