Finishing the DSL connection

1. Place F connector tool in DSL.
2. In case of Ex, remove all plastic blind plug caps and mount Ex rated cable glands or Ex rated
blind plugs in unused cable entries.
To ensure IP rating, remove caps and mount appropriate cable glands and blind plugs in
unused cable entries.
Firmly tighten cable glands.
3. Check individual wire installation by tugging firmly.
4. Remove O-ring from lid.
5. Reinstall lid and screw in until mechanical stop. Wind back lid by one turn.
6. 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.
7. Ensure that moisture does not penetrate to inside of DSL enclosure by creating a drip loop
(bend cables downward) immediately before cable glands.
Note
Protection class
The DSL is IP68 only if the lid is properly mounted and all M20 holes are closed with appropriate
blind plugs or cable glands.
