2.
Insert cable glands suitable for connecting cables.
Information: When selecting cable glands observe type of protection (with Ex e
or Ex d approval) and enclosure protection IP (refer to name plate).
The enclosure protection stated on the name plate IP is only ensured if suitable
cable glands are used. Thread types and thread sizes are also stated on the
name plate.

Procedure
1.
Remove cable sheathing in a length of 250 – 300 mm.
2.
Insert the wires into the cable glands.
3.
Fasten cable glands with the specified torque to ensure required enclosure
protection.
Information: For shielded cables: Link the cable shield end via the cable gland
to the housing (earthing).
