Cable Gland
The PVE-EX is required to be installed with a cable specified to the surrounding conditions and to the
given diameter of the cable gland. There are two options available for cable glands:
•
Supplied built-in cable gland (certified with the product)
•
Pre-certified standard cable gland (M20 x 1.5 mm threaded entry and 20 x 1.5 mm O-ring).
Supplied Built-in Cable Gland
The PVE-EX has a built in cable gland for cable installation. The cable gland and grommet ensures that
the internal components are not exposed to the outside. Furthermore, the cable gland arrangement has
to retain any flame and pressure that can occur inside the PVE-EX.
1. Choose the grommets delivered with PVE-EX for different cable diameters. (see the table below)
The cable gland needs to meet the diameter of the cable and to the PVE-EX.

2. Screw the cable gland at least 5 full threads.
3. Tighten the cable gland to the specified torque.
4. Install the safety wire (not included) between the cable gland and the top gland.

PVE-EX Pre-certified Cable Gland
For cable diameter specification, refer to the relevant instruction from the supplier of the pre-certified
gland. In order to comply with the product certification the pre-certified cable gland must be marked
with the following markings:

Warning
Pre-certified cable gland must have thread: M20 x 1.5 mm and must be sealed with O-ring 20 x 1.5 mm at
the threaded entry.
