Please note the following points for explosion-protected machines:
● Replace the cable glands that are not being used by appropriately certified screw plugs.
● If you are using cable glands, use only appropriately certified cable glands with strain relief.
Comply with the installation and operation conditions specified in the certificate for these
cable glands and check that they have been fully complied with.
Undrilled entry plate
If the entry plate is undrilled, you should match the number and size of the cable glands to the
operating conditions. Not applicable for terminal boxes of the Ex d type of protection.
1. Unscrew the cable entry plate.
2. Drill the required number of holes or threads in the required size into the cable entry plate.
The thickness of the plate is selected in such a way as to give a sufficient number of turns
when the holes are tapped.
Please note that you are responsible for ensuring that the entry plate still has sufficient
strength after the holes have been drilled and tapped.
3. Mount the cable entry plate and the cables with the cable glands onto the terminal box.
Inserting the cable into the terminal box
1. Only use cable entries that are suitable for the cable.
2. Only use suitable cable entries and cables for the prevailing ambient temperature.
3. Ensure that the power cables are strain relieved where they enter the terminal box.
4. Carefully connect the cable and ensure a reliable protective conductor connection.
5. Tighten the glands and the elements for the strain relief with the torque specified by the
manufacturer.
6. Check the cable glands and cables to ensure that they are correctly sealed and firmly
seated.
7. Correctly close and seal threads or holes that are not being used ensuring that the IP degree
of protection is maintained. The IP degree of protection is specified on the rating plate.
