2. Only use cable entries and cables suitable for the prevailing ambient temperature.
3. Ensure that the power cables are strain relieved when inserting them in the terminal box.
4. Carefully connect the cables and ensure a reliable protective conductor connection.
5. Tighten the glands and the elements for the strain relief with the torque specied by the
manufacturer.
6. Check the cable entries and cables to ensure that they are correctly sealed and rmly 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 specied on the rating plate.
Cable entries, sealing plugs and thread adapters
All cable entries and sealing plugs must be approved for use in the respective hazardous zone.
• Any openings that are not being used must be sealed using the appropriate certied sealing
