Earthing/Grounding

The HVJB unit is provided with an internal and external earthing/grounding facility. This must be

connected to the appropriate earth bonding circuit before electrical power is connected to the

contents of the enclosure. Any earth/ground conductor brought into the enclosure must be

terminated onto the enclosure internal earth/ground stud.

Operation

1. The lid must be secured using all the lid screws provided in order to maintain the IP rating.

2. No attempt must be made to remove the enclosure lid whilst electrical power is connected to

the contents of the enclosure.

3. The earthing/grounding facility must be connected to the earth bonding circuit at all times when

electrical power is connected to the enclosure.

Maintenance

Routine maintenance is a requirement of IEC 60079-17:1996 and is also likely to be a requirement

of local Health and Safety legislation. The laws of the applicable country must be considered and

maintenance checks carried out accordingly.

Additional checks that are advisable to ensure the efficiency of ABTECH 'S' range enclosures on

which the HVJB is based are:-
