INSTALLATION, OPERATION & MAINTENANCE INSTRUCTIONS FOR
ABTECH ‘HVJB’ series – SIRA06ATEX4280
Marking
The maximum power dissipation and
voltage permitted in this terminal box are
marked on the label and identified as
***W and __kV. The ambient temperature
range for which this product is suitable is
–20 to +40oC
Installation
1) Using the mounting dimensions data provided, either in the product catalogue data sheets or
on the drawings supplied, (as part of the project documentation), mark out the positions for the
mounting holes on the surface where installation is required.
2) Drill the mounting holes for either M8 or M9 fixing studs.
3) Insert the top two studs leaving 8 to 10mm protruding and lift the enclosure into position using
such assistance as may be necessary to avoid injury and hang the top fixing brackets of the
box onto the studs. Ensuring that the box is secure, insert and tighten the bottom two studs.
Now complete tightening the top two studs.
4) Unfasten the lid securing screws and remove the enclosure lid. Put the lid in a safe place.
5) Install and secure the cable glands in accordance with the manufacturers instructions.
6) Remove the top half on each cable clamp and put safely aside.
7) Remove the terminal post lock nuts, washers and the upper current bars and put safely aside.
8) Pull the cables into the box leaving trailing leads long enough to reach their respective crimp
lugs after routing through the cable clamps.
9) Trim each cable core so that the conductor end will reach the inside stop of the crimp lug on
which it is to be terminated.
10)Strip the insulation of each cable core by the length of the crimping barrel plus 2mm.
11)Remove each crimping lug in turn from the terminal post and place the securing nuts to one
side.
12)Crimp each lug onto the respective conductor ensuring that the crimp die set used is suitable
for the conductor size and is not damaged or excessively worn. The crimp die set may produce
either a hexagon type crimp or an indent type crimp. With hexagon die sets execute at least
two crimps on each lug.
13)The finished crimp should meet the tensile strength requirements of Table 2 of BS4579:Part
1:1970.
14)Route the cable core through the appropriate cable clamp and place the hole in the palm of the
now attached cable lug on to its respective terminal post, on top of the lower current bar.
15)Replace the upper current bar and secure it in place with the flat washer, spring washer and
two locknuts provided. Ensure that the spring washer is fully compressed by the first lock nut
then apply a further 1/8 to ¼ turn. Secure the fitting with the second lock nut.
16)When all the cable lugs have been attached and correctly tightened replace the top halves of
the cable clamps and tighten each one to secure the cables.
17)Replace the lid and secure it by closing the lid and tightening the lid fixing screws. Ensure that
all gland-plate securing screws are tightened.

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:-
Activity Frequency
1 Check that the lid seal is not damaged and is in place Each time the
enclosure is opened
2 Check that all lid fixing screws are in place and secured Each time the
enclosure is opened
3 Check that all gland plate fixing screws are in place and secured Each time the
enclosure is opened
4 Check that the mounting bolts are tight and free of corrosion Annually
5 Check the security of all cable glands Annually
6 Check the enclosure for damage Annually
Chemical attack
The ABTECH HVJB is manufactured from 316 stainless steel. The following additional material are
also used :-
Neoprene or silicone rubber,
Copper,
Brass,
Cast epoxy resin.
The user should give consideration to any aggressive and corrosive substances that may be
present in the environment in which these enclosures are to be used to determine the suitability of
these materials to withstand those substances.
Static hazard
The HVJB does not present a hazard from static electricity.
Vibration
The HVJB is designed for use in areas subject to normal industrial levels of vibration. They are not
designed for use in areas subject to intentional or extreme conditions of vibration.
