INSTALLATION
5.1
Location
The BA564G Counter is housed in a robust IP66
glass reinforced polyester (GRP) enclosure
incorporating an armoured glass window and
stainless steel fittings making it suitable for exterior
mounting in most industrial on-shore and off-shore
installations. The Counter should be positioned
where the display is not in continuous direct sunlight.
Field wiring terminals are located on the rear of the
Counter assembly as shown in Fig 4.
To ensure electrical continuity between the two
conduit or cable entries, the enclosure back-box is
fitted with a bonding plate which includes an M4 earth
stud. This bonding plate may be mounted on the
inside or outside of the enclosure. If the carbon
loaded GRP enclosure is not bolted to an earthed
post or structure, this earth stud should be connected
to a local earth or the plant potential equalising
conductor.
An insulated M4 stud is provided in the bottom right
hand corner of the back-box for interconnecting cable
screens.
Alternatively the BA564G Counter may be pipe or
panel mounted using a BA393G pipe mounting kit or
a BA394 or BA395 panel mounting kit which are
available as accessories.

Installation Procedure
Fig 3 illustrates the instrument installation procedure.
A. Remove the Counter assembly by unscrewing
the four captive 'A' screws.
B. Mount the enclosure back-box on a flat surface
and secure with screws or bolts through the four
'B' holes. Alternatively use one of the pipe or
panel mounting kits which are available as
accessories.
C. Remove the temporary hole plug and install an
appropriate IP and temperature rated M20 x
1.5mm cable gland or conduit fitting. If two
entries are required, the supplied IP66 stopping
plug should be replaced with an appropriate IP
and temperature rated M20 x 1.5mm cable gland
or conduit fitting.
D. Feed the field wiring through the cable entry in
the back-box and connect the wires to the
terminals on the rear of the instrument assembly
as shown in Fig 4. Tighten cable glands to
ensure they are sealed and replace the
instrument assembly on the back-box. Finally
evenly tighten the four 'A' screws.
