electronic components on them. You must place
these items in a location where they will not be
damaged. Use the packing box to place these
items inside, ensuring that the door & chassis
remain separated. Store them in a safe place
which is clean, dry and dust-free.
Note: Do not allow the door & chassis to
come into contact with the packing foam as
this may hold a static charge.
11. Locate the earth lead connecting the gland
plate to the earth bar. Disconnect the earth
lead from the earth bar.
12. Remove the screws securing the gland plate to
the enclosure. Remove the gland plate.
13. Use a centre punch and hammer to remove
the required knock-outs by placing the centre
punch diagonally opposite the fixing point on
the knockout and striking the centre punch with
the hammer.
DO NOT
remove the knock-outs
from any unused cable entries.
14. Refit the gland plate ensuring that the seal is
correctly seated.
15. Re-connect the earth lead from the gland plate
to the earth bar.
For Bulk Head mounting:
(a) Identify the four indented holes in the
back of the enclosure that are used to
mount the enclosure.
(b) Mark the location of one of the upper
fixing holes on the wall/bulkhead. Drill and
fix with a suitably plated or stainless steel
M5 nut, bolt and washers (fixings not
supplied). The fixing must be sealed using
two neoprene washers [supplied with the
panel
fixing kit], one fitted between the
panel and the bulkhead and the other
fitted between the panel and the steel
washer inside the panel. See Figure 1
–
Bulk Head Mounting Details. Do not fully
tighten at this stage.
(c) Level the panel and fix the remaining
fixing points as above.
(d) Check that neoprene seals have been
fitted as shown in Figure 1 then fully
tighten all of the fixing nuts & bolts.
(e) Check that the enclosure is firmly seated
against the bulk head and is not deformed
in any way.

For Console mounting:
(a) Cut a suitable hole in the console to fit the
enclosure. Dimensions are shown in
section 11.
(b) Identify the four holes in the outer flange
of the enclosure that are used to mount
the enclosure in a console.
(c) Insert the enclosure into the console. Note
that the flange will not sit flush with the
console at this stage because of the four
bushes used for securing the door.
(d) Mark the centre positions of the four
bushes. Remove the enclosure and drill
suitable sized holes to accommodate the
bushes (13mm to 15mm diameter).
(e) Insert the enclosure into the console and
check that the flange now sits flush with
the console. Drill suitable mounting holes
in the console & fix with M5 counter sunk
screws.
16. Bring all field wiring into the enclosure through
suitable cable glands, ensuring that the cable
conductors are of sufficient length inside the
enclosure (at least 30cm). Waterproof glands
and seals should be used to maintain ingress
protection against water. Ensure that all
conductors are clearly labelled. Any unused
cable entries which are open must have
waterproof knockout seals fitted.
17. Connect the earth drain wires of the field
cabling to the earth bar(s) positioned at the
back of the back-box. Up to two drain wires
may be connected to each terminal.
18. Ensure that the electrical continuity of any
cable shield is maintained through to the last
device on the circuit. The shield must only be
connected to enclosure earth in the panel by
using the earth bars provided.
19. Clear any dust and debris from inside the
enclosure.
20. Reinstallation of the chassis is the reverse of
removal. Ensure that all keyholes on the
