11.2.1 Panel Installation Instructions
1. Disconnect the display ribbon cable from the
motherboard header.
2. Disconnect the earth strap connecting the door
and backbox via the spade terminal on the door.
3. Unscrew the hinge pin at the bottom of the door
whilst supporting the door. Swing the bottom of
the door clear of the backbox and pull the door
away from the top hinge pin.
4. Place the door carefully to one side and replace
the bottom hinge pin in the backbox.
5. Unscrew and remove the two lower chassis
screws and
only slacken
the top two mounting
screws.
6. Carefully lift the chassis upward to align the
screw heads with the large holes in the chassis
keyholes. Lift the chassis clear of the upper
screws and rest the chassis in the bottom of the
enclosure. Take care not to strain the wires that
remain connected to the backbox.
7. Disconnect the earth strap connecting the
backbox and chassis at the earth bar.
8. Disconnect the flying leads from the transformer
to the mains terminal block and earth bar.
9. Remove the chassis from the enclosure and
place carefully to one side.
NOTE: The door and chassis both contain
PCBs with sensitive and fragile electronic
components on them. You must place them
in an area that is clean, dry and dust-free,
where they will not be damaged. You can
place them inside the original packing box
but you must ensure that sufficient soft
packing is used to keep the door and chassis
separated.
10. Identify the three indented holes in the backbox
that are used to mount the enclosure.
11. Place the enclosure in the desired location and
mark the position of the top indented hole.
Remove the enclosure and fit a suitable fixing to
the wall. Hang the enclosure from the top fixing
point and ensure that it is level. Mark the
locations of the other two mounting holes.
12. Remove the enclosure from the wall and fit
suitable fixings to the two remaining mounting
points. Fix the enclosure to the wall using all
three mounting points.
13. Carefully remove the required knock-outs in the
panel enclosure and gland all field wiring in
place ensuring that the cable conductors are of
sufficient length inside the enclosure. Ensure
that all conductors are clearly labelled.
DO NOT
remove knock-outs from any unused cable
entries. Any unused cable entries which are
open must be sealed with a suitable plug
(available separately).
14. Connect the earth drain wires of the field cabling
to the brass earth bar positioned at the top of the
backbox. Up to two drain wires may be
connected to each terminal.
15. Ensure that 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. [Different requirements apply for
the screen of data cable used for connecting
repeaters - see 11.2.2 below].
16. Connect the incoming protective earth conductor
to the Earth terminal in the mains terminal block.
This is the primary earth point and is labelled
[also labelled E]. See Section 5.
17. Clear any dust and debris from inside the
enclosure.
18. Connect the mains-in Live cable to the mains
terminal block [L terminal] as indicated in section
5.
19. Connect the mains-in Neutral cable to the mains
terminal block [N terminal] as indicated in
section 5.
20. Secure the mains-in cable to the cable clamp
adjacent the mains terminal using the cable tie
supplied. NOTE: The clamp should be over the
outer cable insulation.
