2.2.3 Mounting the Enclosure
Firstly, remove the required knockouts for the
installation wiring. There are sufficient
knockouts on the top of the enclosure for all
installation wiring. In addition, there are
knockouts at the top of the back wall, if
required, for rear entry cabling.
The diagram opposite shows the positions of
the four holes. Use all four positions to ensure
the panel is held securely to the wall.
Drill the required holes in the supporting wall
using a drill bit diameter 7.0 mm and plug with
a suitable 40mm long expansion plug. Affix the
panel to the wall with M5 screws (length
40mm) or No.10 screws (length 1½”).
Ensure that there is sufficient space to allow
the door to be opened when the panel is
mounted.
Finally, use a brush to remove any dust or
swarf from inside the enclosure.

2.2.4 Remounting the Chassis
Carefully replace the chassis and locate onto the upper two screws. Replace the bottom two screws and tighten
all four screws to hold the chassis securely to the back box.
Reconnect the chassis earth cable to the spade terminal in the rear of the enclosure.
2.2.5 Recommended Cable Routing Arrangement
It is recommended that the routing
arrangement shown in the diagram
opposite be employed.
Segregate the low voltage wiring (Loop
Circuit, Sounder Circuits, RS485 and
AUX Supply) from the AC Mains Wiring
and any wiring connected to the relay
contacts.
Eyelets are provided in the rear of the
back box to enable the cables to be
securely fastened using tie-wraps.
Sounders and AUX wiring should be
routed behind the chassis assembly and
tie-wrapped to the back box.
Cable screens / shields should be
connected to the back box using the
threaded studs provided near the
knockout holes. Multi-way Bus bars are
available separately for mounting on the
threaded studs.
Refer to
on cable types to be used.
Refer to specific sections on how to install AC
Mains input and loop, sounder, relay and AUX
outputs circuits.
