Cabling
3.1 Cabling Instructions
All wiring should comply with current IEE wiring
regulations (BS7671) or the applicable local wiring
regulations. Note also the requirements of EN 54-14 for
cabling and interconnection of a fire detection and alarm
system.
For information on wiring inputs and outputs refer to the
appropriate module cable and wiring instructions to
identify terminals. Refer also to
Commissioning,
Section 4.4 External Wiring Checks
for details.
Use the following rules when installing cables:
1
Cables should be brought into the cabinet through the
20mm knockouts provided on the top face of the back
box. Ensure that all openings in the back box are
closed before connecting power to the panel. For
example, if more knockouts than required have been
removed, then block the holes with blanking glands.
This is to prevent access to hazardous voltages.
2
Tails should be of sufficient length to connect to the
appropriate termination points at the commissioning
stage.
3
Cables should be screened and should be terminated
in appropriate glands to meet local wiring codes and
to preserve the integrity of the screen connection. The
cable screen is to be clamped inside the cable gland,
which must be fitted to ensure a 360
o
bond is formed
with the metal of the back box.
4
The supply to the panel must be provided with a
suitable and readily accessible double-pole mains
disconnect device. The mains supply must be suitably
fused and rated according to the specifications (see
Appendix 1, Specifications
).
5
The knockout on the extreme right-hand side should
be used for mains cable entry. DO NOT bring mains
cables in through any other knockout holes and ensure
that the mains wiring is always separated from the
low voltage wiring. Tails of mains cables should be
provided with suitable additional sleeving before
connecting to the mains terminal block.
6
All low voltage cables should have a minimum 300Vac
rating.
General cable installation notes are given in
Section 3.2,
Cable Installation Notes
.
Earth Blade Connections
Note:
All blade connections to earth incorporate a locking
barb. To remove this connection, pull the shroud
(1), NOT the earth wire from the earth blade
terminal (2).
WARNING: Risk of electric
shock. Before working on
mains connections, ensure
mains power supply to the
panel is disconnected.
