point
The wire length between the cable termination and point of connection must be as
short as possible. Cable earth drain wire, where applicable, must be connected to the
nearest earth point.
Terminate each cable at the dedicated entry point on the enclosure, using the cable
manufacturers recommended techniques.
Where cables are not required to be connected to terminals then leave
400mm
tail
wire length (unless otherwise speci
fi
ed) and mark each
core
identifying its
fi
nal point
of connection. Where the cable is required to be connected, ensure it is secured to the
respective terminal.
Wiring tests
Don’t undertake high voltage insulation tests WITH THE CABLES
CONNECTED to the panel and system device terminals. Such a test
may damage the electronics circuitry in loop devices and at the
panel.
Mains & battery supply cables
The mains and battery supply cables must be installed to the stage to facilitate the
power up for commissioning, which is carried out by the Servicing organisation.
Where mains cable is to remain disconnected, its tail ends must be
insulated to prevent dangerous conditions arising in the event of
accidental switching On of the mains supply.
