blanking plug adjacent to the cable entry is permanently fixed
and must not be removed. The sounder is pre-wired with flying
leads which are colour coded and should be connected as
shown in the diagram below.
The conduit running from the supply to the sounder must
include an equipment grounding conductor that is at earth
potential to facilitate ground connection of the device. A number
of sounders can be connected in a chain to the same supply
using field installed wiring compartments that are appropriate for
the hazardous location, provided that the conductor at earth
potential can be readily connected to the ground lead on each
sounder in the chain.
