WIRING INSTALLATION
The E2xL25UL loudspeaker is provided with 2 off M20 x 1.5
cable entries.
1 x ½” NPT adaptor and 1 x M20 stopping plug are provided.
Installation using Field Wiring Leads and Conduit
If the sounder is supplied pre-wired with flying leads, these 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.
Installation using Cable Glands without Field Wiring Leads
If the sounder is supplied without field wiring leads, the cable
connections are made into the terminal blocks on the electronic
PCB assembly. Terminal blocks are suitable for field wiring
(AWG 18-12). Strain relief has to be ensured by installation with
a suitable cable gland. Follow the markings for the terminals on
the PCB and install wiring as shown in the diagram below.
Cable glands need to be UL certified to ANSI/UL 2225 or C22.2
NO. 174-M1984. and to UL514B / CSA-C22.2 No. 18.3-12,
ratings for hazardous locations must be equal to or better than
the rating of the sounder used.
If a high IP (Ingress Protection) rating is required then a
suitable sealing washer must be fitted under the cable gland.
