PRE-INSTALLATION 

WARNING

 – 

The E2xL25UL loudspeakers are supplied with 

flying leads so it should not be necessary to open the unit 
before it is installed.

WARNING – DO NOT OPEN WHEN ENERGISED

 

 
 

CAUTI0N   -   DO NOT OPEN WHEN AN EXPLOSIVE GAS 
       

       OR DUST ATMOSPHERE IS PRESENT 

 
 
 

 
 
 
 
MOUNTING

 

The E2xL25UL loudspeaker must be mounted using the rotating 
bracket as shown.  

18° Increments

Release nut to rotate 
bracket.

 

WARNING -   EXPLOSION HAZARD - SUBSTITUTION OF  
 

        COMPONENTS MAY IMPAIR SUITABILITY  
        FOR CLASS I, II DIVISION 2.

 

 

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.
