5)  Special Conditions of Use 

 

When  used  for  a  Group  III  application,  the  surface  of  the 
enclosure  may  store  electrostatic  charge  and  become  a 
source  of  ignition in applications with  a low relative  humidity 
<~30% relative humidity where the surface is relatively free of 
surface contamination such as dirt, dust, or oil. 
 
Guidance  on  protection  against  the  risk  of  ignition  due  to 
electrostatic discharge can be found in EN TR50404 and IEC 
TR60079-32. 

 

End  user shall  adhere  to  the  manufacturer’s  installation  and 
instruction  when  performing  housekeeping  to  avoid  the 
potential for hazardous electrostatic charges during cleaning, 
by using a damp cloth. 
 
To  maintain  the  ingress  protection  rating  and  mode  of 
protection, the cable entries must be fitted with suitably rated, 
certified  cable  entry  and/or  blanking  devices  during 
installation.  
 
Equipment  with  the  flare  horn  shall  not be  installed  with  the 
flare higher than horizontal (to avoid accumulation of dust). 
 
The equipment  incorporates metal  parts  isolated  from  earth, 
having  capacitance  values  exceeding  the  limits  permitted  in 
the  standards  of  certification.  Mounting  bracket  –  10.33pF; 
Lens guard – 12.33pF. 
 
The equipment shall only be used in an area of at least 
pollution degree 2, as defined in IEC 60664-1. 
 

6)  Product Location and Access

 

 

6.1. 

Location and Mounting 

 

The  location  of  the  unit  should  be  made  with  due  regard  to 
the area over which the warning signal must be audible. They 
should  only  be  fixed  to services that  can carry the  weight of 
the unit. 

 

The E2x combined sounder beacon should be secured to any 
flat surface using the three 7mm fixing holes on the stainless 
steel U shaped mounting bracket. See Figure 1. The required 
angle  can  be  achieved  by  loosening  the  two  large  bracket 
screws in the side of the unit, which allow adjustment of the 
unit in steps of 18°. On completion of the installation the two 
large bracket adjustment screws on the side of the unit must 
be  fully  tightened  to  ensure  that  the  unit  cannot  move  in 
service.

6.2. 

Access to the Enclosure 

 

 

Warning – High voltage may be 
present, risk of electric shock.  
DO NOT open when energised, 
disconnect power before opening. 

 

Warning – Hot surfaces. External 
surfaces and internal components 
may be hot after operation, take 
care when handling the equipment. 

 

To access the enclosure, remove the four M4 posi pan head 
screws, M4 spring and plain washers and withdraw the cover.

To  replace  cover,  check  that  the  ‘O’  ring  seal  is  in  place. 
Carefully push the cover in place. Insert and tighten down M4 
screws,  spring  and plain  washers in  the order  shown  above 
and tighten down. 
 

7.  Selection of Cable, Cable Glands, Blanking 

Elements & Adapters 

 

When  selecting  the  cable  size,  consideration  must  be  given 
to  the  input  current  that  each  unit  draws  (see  Table  1),  the 
number  of  sounders  on  the  line  and  the  length  of  the  cable 
runs.  The  cable  size  selected  must  have  the  necessary 
capacity  to  provide  the  input  current  to  all  of  the  sounders 
connected to the line.  

 

The  dual  entries  can  be  ordered  with  one  of  the  following 
options: 
 
2-off M20 x 1.5 thread 
2-off ½” NPT thread 
1-off M20 x 1.5 & 1-off ½” NPT thread
