1)  Product Table 

 

 
Ensure  the  system  power  supply  is  capable  of  providing  the  maximum  current  required  for  all  beacons.  Review  associated  cable 
size, length and quantity of beacons on each circuit. 

 
 

2)  Warnings  

 

 

 

  POTENTIAL  ELECTROSTATIC  CHARGING  HAZARD 

 

CLEAN ONLY WITH A DAMP CLOTH. 

  DO  NOT  OPEN  WHEN  AN  EXPLOSIVE  ATMOSPHERE 

IS PRESENT. 

  ALL ENTRIES M20 X 1.5MM. 

  USE  SUITABLE  RATED  CABLES  AND  CABLE  GLANDS 

IF  TEMPERATURE  EXCEEDS  AS  PER  STANDARDS 
INDICATIONS BELOW. 
FOR ATEX / IECEx / UKEX STANDARDS: 

70ºC AT ENTRY OR 80ºC AT BRANCHING POINT. 

FOR NEC / CEC STANDARDS: 

60ºC AT ENTRY OR 60ºC AT BRANCHING POINT.
