SPECIAL INSTRUCTIONS FOR INTRINSIC SAFETY

 

y

For personal safety, always confirm the rating of any known hazardous or 

potentially hazardous location where the light is to be used.

BATTERY INSTALLATION

WARNING: In order to maintain the XPP-5420GX’s Intrinsically Safe 

rating,  the  only  AA  batteries  certified  for  use  with  this  light  are  the 

Duracell PC1500 or Energizer EN91 batteries.

 

y

Do not attempt to use any other brand or model of AA batteries with this light.

 

y

Do not attempt to use any type of rechargeable AA batteries with this light.

Warning: To prevent ignition of a hazardous atmosphere, do not 

remove the lens bezel or the reflector / battery carrier in the hazardous 

environment.    This  task  must  ONLY  be  done  in  an  area  known  to  be 

non-hazardous.

 

y

Loosen the locking screw located on the side of the lens cap.  NOTE:  

Do NOT attempt to completely remove the locking screw.  Doing so is not 

necessary and may damage the threads.  The screw simply needs to be 

loosened enough to allow the lens bezel to unscrew.

 

y

Unscrew the lens bezel from the housing in a counter-clockwise direction.

 

y

Turn the light upside down and carefully shake the light in order to remove 

the reflector / battery carrier.  Allow the reflector / battery carrier to slide into 

your hand.  WARNING:  Do NOT touch the reflector surface with your finger.  

Doing so may damage the reflector surface.

 

y

Using 3 – AA Duracell PC1500 or Energizer EN91 batteries (make sure 

that all 3 batteries are of the same model), install the batteries in the carrier 

paying close attention to the markings on the battery carrier for proper 

battery terminal polarity alignment.

 

y

Align the reflector / battery carrier so that the switches on the carrier are 

aligned  with  the  switches  on  the  housing.  Carefully  insert  the  reflector  / 

battery carrier back into the flashlight housing until it is fully seated in the 

housing.  WARNING:  Be careful to not touch the reflector surface with your 

finger.  Doing so may damage the reflector surface.

 

y

Replace the lens bezel by screwing it onto the housing in a clockwise 

direction.

 

y

Tighten locking screw.  CAUTION:  Do NOT over-tighten.  Doing so may 

damage the threads and impact the light’s Intrinsic Safety.
