The DPM Reader is not intrinsically safe.  Do not operate or maintain the DPM Reader 
in  any  environments  classified  as  hazardous  as  it  may  ignite  flammable  gases.  The 
Reader contains a single internally mounted Lithium Iron Phosphate battery pack with 
a rating of 12.8VDC 6.4AH (81.9WH). 

Any  devices  that  connect  to  the  data  ports  must  comply  with  clause  4.7  of  AS/NZS 
60950.1. 

2.2 

Mains

 

Voltage

 

 

 

All  electrical  work  should  be  carried  out  in  accordance  with  the  state,  federal  or 
applicable national electrical wiring codes and regulations. 

The AC Mains electrical point into which the reader is to be connected, must have been 
installed by a qualified electrician. The provided AC mains cable with special connector 
interface for termination into the enclosure is one (1) meter in length and therefore we 
recommend  that  the power  socket  dedicated  to  the  DPM  Reader  should  be  installed 
within 500mm of the left-hand side of the enclosure. The socket should be wired through 
a suitable circuit breaker via an RCD device. 

Two labelled isolation switches are provided on the left-hand side of the DPM Reader. 
One is  to isolate  the AC mains, the other is to isolate the internal battery  DC source 
during  service  or  whilst  being  transported.  An  additional  LED  illuminated  low  profile 
power  switch  is  located  on  the  same  side  as  the  isolator  switches,  labelled  POWER 
which powers the internally mounted PLC and electronics. 

Access  into  the  DPM  Reader  is  intended  for  suitable  electrically  qualified  service 
personal ONLY. Although an access key is provided with the DPM DPMRA01.A Reader, 
there  is  no  requirement  to  open  the  hinged  door  on  the  reader  whilst  installing  the 
reader. 

Please  be  aware  that  if  the  access  door  is  opened  for  any  reason,  DIRECT 
exposure to live AC Mains contact points will be a very real danger.
