Rack Mounting 

The  charger  can  be  mounted  to  a 
standard 

Electronic 

Industries 

Association 

(EIA)  19”  (483mm)  rack 

system  using  the  fasteners  provided  by 
the  rack  manufacturer.    The  horizontal 
spacing  of  the  vertical  rows  of  holes  is 
specified 

by 

EIA-310 

at 

18-

5/16” 

(18.312)(465.1mm).    The  mounting 
flanges  are  configured  for  an  EIA  19” 
(483mm)  rack  for  a  forward  mounting 
arrangement  (note:  the  width  from  the 
outer edge fo one mounting flange to the 
outer  edge  of  the  other  mounting  flange 
is  19-

15/16”).    Fasteners  to  match  the 

thread of the rack should be used in all 7 
rack mounting horizontal slots on each of 
the  2  mounting  flanges  (14  rack 
mounting  slots  total)  to  maximize  the 
mounting integrity.  The fasteners should 
be  torqued  to  22  inch-pounds.    The 
dimensions  and  pattern  of  the  mounting 
flange  rack  mounting  slots  is  shown  in 
figures 4.2 and 4.3
