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  of  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
