Installation 

1.1 

Mounting the ESCR125 

For user convenience, the ESCR125 can be wall or floor mounted. The 4 enclosure can also be rack mounted. 

Be sure that the Wall or Floor planned for installation can support the weight of the ESCR125. 

 

 

Table 1 – 

Case Type, Weight, and Dimensions 

1.1.1

 

Wall Mounting 

To wall-mount the ESCR 125, install bolts on the wall rated to support the charger's weight plus a safety factor 

of  at  least  four  times.  Refer  to  Table  1  for  charger  weight  specifications.  Secure  the  charger  on  bolts,  add 

appropriate mounting hardware, and tighten securely. Refer to the figures below for mounting dimensions. 

NOTE:

 All dimensions are in inches. For further ESCR125 enclosure information, see the outline drawings online
