Wall or Shelf Mounting
The charger can be fastened to a wall for wall or shelf mounting, by attaching the mounting brackets to the
last two side mounting screw holes near the rear of the charger. Then, 1/4" bolts or lag screws can be
installed in each of the (4) key slots or by using the top and bottom 0.281 diameter round holes in the
mounting brackets (4 bolts total).
Rack Mounting
The 4-slot chassis can be mounted to a standard Electronic Industries Association (EIA) 19” (483mm) rack
system. The 2-slot can also be mounted to a standard E IA 19” rack system using an optional mounting
bracket. An industry standard 3/8" square hole rack, 12-24 UNC cage nuts, and 12-24 UNC rack screws are
recommended. A 12-24 screw should be installed through each of the 2 highest slots and 1 of the 2 lowest,
0.218" X 0.312" slots in both of the 2 mounting brackets (a total of 6 screws minimum). The 12-24 screws
should be tightened to 40 in--lb. If other sizes and/or types of fasteners are used, the quantity, location and
tightening torque should be designed as recommended by the manufacturer to be at least as strong as the
above recommendation. By adjusting the locations of the mounting brackets along the 1/2" spacing of screw
holes along the side of the charger, many different mounting configurations are possible, from flush mounted
to forward mounted.
The patterns of the mounting bracket rack mounting holes and slots are shown in Figure 3 -1 (4-slot chassis).
