FIGURE 5.2-3 shows the weight that the set of mounting bolts and their anchoring structure must
withstand for the various charger types. The “DESIGN LOAD” shows the “CHARGER WEIGHT” times a
safety factor of five (5). Be certain that both the mounting structure and the bolts will, at a minimum,
support the “DESIGN LOAD”. Drywall or plaster will not be strong enough on its own, without proper
structural reinforcement.
5.3 RACK MOUNTING
The S1, S2 and S3 cabinets can be mounted to a standard EIA 19” (483mm) rack system using the
fasteners provided by the rack manufacturer. The rear mounting flanges are configured for an EIA 19”
(483mm) rack for a forward mounting arrangement. For a recessed mounting arrangement, optional
mounting brackets can be attached to the charger sides to fit either an EIA 19” (483mm) or a 23”
(584mm) rack. See FIGURE 5.3.
FIGURE 5.3: ATTACHING RACK-MOUNTING BRACKETS
CAUTION: TO ENSURE THE STRUCTURAL INTEGRITY OF THE RACK MOUNTING
BRACKETS, USE THE SIXTEEN #10 SELF-THREADING SCREWS PROVIDED IN THE KIT. USE
EIGHT SCREWS PER BRACKET AND TIGHTEN THEM UNTIL SNUG. DO NOT STRIP THE
THREADS.
