5.3 Rack-Mount UPS Conversion and Installation
1. For fixed rail installations, install the rack mount handles using four (4) M4x6 screws (see
Figure 7).

2. Unpack the two fixed rail assemblies and mounting hardware. Loosen the wing nuts and extend
the inner members to their outermost position (see Figure 8).

3. Determine the height position inside the rack enclosure where you want to mount the UPS or
battery cabinet. Make sure fixed rails are at the same mounting height on each of the four (4) rack
mounting rails.
NOTE
When rack mounted, the UPS must be supported by a shelf, slide rails, brackets or fixed rails
on each side. The rack mount handles WILL NOT support the weight of the UPS. They are
used to move the UPS into and out of the rack.
!
CAUTION
Reduce the risk of tipping the rack enclosure by placing the UPS or battery cabinet in the
lowest possible rack position.
