Mounting Instructions
The SEI DC-UPS weighs between 20 and 32 lbs, depending upon the model.
The SEI DC-UPS is designed to mount to a rack or wall without further
requirements for additional mounting kits. For wall mounting, a user-supplied 3/4-
inch plywood backboard or equivalent is required. The DC-UPS should be fastened
to the backboard using number ten wood screws. A number 27 drill can be used to
provide a pilot hole for the screws. All of the screws should be tightened with a
torque of 30 in/lb minimum and 34 in/lb maximum.
The unit should be mounted vertically in a clean dry area where the ambient
temperature does not exceed 40° C (104° F).
It is important that ventilation for the unit be provided. Leave adequate space above

that 5 inches of space be allocated around the top of the unit.
The DC-UPS is supplied with mounting angles suitable for 19" standard racks or
wall mounting.
The mounting slots on each rack adapter are spaced in conformance with EIA
standard RS-310-B.
