RACK SYSTEM ENCLOSURES AND
HARDWARE SYSTEMS
DESCRIPTION. The Kepco Model RA 40 Rack Adapter is designed for the installation of Kepco Switching Power Sup-
plies into a standard 19-inch Rack. In order to accommodate the various models, mounting brackets (not supplied with
the RA 40 rack adapter) are required. The mounting brackets are first attached to the power supplies, which are then
attached to the front and rear rails of the model RA 40 Rack Adapter.

INSTALLATION The Kepco Model RA 40 Rack Adapter may be bolted permanently into a standard 19-inch rack. It can
be placed onto a rack-shelf, or it may be installed with slides. The front flanges are drilled for standard (2-1/4 inch)
mounting hole distances. The sides of the Model RA 40 Rack Adapter are drilled for “Jonathan” slides (Refer to Figure
2, Mechanical Outline Drawing).
CAUTION: Since many Kepco Switching Power Supplies are convection cooled devices, sufficient airflow
around the installed power supplies and around the rack adapter must be provided (1/4 in. mini-
mum). Ambient temperature checks on the completed installation should be compared with the
specified ambient temperature ratings of the power supplies, generally 50° C without derating, up
to 70° C with output current derating (see power supply instruction manual). Heatsink or case tem-
peratures on the installed power supplies must not exceed specified limits.
First remove the front and rear covers of the RA 40 rack adapter, then install the power supplies by using applicable
mounting bracket (Table 1). Mounting hardware and installation instructions are provided with the mounting brackets.
