INSTALLATION
1. Inspecting the TDU
Inspect the TDU for any signs
of obvious damage. If damage is
visible, do not proceed and call
our warranty support line at
1-800-222-5877 menu option 3,
or email at microups.warranty@

2. Choosing a location
Install in a temperature-
controlled environment free of
corrosive and conductive
contaminants. Avoid locations
near heat or water sources and
exposed to direct sunlight. For
proper ventilation, leave four
inches clearance on all sides of
the TDU. The input outlet should
be nearby and easily accessible.
3. Installing the TDU
The TDU may be installed in a
rack by attaching the brackets
to the TDU, installing the rail kit
in the rack if needed, then
installing into the rack. The
TDU may also be installed in
the vertical/tower orientation.

computer room as defined in the
standard for the protection of
electronic computer/data
processing equipment of ANSI/
NFPA 75.

There are two groups of five
outputs, one on each side of
the fan. Connect loads to each
