4.1 POWER REQUIREMENTS
The DA1222AT may be used with either 90-
140V AC or 200-240V AC for the input for ease
of use throughout the world. Always make sure
that the fuse box window located above the
power input connector displays the proper
voltage of the country where it is being used. To
change the setting first, unplug the DA1222AT,
and then squeeze the clips on either side of the
fuse box. Pull out the fuse holder and turn it 180
degrees. Reset the fuse holder into fuse box so
that proper voltage is being displayed through
the window. Re-insert the fuse box making sure
that the side clips of the fuse box lock securely
into place.
4.2 MOUNTING CAPABILITY
The DA1222AT can be easily mounted into an
equipment rack. Four mounting holes are
provided on each side of the unit. To mount a
single unit, use Altinex 19”-1U Rack Mount Ears
(part # DA1294FC). To mount two units in
tandem, use an Altinex 19”-1U Rack Mount
Shelf (part # DA1293FC). For mounting under
the table, optional brackets, such as
theTM1271, TM1272, TM1273, or TM1274 can
