3 Gently lower the BIP until the bottom edge of its mounting ears touch the
top edge of the shelf mounting ears. Prevent the weight of the BIP from
resting on the shelf.
4 Align the screw holes on the 2 mounting ears with the nearest holes on
the outside face of the uprights or the adapter brackets. Loosely fasten a
10-mm (3/8-in.) screw from through the upper left mounting-ear hole.
5 Loosely fasten another screw through the lower right mounting-ear hole,
then the remaining 2.
6 Center the unit, then tighten all 4 screws to snug plus a 1/4 turn.
7 If the BIP is installed in a mounting apparatus other than a NEBS 2000
frame, ground the BIP chassis to the apparatus by firmly attaching a
ground of minimum size 6 AWG cable E/W (13.3 mm
2
) between the studs
and the common grounding point. The stud nuts on the chassis are
number 10-32 unc and are provided with star washers on the studs. There
is no metric equivalent to the stud nuts. Use the star washers between the
lug and the grounding point. Do not overtighten the nuts.
