). Make sure to remove the washers, nuts, and
mounting strips first (leave the four bolts in place). The
front and rear pair of bolts are mounted in horizontal slots
across the front and across the rear of the cabinet to allow
for slight left-to-right movement. This makes it easier to
mate the bolts to the holes in the base of the CMC
assembly.
The six supplied black rubber CMC isolation mounting
strips (approximately 3 in. wide x 1/4 in. thick [2.54 cm
wide by 6.4 mm thick]) must be placed between the CMC
cabinet floor and the CMC to reduce noise due to vibration.
Two layers are placed between the front pair and rear pair
of mounting bolts (over the horizontal slots), and single
layers are placed under each of the two weld straps
(parallel to the pair of mounting bolt strips) towards the
center of the CMC. Measure the position of the weld straps
and pre-position these strips (see
and
) on the floor of the CMC cabinet before the
installation of the CMC.
Installing the CMC
Ensure that the CMC is oriented correctly so the four side-
mounted electrical termination lug pads (designated M+,
M-, L+, and L-) on the CMC (see
towards the four power cables in the CMC cabinet (with the
same designations). These electrical connections will be
made after the CMC is installed in the CMC cabinet.
Ensure to leave a minimum of a 3-in. (2.54 cm) clearance
between the right hand side sheet and the right side of the
CMC (referenced from the front). Use the air baffles as a
template to ensure proper orientation of the CMC in the
CMC cabinet.
