Installing the PMU in the INFI 90 Cabinet
NOTE: Install the IEPMU01 mounting unit from the rear of the cabi-
net, the IEPMU02 mounting unit from the front.
1. Mount the power mounting unit directly beneath the fan
assembly.
2. Secure both sides of the power mounting unit to the cabi-
net mounting rails.
3. Proceed to
Wiring Instructions
NOTE: All wiring is done in the rear of the cabinet. Wires are
color-coded. This procedure and Figure
apply to INFI 90 cabi-
nets only.
1. Attach the DC input wire harness (part number
6639443_2) to TB8, TB9, TB10, TB11 and TB12 on the power
entry panel (PEP) (see Figure
for wire assignments) to the 2
DC input terminals on the right side of the PMU as follows:
Black to top conductive strip on right hand side of PMU
(DC Com).
Red to second conductive strip on right hand side of PMU
(24/48 V).
Green/yellow to top screw of terminal block P3 (ground) on
right hand side of PMU.
2. Before installing the 0 AWG (part number 206632285_45 or
6632285_47) braided wire, shape it into a [ form to avoid over-
stressing the PMU bus bar terminals. On the left side of the
PMU at the third conductive strip (from the top), attach one end
of the first 0 AWG wire assembly (part number 6632285_47).
3. Attach the other end to the MCOM tab at the top of the
system power bus bar. See Figure
.
4. Slide heat shrink tubing over PMU connection. See Figure
. Insure that connections are properly covered, then use
heat gun to shrink the tubing into place.
5. On the left side of the PMU at the fourth conductive strip
(from the top), attach one end of the second 0 AWG wire
assembly (part number 6632285_45).
6. Attach the other end to the 5 VDC tab at the top of the sys-
tem power bus bar. See Figure
.
