Route Ballast DC power cable (p/n:1-910-015-27) BEHIND
Tab that holds pursleock on top of Duct Cover. Route
Cables along top of duct cover using edge of duct as a
guide for routing cable.
Route Cables along top of duct cover. At the end of the duct, make
sure the cables are routed BEHIND the corner edge of the duct. If the
cables are not routed behind corner ridge, the cables can get pinched
when the B-Block is installed.

Apply 20x50mm himelon tape (p/n:4-079-129-21) to cables. Use
ribs on Optical Block as guides for positioning tape. Cable
should be level (horizontally) when taping.

Apply 20x50mm himelon tape (p/n:4-079-129-21) to corner of
Optical Block. Loop power cables one turn and hold bundle
with 9mm black purselock (p/n:3-703-982-02).
CAUTION
: Make sure Ballast power cables to not touch the
IRIS cable (with clear tubing sleeve). Keep as much distance
as possible between cables (EMI reasons).

Dress 15P Cable from B-Block (p/n:1-910-021-64). Dress
all cables in M4 Clamp on Bottom Cabinet.
Install 20x50mm himelon tape over 20P Connector Assy. On AGA board.
Himelon p/n:4-079-129-21
CAUTION
: Make sure tape is installed with minimum gaps between metal
shields. Take caution to route wires BEHIND terminal shield. Edges of
Metal shield are sharp (Can cut fingers/hands).

Complete AGA Wire Pre-Routing.
CAUTION
: Please take caution and note specific routing of each
cable. Variations in the routing shown is NG for minimizing EMI.
Install Connector Assembly 1-910-021-68 on AGA CN8405
CAUTION
: routing of the cable is LEFT/BELOW of ferrite core. Do
not cross cable over ferrite core. The routing shown is best for
EMI.

Install 11P (p/n:1-910-021-68) and black cable from
HPC assembly (p/n:1-910-015-31) on B-Block.
CAUTION
: 11P Conn. Assy. (with ferrite core) is routed
OVER the black HCP Conn. Assy. This routing is best
for minimizing EMI. Try not to make a variation of
shown routing.
Install 20P Connector Assembly (p/n:1-910-015-28) on B-Block side.
Make sure cable is routed OVER ferrite core and OVER 11P Conn. Assy.
(with ferrite core).
CAUTION
: Please do not make a variation of the shown wire routing. It
is NG for EMI.

CAUTION
: Please try not to make a variation of the shown wire
routing. It is NG for minimizing EMI.
Bend over M4 wire clamp on B-Block to wire dress the 11P
Conn. Assy. (with ferrite core). Main purpose is to hold the
wires against B-Block.
CAUTION
: 11P Conn. Assy. Is routed OVER black HPC Cable.
Please do not make a variation of this wire routing. It is NG for
EMI.
