•
Pin #1
= white from the right channel speaker PWB
•
Pin #2
= shield drain wire
•
Pin #3
= white wire from left channel speaker PWB
•
Pin #4
= shield drain wire
– Insert the Molex connector into the
CONN401
post.
– Find the blue twisted pair from the CONN201 connector on the power management PWB.
Trim the wires so they comfortably reach the CONN402 position on the power
management expansion PWB. Insert the pins in a 4-terminal Molex connector as follows:
•
Pin #1 = blue
•
Pin #2 = blue
•
Pins #3 and #4 = filler pins
– Insert the Molex connector onto the
CONN402
posts.
– Find the #22 violet wire from the V+ post on the power management PWB. Trim the lead
length as needed to comfortable reach the +35V post on the power management expansion
PWB. Attach a quick-disconnect terminal and install on the
+35V
post.
– Find the #22 black wire from the GND post on the power management PWB. Trim the
lead length as needed to comfortable reach one of the GND posts on the power
management expansion PWB. Attach a quick-disconnect terminal and install on the
GND
post.
– Find the #22 white wire from the BIAS post on the rectifier PWB. Install on the
–60V
post
on the power management expansion PWB.
– Find the #22 white twisted pair wire from the chassis-mounted over-temperature sensor
(SW203). Trim the lead length as needed to comfortable reach the SW203 posts on the
power management expansion PWB. Attach quick-disconnect terminals and install on the
SW203
post.
– Find the #22 brown twisted pair wire from the SW203 posts on the power management
PWB. Trim the lead length as needed to comfortable reach the Loop1/Loop2 posts on the
