REPLACING
5.
Prior to installing apply silicon grease 3 mils thick
to the entire base of the module.
6.
Install the two Phillips screws securing the module
to the heatsink and torque initially to 22-26 LB-IN
(2.49-2.93 NM) then final torque to 44 LB-IN (5.00
NM).
7.
Plug the gate wires into the gate lead connectors.
8.
Install the Phillips screws securing the bus bars to
the rectifier. Torque these and the remaining bus
bar screws to 18-22 LB-IN (2.03-2.49 NM). Insure
the bus sensing wire marked "K" is secured to
the lower bus bar.
9.
Install the Phillips screw securing the line
connection to the module. Torque to 18-22
LB-IN (2.03-2.49 NM). Insure the soft charge
jumper wires have been included. The three soft
charge jumper wires are labeled "R", "S" and "T"
and are connected in that order from left to right.
REMOVAL
1.
Remove the line side Phillips screw from the rectifier to be replaced.
2.
Remove the two Phillips screws from the bus bar connections of
the rectifier being replaced. Loosen but do not remove the remaining
bus bar screws on the other rectifiers.
3.
Remove the two gate wire leads from the rectifier.
4.
Remove the two Phillips screws securing the rectifier module to
the heatsink and slide the module from beneath the bus bars.
