3. Remove the M8 bolts (use 13 mm) in the two flanges that connect the
heatsink to the PowerCage module, then remove the heatsink. This
reduces the weight for easier handling.
4. To detach the PowerCage module, remove the bolts on the outer flange.
Carefully lift the module down, placing the forward face down. Do not
over-torque these bolts.
5. See appropriate section for component replacement.
6. Place the bolts on the outer flange in loosely. Torque bolts alternately on
one flange and then the opposite flange to ensure even tightening of the
module. Use the suggested torquing sequence shown in Figure 90
.

7. Replace interior assembly in the reverse order of removal.
ATTENTION: Do NOT remove the pivot plate from the PowerCage. The pivot
plate is located on the opposite end of the PowerCage from the clamp head.
If the pivot plate is removed from the PowerCage, it must be replaced in the
original orientation. See Figure 45
through Figure 50 for pivot plate location.
IMPORTANT The module can be heavy. Use two people to extract the module from the
drive.
(1) The PowerCage module is shown with switching components, heatsinks, and clamps removed for ease of lifting.
IMPORTANT A heatpipe PowerCage module does not have to be removed to access the
snubber resistors. The resistor cage can be removed within a heatpipe
PowerCage module (Figure 65
).
