Replacing Sharing Resistors
Normally the sharing resistor is part of the snubber resistor assembly.
Replacing the sharing resistor requires also replacing the snubber resistor.
The sharing and snubber resistors are normally located on the backside of the
PowerCage module. See page 72
for removing and replacing snubber resistors.
Replacing Snubber
Capacitor
The snubber capacitors are part of the capacitor assembly located behind the
PowerCage module.
1. Using a 13 mm socket wrench, remove the M8 bolt on the end of the
capacitor and retain hardware.
2. Hand rotate the capacitor counter-clockwise to unscrew it from the
threaded stud connecting it to the PowerCage module.
3. Apply a drop of Loctite 425 to the thread of the 25 mm flange side of the
replacement capacitor.
4. Hand-tighten the replacement capacitor onto the threaded stud.
5. Connect the electrical leads and hardware on the 17 mm flange side of the
replacement capacitor.
Torque M8 hardware to 7 N•m (60 lb•in).
6. Bundle and secure the connecting wires using wire ties.
IMPORTANT If the drive can be accessed from the rear, the snubber capacitors can
be removed and replaced from the rear, with the PowerCage modules in
place.
If the drive cannot be accessed from the rear, the PowerCage modules
must be removed to access the snubber capacitors. See Removing the
PowerCage Module on page 97.
Replace the capacitors one at a time. Do not remove all at once.
ATTENTION: You must insert the
capacitor in the correct orientation.
The 25 mm flange must be connected
to the threaded stud on the PowerCage
module.
