Replacing Filter Capacitors
See Publication 7000-IN010_-EN-P , “Handling, Inspection, and Storage of
Medium Voltage Line Filter Capacitors”.
1. Isolate and lock out all power to the drive.
2. Note the location of all the cables and mark them accordingly.
3. Remove the 4 power connections to the terminals, and the single ground
connector from the drive to the capacitor frame, located at the back top
right corner of the capacitor.
4. Remove the front bracket that holds the capacitor in place. At the rear of
the capacitor, there is no hardware securing the capacitor; it fits into a slot
in the assembly.
5. Remove the capacitor from the drive.
WARNING: Allow 5...10 minutes for motor capacitors to safely discharge
voltage prior to opening cabinet doors.
ATTENTION: To prevent electrical shock, disconnect the main power before
working on the drive. Verify that all circuits are voltage-free using a hot stick or
appropriate voltage-measuring device. Failure to do so may result in injury or
death.
IMPORTANT Capacitors can weigh as much as 100 kg (220 lbs). Use two or more people to
remove a capacitor.
