Filter Capacitor Replacement
1.
Ensure there is no power to the equipment.
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. This is 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.
6.
Install the new capacitor, sliding it back until it fits into the slot. Fasten the
front bracket.
7.
Reconnect all the power cables and the ground connection. These use
M14 hardware, but should only be tightened to 30 Nm (22 ft-lb.) due to
capacitor mechanical constraints. You may want to fasten these
connections before fully sliding the capacitor into place depending on the
available space.
8.
There are instruction labels on each capacitor detailing how to tighten the
terminal connections. Please refer to these labels.
9.
Reinstall the sheet metal that was removed, and complete one final check
to ensure connections are secure and correct.
ATTENTION:
To prevent electrical shock, ensure the main power has
been disconnected before working on the capacitor. 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
THESE CAPACITORS CAN WEIGH AS MUCH AS 100 kg (220 lb), SO
YOU WILL REQUIRE AT LEAST TWO PEOPLE TO REMOVE A
CAPACITOR.
