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.
WARNING: Allow 5-10 minutes for motor capacitors to safely discharge voltage
prior to opening cabinet doors.
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.
