Step 3: Verify that DC Bus
Capacitors are
Discharged
a. Using a confidence-tested AC voltmeter, verify that AC power is no
longer present on the line side of the drive enclosure's main incoming
circuit breaker.
b. Visually inspect the drive to insure no lamps or indicators are
illuminated.
Step 4: Prepare for the
Replacement
a. Read and follow the lock out, tag out, and safety verifications previously
described.
b. Open the door of the drive. Refer to Figure 1 and Figure 2 , and note the
locations of the hardware in the existing Filter Capacitor Assembly.

ATTENTION: DC Bus capacitors retain hazardous voltages after input power has
been disconnected. After disconnecting input power, wait five (5) minutes for
the DC bus capacitors to discharge and then check the voltage with a voltmeter
to ensure that the DC bus capacitors are discharged before touching any internal
components. Failure to observe this precaution could result in severe bodily
injury or loss of life.
IMPORTANT Prior to the removal and installation process, it is highly recommended that the
left side panel of the enclosure be removed to gain proper access to the
capacitor bank assembly. If the left side panel cannot be removed, please call
Technical Support for assistance at 1-440-646-3434.
