Chapter 3 Component Replacement Procedures
Install Components
1. Replace setscrews for each new Capacitor using a 3 mm angle hex wrench.
Each Capacitor needs a short and long setscrew; see the illustration below
for where to install each one.
2. Place Capacitors into correct position in drive (vent plug at top or
12 o’clock).
3. Place Bus Capacitor Busbar onto Capacitors.
4. Install washers and nuts onto the shorter setscrews to secure the Bus
Capacitor Busbar to the Bus Capacitors.
Note: Install all setscrews, washers, and nuts but do not tighten yet.
5. Place the Transitional Busbar in position, but do not install yet. Verify the
Bus Capacitor setscrews, Flexible Capacitor Busbars, and all washers and
nuts fit. Adjust as needed.
6. Remove the Transitional Busbar, and tighten all washers and nuts for the
Bus Capacitor Busbar. Torque to 5.6 N•m (50 lb•in).
7. Install the Transitional Busbar according to the instructions on page 32 .
8. Reconnect all wires and connectors.
9. Reassemble remaining components in reverse order.
10. Replace all safety shields and enclosure covers before applying power to the
drive.
ATTENTION: Install each capacitor so its vent plug is at the top
or 12 o’clock. Component and system damage may result if you
position any Bus Capacitor incorrectly.
