Gate Driver Board
Note: A full listing of test points and a detailed illustration of the gate
driver board can be found in Appendix A.
1. Push the disconnect lever to off and wait for all voltage to discharge
from the unit. Do not continue until all voltage has dissipated from the
DC bus.
2. Verify that there is no voltage across the DC bus (see Figure 4.12 and
Figure 4.13 for check points.
3. Disconnect all wiring from the main control board (J2, J3, J9, J10, J11,
J12, and TB1).
4. Remove the mounting panel for the main control board (see Figure 4.4).
5. Test fuses F1 and F3 on the gate driver board. If a fuse is damaged,
replace the board (the damaged board can be sent to Rockwell
Automation for repair).
6. Secure all wiring to the gate driver board (J1, J7, J8, J10, and TB7).
