   Component Replacement Procedures

7.

Loosen the mounting bracket screws and align the CT assembly on the 
bus bar with the remaining transducers.

8.

Torque the mounting bracket screws to 5.9 N•m (52 lb•in)

9.

Reconnect the wiring harness. Secure with a wire tie.

10.

Replace all safety shields and enclosure covers before applying power to 
the drive.

Inverter Snubber Board

Important:

The Inverter Snubber Board and its associated Resistor do not need 
to be replaced at the same time.

Refer to the figures in 

Component Diagrams and Torque Specs on page 13

 for 

these instructions.

Remove Components

1.

Read and follow the 

Safety Precautions on page 9

 and 

Important Initial 

Steps on page 11

.

2.

Perform 

Remove Main Control Panel Assembly on page 21

.

3.

Perform 

Remove Stacking Panel on page 22

.

4.

Perform 

Remove Precharge Board Assembly on page 23

.

5.

Locate the Inverter Snubber Board to be replaced.

6.

Remove the Current Transducer assembly mounted over the board to be 
replaced. 

a.

Disconnect the wiring harness from the transducer board. Clip the 
wire tie and remove the wiring harness.

b.

Remove the three 
button head screws 
that secure the bus bar.
