7.

Using pliers, remove the wire with push-on connector from the Snubber 
Board associated with the Resistor to be replaced.

To locate its Resistor, follow the wire from the Snubber Board to its 
Resistor, carefully clipping the wire ties along the way.

8.

Follow the other Resistor wire going from the Resistor to the Positive 
Inverter Bus (beneath the Negative Inverter Bus), carefully clipping the 
wire ties along the way. Remove the screw for the Resistor wire.

9.

Remove the Resistor to be replaced by unscrewing it from the heatsink.

10.

Using isopropyl alcohol, clean any grease off of the location where the 
Resistor is to be mounted.

Install Components

1.

Apply a thin bead of thermal grease to the full length of the metal 
bottom of the new Resistor. Spread grease evenly.

2.

Align the wire with push-on connector to the right and align the wire 
with the ring lug connector to the left.

3.

Mount the new Resistor on heatsink with screws. Torque to 2.9 N•m 
(26 lb•in)

4.

Connect the wire with the ring lug connector to the original location on 
the Positive Inverter Bus.

5.

Connect the wire with push-on connector to J1 of its Inverter Snubber 
Board.

6.

Replace all wire ties.

7.

Reassemble remaining components in reverse order. 

8.

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