Step 4 Ċ Locate the area of the Chassis where the DyĆ

namic Braking resistor is to be placed. (Refer to Figure

6.5 ) Using the two screws included in the Kit, mount the

resistor onto the Chassis. Place the longer lead pointing

to he nearer Chassis edge.

Step 5 Ċ It is necessary to connect both leads to the M

Contactor. Figure 6.6 shows the contactor and the elecĆ

trical connections for the Dynamic Braking resistor.
