Dynamic Braking Kits for FlexPak 3000 and WebPak 3000 Digital DC Drives

If you are using DB with a Motor Series Field, S1 connected to A2

with an Inverting Fault Circuit

Breaker:

Step 1. Follow the wiring diagram in figure 8 to connect the motor armature and the Dynamic Braking Resistor

assembly to the FlexPak 3000 drive.

Step 2. Remove the Removable Link (see figure 6). It is a bus section below the A2/S1 terminal and is

accessed through the top of the drive as shown. At the top, the A2/S1 terminal and Removable Link
are fastened with two nuts and bolts, spaced horizontally. Remove them and set them aside along
with the A2/S1 terminal for subsequent re-installation. At the bottom, remove the two bolts spaced
vertically and set them aside. Take the Removable Link (bus section) out of the drive.

Step 3. Replace the lower two vertically-spaced bolts and tighten to 23 Nm (200 in-lb).

Step 4. Replace the A2/S1 terminal fastening it with the upper two horizontally-spaced nuts and bolts

previously removed. Tighten to 23 Nm (200 in-lb).

Step 5. Route the resistor assembly harness as required. Use M10 x 25 mm screws, nuts and washers to

attach resistor assembly harness to DBR and A2/S1 connections on the drive. See figure 8.

Step 6. Connect the Inverting Fault Circuit Breaker kit to the DRV and MOT terminals as shown. Ignore the

dashed-line connection.

Step 7. Route the customer-supplied wire (cable) and attach to the connections A2/S1 and Motor A2 (or

Motor S1) as shown.

Step 8. Connect the Series Field between the terminals Motor S1 and Motor S2.

Step 9. Follow the wiring diagram in figure 5 to verify that the jumper across terminals 3 and 4 on the FIELD/

DB terminal block is installed.

Step 10. Remove the lockout and tag from the power to the drive.

Step 11. Turn on power to the drive.
