For 1397-DB-B400L — B600L Kits
If You are Using DB with a Motor Series Field
— S1 connected to A2 — with an Inverting Fault CIrcuit Breaker . . .
Remove and lockout all power to the drive and follow the wiring diagram above.
➊ Follow the wiring diagram above to connect the motor armature to the drive and Inverting Fault Circuit Breaker.
➋ Remove the connector bar link at A2/S1, but retain the A2/S1 connection bar and all (4) mounting bolts.
➌ Replace the (2) lower bar bolts removed previously. Torque to 23.00 N-m (200 lb.-in.).
➍ Replace the upper A2/S1 terminal bar using the (2) upper bar bolts removed previously. Torque to 23.00 N-m
(200 lb.-in.).
➎ Connect the Inverting Fault Circuit Breaker kit to the DRV and MOT terminals as shown. Refer to the Inverting
Fault Circuit Breaker Installation Instructions for additional information.
➏ Route customer supplied cable between A2/S1 and motor connection A2 or S1. Cable should be sized to the
same guage as the DB resistor cables.
➐ Route the DB resistor cables through the grommeted hole in the resistor mounting panel. Connect to connection
bars DBR
& A2/S1 at the top of the 1397 drive using the (2) M10 hex bolts, washers and KEP nuts supplied
with the kit. Torque to 23.00 N-m (200 lb.-in.).
➑ Connect the motor series field between S1 & S2.
➒ Verify that the jumper between terminals 3 & 4 at the drive terminal block is installed.
Remove the lockout and reapply power. Refer to 1397-DB-B400L — B600L Dynamic Brake Kit
Operation above and proceed to Setup on the last page.
