What These Instructions Contain
Specifications
Installation
These instructions and any accompanying instructions contain the
necessary information to assemble
install an Open Chassis 1397
&
Dynamic Brake. Each kit may be used with one or more of the 1397
drive HP ratings described on the previous page. For additional
information on wire recommendations, brake parameters and related
function blocks, refer to the 1397 User Manual.

Mounting Requirements For 1397-DB-A001L-A150L and 1397-B003L-B300L kits, DB
(3) repetitive stops with an average of (1) stop every (10) minutes.
DC Power Supplied from 1397 Drive for all ratings.
For 1.5-300HP drive ratings, 120VAC customer supplied power
required for separate DB contactor operation.
For 400-600HP drive ratings, DB uses drive contactor.
IP00 (Open).
contactor must be mounted in the vertical position.
For 1397-DB-B400L-B600L kits, DB uses drive contactor.
All other DB components may be mounted as required.
ATTENTION: Electric Shock can cause injury or death.
Remove all power before working on this product.
!
The drive is at line voltage when connected to incoming AC
power. Before proceeding with any installation or
troubleshooting activity, disconnect, lockout and tag all
incoming power to the drive. Verify with a voltmeter than no
voltage exists at terminals L1, L2 and L3 on the drive input
power terminal block.
Selection
1397-5.15 March, 1999
ATTENTION: Dynamic braking resistors may be
extremely hot. Install in an enclosure or provide adequate
!
clearance to ensure that nothing can come in direct contact
with, or in proximity to the DB resistors. Failure to observe
this precaution can result in severe burns and damage to, or
destruction of, the equipment.
IMPORTANT : The National Electrical Code (NEC) and local
regulations govern the installation and wiring of the dynamic brake.
AC power wiring, DC power wiring, control wiring and conduit must
be chosen and installed in accordance with these codes and the
information supplied in the 1397 User Manual.
All Open Chassis Dynamic Brake kits include a resistor assembly and
an open cage resistor enclosure. Each resistor assembly consists of a
backplate with one or more pairs of resistors mounted in a series or in
a series/parallel configuration.
Dynamic brake kits 1397-DB-A001L — A150L and
1397-DB-B003L — B300L include a DB contactor with (1) contactor
suppressor that mounts across the contactor coil.
Dynamic brake kits 1397-DB-B400L — B600L use the drive
contactor.
1397 Open Chassis Dynamic Brake
What This Option Provides
The DB contactors listed for the following kits require a 120VAC power
supply that will meet the specified continuous and inrush VA values
listed below. To guard against shock hazard, either the open cage
enclosure or an equivalent enclosure must be used to enclose both the
backplate and contactor.

Dynamic Brake Kit Operation
Dynamic braking slows down a rotating DC motor and its load. It is an uncontrolled process. During dynamic
braking, the motor armature is disconnected from the drive. A resistor is placed across the motor’s rotating
armature (now acting as a generator), and the resulting current causes braking torque in the motor. The motor
will decelerate, even with a drive malfunction, as long as motor shunt field excitation is maintained.
The drive must have the DC contactor open for dynamic braking to occur. Dynamic Braking is typically initiated
with a Coast/DB stop command or a drive fault. Under drive fault conditions, the DC contactor opens and applies
the dynamic braking grid across the armature for a dynamic braking stop.

armature (now acting as a generator), and the resulting current causes braking torque in the motor. The motor

When the motor is running normally, the drive’s normally-open M contacts are closed and the normally-closed
M contact is open. When the drive is connected to the motor, the dynamic braking resistor assembly is
disconnected.
