EXTERNAL RESISTOR ASSEMBLIES
MOUNTING THE DYNAMIC BRAKING MODULE
The diagram to the right illustrates how to mount the DB Module.
The DB Module is compatible with the DIN Rail Mounting Kit option,
or can simply be mounted to a flat surface such as an electrical panel.
NOTE: DO NOT mount the resistors below the Sub-Micro Series
drive! The resistors generate heat, and must be mounted above or to
the side of the drive.
SELECTING EXTERNAL RESISTORS
Use the chart below to select the proper external resistor assembly:
DIN RAIL
BRACKET
DB MODULE
WARNING!
Hazard of electric shock! External resistors are connected to the drive's DC bus, which can reach 950 VDC. Connections to external resistors must be
electrically insulated and mechanically shielded for safety. High Voltage warning signs are also recommended.
!
NOTE: These resistor assemblies are the same as those used with
the Micro Series drives. The DB Module does not include short-
circuit protection for the external resistors. If short-circuit protection
is desired, fusing must be supplied by the customer. Consult Leeson.

PROGRAMMING
1.
Set Parameter 06 (TB-14 OUTPUT) to DB BRAKE (11).
WIRING
The diagram to the right illustrates how the DB module is wired to the SM-Basic drive.
NOTE 1: Use 18 AWG wire for control connections.
NOTE 2: Use minimum 14 AWG wire for connections to B+, B-, R+, and R-. The B+
and B- wires MUST be twisted together and must be less than 12 inches
long. Twisting the R+ and R- wires is also recommended.
NOTE 3: External resistors are required when using Dynamic Braking modules 174417,
174418, and 174419. External resistor assemblies are available from LEESON
(refer to the resistor selection chart below).
