LD5157A10 – 10 Ft.
LD5157A20 – 20 Ft.
LD5157A30 – 30 Ft.

Note: Baldor controls with an “E” or “W” suffix have an internal dynamic braking
transistor and resistor installed. If you are installing a larger DB resistor , be
sure to disconnect the internal resistor wires from terminals B+/R1and R2.
These factory installed wires must be removed and the ends insulated with
electrical tape to prevent contact with other components. Failure to
disconnect the internal resistor may result in equipment damage.
