Design including a connector
The connectors of the Lenze system cables are designed in a distinctive, application-specific
fashion (power, fan, feedback, digital frequency).
For the connection of Lenze motors to Lenze controllers, we recommend using Lenze system
cables.
Apply shields of the motor cable to the controller on a large surface.
Design with terminal box

ƒ Keep the terminal box free of foreign matter, dirt, and humidity.
ƒ Observe specified clearances in air between bare, live parts, and to earth.
ƒ The cable glands are designed for the cable cross-sections of the Lenze system cables.
ƒ The system cables are designed for standard cable glands.
ƒ To use other cable cross-sections, extended sizes, reduced sizes, or other types of
cable glands must be used.
ƒ Extensive shielding of motor cable on motor and controller.
