5. The Braking Transistor Unit and Remote Mount Resistor Unit MUST BE GROUNDED.
Observe the following precautions:
• Ground units per local electrical codes.
• If the installation requires the Remote Mount Resistor Unit to be used without its
enclosure (with grounding terminal), ground it by attaching a ground lead
at one of the mounting screws.
• Grounding resistance of the Braking Transistor Unit should be 100 ohms or less.

Fuse required only if UL/CUL certification is needed. See separate instruction sheet
02Y00025-0393 for details.
