FIGURE 4. Contactor Wiring Diagram
The contactor coil must be connected to a digital output configured to activate when “No MOSFET Failure”.
The controller will automatically deactivate the coil if the output is expected to be off and battery current of 1A
or more is measured for more than 0.5s. This circuit will not protect against other sources of failure such as
those described in the “Important Safety Disclaimer” on page 3.
Controller Mounting
During motor operation, the controller will generate heat that must be evacuated. The published amps rating
can only be fully achieved if adequate cooling is provided. Good conduction cooling can be achieved by having
the bottom surface of the case making direct contact with a metallic surface (chassis, cabinet). The mounting
has to be like that, so that the thermal-safety limits are not exceeded.
Hall Sensors Connection
Connection to the Hall Sensors is done using a special connector on the front side of the controller. The Hall
sensor connector is a 6-pin Molex Microfit 3.0, ref. 43645-0600. Pin assignment is in the table below.
