For detailed wiring diagrams and resistor selection charts, you should refer to the full BC138 - BC139 DC Control Manual . If you'd like, I can help you:
: Install the drive in a well-ventilated area using its NEMA-1/IP20 metal enclosure. You can reorient the front cover to allow for top or bottom wiring. bc138.rar
: Adjust how quickly the motor reaches full speed or slows down. For detailed wiring diagrams and resistor selection charts,
: The BC138 includes both AC line and armature fusing to prevent damage during catastrophic electrical failures. bc138.rar
: Limits the maximum current to protect the motor from failure or demagnetization. 4. Safety Features
