High Current Connections
Three tin-plated solid copper bus bars are provided for high current connections to the battery (B+ and

provides the capture nuts required for the M8 bolts. The maximum bolt insertion depth below the surface
of the bus bar is 1.3 cm (1/2"). Bolt shafts exceeding this length may damage the controller. The torque
applied to the bolts should not exceed 16.3 N·m (12 ft-lbs). Two 1/4" quick connect terminals (S1 and S2)
are provided for the connections to the motor field winding.
