2.9.8 Cable connections
With the cable connections, a differentiation must be made between Size 1 and Size 2 of the SK 750E
frequency inverter. Both have different cable connections for the line input and the output from the frequency
inverter to the motor (see the table below). The cable connections for the control level, control of the brake
resistor and the temperature sensor input are the same for both sizes.
