2.9.8 Cable clamp screws
Some of the cable clamp screws used with SK 750E frequency inverters are different for frame sizes 1 and 2.
The cable entries for the mains input and for the frequency inverter output where the motor is connected are
different (see table below). The two frame sizes are identical however with regard to the cable entries for the
control level, control of the brake resistor and the temperature sensor input.
