3.1 Power connection
Connection of mains power, motor cable and braking resistor to the SK 700E series of frequency
inverters occurs from below. The structure and the layout of the terminal strip of both versions are
slightly different (frequency inverters up to 22.0 kW and more than 30.0 kW).
Power connection ≤ 22.0 kW Power connection ≥ 30.0 kW
Figure 9: Power connection SK 700E
Compared to the SK 700E (all connections from below), the terminal connections of the SK 5xxE up to
37.0 kW are structured differently. Mains connection to the SK 5xxE frequency inverters occurs from
above, motor and braking resistors connect from below. All terminal connections to inverters of size 8
(≥ 45.0 kW) and higher occur from below, on the frequency inverter front.
