Note concerning motor connection
The following main factors must be taken into consideration for connecting motors to
the 8230 frequency inverter:
•
8230 frequency inverter unit type: As standard the response threshold for earth
fault detection on the motor side is 10 % I
N
.
•
8230 frequency inverter pulse frequency
•
Motor insulation system: Details from the motor manufacturer concerning the max.
motor voltage/current in the motor terminal box, suitability for inverter operation
•
Cable type: Screened, with armouring or without screen
•
Effective cable length: Parallel cables, group supply
•
Cable cross-section: Voltage drop
≤
1.75 % or
≤
3 %
Suitable screened heavy current cable 0.6/1 kV
