NOTE
Operation with single phase supply is possible, with 50% derating of the output current capacity.
The maximum motor cable length stated applies to using a shielded motor cable. When using an unshielded cable, the maximum
cable length limit may be increased by 50%. Maximum cable length may be increased by 100% by using an output choke.
PWM output switching from any inverter when used with a long motor cable length can cause an increase in the voltage at the
motor terminals, depending on the motor cable length and inductance. The rise time and peak voltage can affect the service life
of the motor. Beijer recommend using output choke for motor cable lengths of 50m or more to ensure good motor service life.
For UL compliant installation, use Copper wire with a minimum insulation temperature rating of 70°C, UL Class CC or Class J Fuses
200* and 250* is with 4% input Line choke.
The data above is provided to show typical values. Results measured at the point of installation may
vary according to the installation site and load conditions Test results are measured under 230- or
400-Volt RMS AC Supply Voltage, Operating IE2 motor with matching power rating according to
the drive and Operated at full rated output current capacity. All recommended sizes of cable sizes
and fuses are recommendations. National laws and recommendations are to be considered.
Recommended choice of cable sizes and fuses follows DIN VDE 0100 paragraph 430 Appendix,
motor cable is copper, way of wiring A1 and E is following SS 424 24 24 edition. A1 means cable/
conductors in some kind of duct in a maximum temperature of 40°C. E means cable/ conductors
mounted on a ladder. Calculated at 30°C with 9 or several cables (correction factor 0,78).
