7.4 Connection of Unit
7.4.1 Dimensioning of conductor cross-section
The connecting cables must be protected externally, considering the maximum voltage and maximum
current values of the fuses. The line fuses and cable cross-sections must be dimensioned according to
EN 602041 and DIN VDE 0298 Part 4 for the nominal operating point of the frequency inverter.
HINWEIS
The fuses must be chosen depending on the individual application. The values
recommended in the technical Data apply for the continuos rated operation without
overload.
The cable dimensions should be selected according to the current load and voltage drop to be
expected. Select the cable cross-section of the cables such that the voltage drop is as small as
possible. If the voltage drop is too great, the motor will not reach its full torque. Also comply with any
additional national and application-specific regulations and the separate UL instructions. For typical
mains fuses, refer to chapter 5 "Technical data".
According to EN61800-5-1, the cross-sections of the PE conductor shall be dimensioned as follows:
Mains cable
Protective conductor
Mains cable up to 10 mm²
Install two protective conductors of the same size as the mains
cable, or one protective conductor of a size of 10 mm².
Mains cable 10…16 mm²
Install one protective conductor of the same size as the mains
feeder.
Mains cable 16…35 mm²
Install one protective conductor of a size of 16 mm².
Mains cable > 35 mm²
Install one protective conductor of half the size of the mains feeder.
The following tables provide an overview of typical cable cross-sections (copper cable with PVC
insulation, 30 °C ambient temperature, continuous mains current max. 100% rated input current,
installation variant C). Actual mains cable cross-section requirements may deviate from these values
depending on actual operating conditions.
7.4.1.1 Typical cross-sections Size 1 through 7 (0.25 kW … 132 kW)
The following tables provide an overview of typical cable cross-sections (copper cable with PVC
insulation, 30 °C ambient temperature, continuous mains current max. 100% rated input current,
installation variant B2). Actual mains cable cross-section requirements may deviate from these values
depending on actual operating conditions.
230 V: One-phase (L/N) and two-phase (L1/L2) connection
