ey to table:
1. The cable diameter indicated in the table are an index for laying the cable in air at max. 40°C,
based on the ÖVN EN 1 and VDE 0100 regulations.
For other ambient conditions and different regulations, the cable diameters must be
adjusted accordingly.
2. Pre-fuses calculated for DOL starting with bypass circuit.
3. The motor cables are designed for the maximum continuous current at an ambient temperature
of 40°C and laid in air. When a bypass circuit is used, the motor cable must be designed for the
value of the pre- or condiut fuses!
The use of NYCY or NYCWY cables for the motor cables (power cables with concentric protection
core) is a low-price alternative to screended cables.
4. In case of a trip, sf fuses protect the inverter from secondary damage in the rectifier, the charging
circuit etc.
The mains fuses represent a secondary protection of the inverter in the case of failure of the
electronic protection. However, if this fuses are blown, a primary defect has already occurred
inside the unit. Therefore, changing
the blown fuses and switching the inverter on again is not
effective. Furthermore, it is not advantageous to use circuit breakers. This has the disadvantage of
a slower switch-off.
5. If the inverter is used without
line choke (CE-DR filter) the fuses must be selected one type higher
to protect the inverter.
