Standard
• Integrated mains filter
Class C1 (residential environment) for motor mounting of the frequency inverter,
Class C2 (industrial areas) for wall-mounting with motor cable length up to 5 m
• Low leakage current (< 16 mA)
• Adaptation for operation on IT network by means of jumpers (change of leakage current
possible)
• Consistent and user-friendly parameter structure
• Automatic motor parameter identification
Output frequency
