Requirements for signal cables for backup operation, MFR, and fast stop

The cable length and quality affect the quality of the signal. Observe the following cable requirements:

  • Conductor type: copper wire

  • The conductors must be solid or stranded wire.

  • Maximum cable length within the inverter: 260 mm

  • Conductor cross-section: 0.2 mm² to 1.5 mm²

  • External outer diameter: max. 9 mm

  • Insulation stripping length: 6 mm

  • Nominal voltage: at least 600 V

  • Maximum length of conductors: 30 m

  • The cable type and cable-laying method must be appropriate for the application and location.
