Requirements for signal cables for backup operation, MFR and rapid shutdown initiator

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

  • Conductor type: copper wire

  • Permissible temperature: at least 90°C (194°F)

  • The conductors must be solid or stranded wire.

  • Maximum cable length within the inverter: 260 mm (10.3 in)

  • Conductor cross-section: 0.8 mm² to 1.5 mm² (18 AWG to 16 AWG)

  • Insulation stripping length: 6 mm (0.24 in)

  • Nominal voltage: at least 600 V

  • Maximum length of conductors: 30 m (98 ft)

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