Requirements for signal cables for backup operation, multifunction relay (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.
- Conductor cross-section: from 0.2 mm2 to 1.5 mm2
- External outer diameter: max. 9 mm
- Insulation stripping length: 8 mm to 10 mm
- Nominal voltage: at least 600 V
- Maximum cable length: 200 m
- UV-resistant for outdoor use
- The cable type and cable-laying method must be appropriate for the application and location.
