When you install power and signal cables in the terminal blocks, only use cables that meet
the required specification for the safe and reliable operation of the product. Refer to the
following information to assist you with cable selection.
• Wherever possible use cables with the largest cross-sectional area for mains power wiring,
to ensure that voltage drop does not exceed 2%.
• Use copper cables rated for 600 V, 75 ℃ for power terminal wiring.
• Use copper cables rated for 300 V, 75 ℃ for control terminal wiring.
• The inverters in the range between 15 and 90 kW must be grounded conveniently with
fixed connections.
• The inverters in the range between 5,5kW and 11kW must be grounded with and
industrial connector according to IEC 60309.
• The minimum size of the protective earthing conductor shall comply with the local safety
