Indications for laying connection cables:
• The shielding cover must be greater than 70%
• Do not lay power and signal cables side by side, in particular not close to the power filter, and make sure they are physically
separate
• Avoid crossing power cables with signal cables if they are not in the same cable (for example for DR2020)
• Make sure no loops form in the cables. Keep the cables as short as possible and close the common potential correctly
• Keep the input power supply cables separate from those of the output power (for the DR2020)

Note: the DR2020 normally installed externally to the panel must not be considered in the thermal calculation of
the panel itself.
