The compliancy to the standards are intended for a single fan.
No tests have been made on multiple installations.
The EMC tests are conducted without 485 communication wire, analog signals or Bluetooth devices.
WARNING
WARNING
To improve the Electromagnetic compatibility a ferrite should be put on the power supply cable
(close to the driver).
2.3 Surge protection
The drivers installed in the RDP fans incorporate MOV-based surge-protection devices (SPDs) to protect the
electronics from power surges.
These devices fulfil the requirements of the IEC 61000-6-2 and IEC 61000-4-5 standards for surge immunity and
testing: they withstand without damage 1 kV pulses in differential mode, and 2 kV pulses in common mode.
The internally mounted SPD is a Type 3 SPD, in accordance with IEC 61643-11, intended for local protection of
the sensitive electronics. Its design assumes that the power distribution network includes higher-level Type 2
and Type 1 SPDs, where required for protection against lightning strikes, and also against repeating lower-level
power surges, generated by sources inside the local network, like any unfiltered contactors of highly-inductive
loads (e.g. motors and transformers).
Without filtering or protection, regularly repeating differential-mode low-level voltage surges can lead to
permanent damage to the electronics.
Specific electrical safety and EMC standards are applied according to the available models of conformity
declaration (identified as 985732 and 985748):
