According to EN61000-4-4
- partial suppression of EFT/B (Electrical fast transient / Burst) in the power supply (1 kV) and control circuit (0,5 kV), which are switched only by relays (no contactors)
- physical separation of unshielded power supply and communication cables.

According to EN61000-4-5
- cables are well separated, even at short runs. Surge voltages may not exceed 1 kV.
