What does the C3 EMC filter mean for installation?

C3 (EN 61800-3) is rated for industrial supply networks — the drive connects to a dedicated transformer or industrial distribution, not the public low-voltage grid. If your installation is in a commercial building sharing a mains connection with offices or retail, choose a C2 variant (1AB0 or 1AF0) instead.

What do the coated boards protect against?

The 3C3 coating (IEC 60721-3-3) protects the printed circuit boards against corrosive gases and humidity — essential in water and wastewater treatment plants where hydrogen sulfide and chlorine vapors are present. Standard uncoated drives can fail within months in these environments; the 3C3 coating extends service life significantly.
