Environmental and protection ratings
The 3ADT218566S0134: The auxiliary terminals carry an IP00 protection rating per IEC 60529 and IEC 60947-1, meaning they are not protected against solid objects or moisture — the converter must be installed inside a suitable enclosure. Operating humidity range is 5 to 95 % RH, non-condensing, which covers most industrial environments without derating.
Acoustic noise and I/O
Sound pressure level is rated at 82 dB(A), typical for a forced-air-cooled converter of this power class — factor this into cabinet acoustic design if the drive is near operator stations. The unit includes 3 analog inputs and 2 analog outputs, sufficient for speed reference, torque limit, and process feedback loops.
