The 3ADT218587S0113: The 73 dB(A) sound level is the in-service noise emission at rated load. If the converter sits in a quiet control room or near operator stations, factor in acoustic enclosure treatment or remote mounting. The IP00 rating on auxiliary terminals (per IEC 60529, IEC 60947-1, EN 60529) means those terminals are unprotected against solid objects and moisture — the converter must be installed inside a suitable cabinet with at least IP54 to keep dust and conductive debris off the control wiring. Three analog inputs and two analog outputs are available. The 50 Hz line frequency is fixed.
Installation and compliance notes
Operating humidity range of 5 to 95% RH covers most indoor industrial environments. Mount the converter close to the line entry to keep DC bus inductance low.
