The 3ADT218567S0231: Three analog inputs and two analog outputs are available for speed/torque reference, feedback, or process signals. The unit is designed for 50 Hz line frequency and operates in ambient humidity from 5 to 95% RH non-condensing.
The auxiliary terminals carry an IP00 rating per IEC 60529 and IEC 60947-1 — an open, unprotected connection point. The converter must be installed inside a locked electrical enclosure with a minimum IP54 door. Plan for forced ventilation or a heat exchanger: 82 dB(A) sound level requires ear protection within a few meters during full-load operation.
