Attention
Servo drives including STO-SBC module shall be used only in Pollution Degree environments class PD 2 according to IEC 61800-5-1: During normal operation only non-conductive pollution may occur, temporarily occurring conductivity caused by condensation may only be expected when the servo drive is out of operation.
