Integration Context
The IP20 rating means this drive is intended for installation inside a control cabinet or panel — not for washdown or outdoor placement. The FSB frame size mounts on a standard DIN rail or panel plate, with a 196 mm height leaving room for a gland plate above. The external 24 V supply powers the control logic and the Safe Torque Off circuit; losing that supply drops the drive into a safe state.
