It carries two STO signal paths, each terminated to a separate M8 4-pin connector — one female, one male — so the safety circuit can be daisy-chained or looped back through the drive without a separate junction box. The kit includes one sealing insert and one insert with connectors, ready for panel-side wiring. ## What the STO connection means for the line Two STO signals means this insert supports dual-channel safety architecture — the standard for SIL 3 / PL e circuits where a single fault must not lead to loss of the safety function. Each M8 4-pin connector carries the 24 VDC signal pair and the return, so the drive's STO inputs are isolated from the safety relay or PLC output. In a Lexium integrated drive application (a compact servo or motor-drive combo), this insert replaces the need to hard-wire into the drive's main control connector, keeping the safety wiring segregated and serviceable.","metaTitle":"Schneider Electric VW3L40020 STO Insert, Lexium Integrated D","metaDescription":"Active production VW3L40020 insert for Lexium integrated drives. 2 STO signals via M8 4-pin connectors.
