Safe Torque-off Wiring Requirements
The safe torque-off (STO) connector uses spring tension to secure the wire. Depress the num-
bered tab along side each pin to insert or release each wire. Two rows of pins are provided for
inverter-to-inverter connections. Wire must be copper with 75 °C (167 °F) minimum rating.

IMPORTANT Stranded wires must terminate with ferrules to prevent short
circuits, per table D7 of ISO 13849.
