Safe Torque-off Wiring Requirements

The safe torque-off (STO) connector uses spring tension to secure the wire.
Depress the numbered tab along side each pin to insert or release each wire.
Two rows of pins are provided for drive-to-drive connections. Wire must be
copper with 75 °C (167 °F) minimum rating.
IMPORTANT The National Electrical Code and local electrical codes take precedence over
IMPORTANT Stranded wires must terminate with ferrules to prevent short circuits, per
