risk assessment that compares the Safe Torque Off option specifications and all foresee-

3.3.4 Cables and connectors
The STO connector contains the two enable inputs STOA and STOB. Both inputs must
be applied nominal +24VDC in order to energize the motor and make any motor move-
ment possible. STO-signals must originate from a safety isolating transformer in accord-
ance with IEC 61558-1 and IEC 61558-2-6 or from a switch mode power supply with
equivalent property. If only one of the inputs is not applied +24VDC the internal STO
circuit will remove the energy from the motor. The illustration below shows the pinout
of the connector. A 100 mA fuse must be inserted in each channel.
Use only the standard cable for the STO function: JVL stock no. WI1010-M08M4V05P.
