4.7.2: MTO Wiring Overview
This diagram gives detail on the physical cabling, shielding, and grounding of the wiring between
the drive MTO inputs and the machine level safety circuits. Note that the diagram shows the SPD,
but it is not required if mains voltage is supplied through an isolation transformer.
4.7.3: MTO Power Requirements
The 24V power supply for the MTO inputs must be SELV or PELV rated.
The 24V power supply for the drive control power must be SELV or PELV rated.
4.7.4: MTO Wiring Requirements
Electrical connections to the MTO inputs should follow the requirements for fault exclusions for
short circuits between conductors and short circuits between conductors and other conductive
parts or earth or the protective bonding conductor.
These requirements are given in ISO 13849-2 and IEC 61800-5-2:2016 for reference only.
