Installation

Contents of this chapter

This chapter describes the installation procedure, wiring and allowed cable type of the

Safe torque off function.

Supply voltage

WARNING! The supply voltage of the STO circuit (ASTO boards) is 24 V DC.

Never supply the ASTO board with 230 V AC or 115 V AC. This can damage the

board and it must be replaced.

Note: Since former option +Q950 (Prevention of unexpected start-up function) uses 230 V

or 115 V supply voltage, it is not possible to use it with Safe torque off function (option

+Q967) or vice versa. Note this when using spare parts.

Note: The Safe torque off function can be installed afterwards (that is, after the factory

assembly) to drive modules. Contact ABB Drives Service for further information.

Connections

 STO input

The STO input can be supplied from an external power supply or from an RMIO control

unit 24 V DC output. In both cases the requirements given below must be fulfilled.
