Page 7: Introduction To The Manual
This chapter describes the manual in short and gives some general information for the reader. The chapter also contains a quick reference for implementing a safety system. Applicability The manual applies to ACS880-07/17/37 drives which have the option: Prevention of unexpected start-up (option +Q957). Safety instructions Only a qualified electrician who has appropriate knowledge on functional/machine/process safety is allowed to install, start up and maintain the safety circuit. -
Page 8: Target Audience
8 Introduction to the manual WARNING! Frames nxDXT + nxR8i: The Safe torque off functionality is only achieved through the XSTO connector of the inverter control unit. True Safe torque off functionality is not achieved through the XSTO connectors of the supply control unit. -
Page 9: Abbreviations
EN/IEC 62061 Exclusion of liability ABB is not responsible for the implementation, verification and validation of the overall safety system. It is the responsibility of the system integrator (or other party) who is responsible for the overall system and system safety. -
Page 10: Quick Reference Guide For Implementing A Safety System
If you select EN/IEC 62061 or IEC 61511, make a safety plan. See EN/IEC 62061 or IEC 61511. Assess safety: analyze and evaluate risks (estimate SIL/PL) and define risk reduction strategies. Define the safety requirements. Design the safety system. The part of the design made by ABB is described in chapter Option description and instructions on page 11. -

Option description and instructions 11 Option description and instructions Contents this chapter This chapter describes the +Q957 Prevention of unexpected start-up option and instructs how to wire, start up, test, validate, use and maintain it. The safety data is also given. Overview The Prevention of unexpected start -up (POUS) function disables the control voltage of the power semiconductors of the drive (inverter) output stage. - Page 12 For more information on the emergency stop function, see the appropriate user’s manual. Note: ACS880-07 drives, frames nxDXT + nxR8i with a main contactor/breaker (option +F250/+F255), ACS880-17/37 drives, frames nxR8i + nxR8i, and ACS880-17/37 drives, frames R8 and R11: When the STO function is activated in the inverter unit, the main contactor/breaker is opened after a user-defined delay (defined with parameter 94.11, the...

Page 15: Wiring
Option description and instructions 15 Wiring The operating switch and the indication lamp for the POUS function are not factory- installed. The user must install and wire them to the drive on site. There are double contacts in the POUS switch [Sxx] and double wiring (two-channel connection) between the button and the POUS safety relay [A65]. -
Page 16: Start-Up And Acceptance Test
16 Option description and instructions Start-up and acceptance test You need the Drive composer PC tool or a control panel to perform the start-up and acceptance test. Initial status: Make sure that the drive is ready for use, that is, you have done the tasks of the drive start-up procedure. - Page 17 Option description and instructions 17 Action Switch off the drive start signal. If a fault message is generated, reset the drive. See section POUS indications on page 18. Restart the drive and motor and check that they operate normally. Fill in and sign the acceptance test report which verifies that the safety function is safe and accepted to operation.

Page 19: Proof Test Interval
Option description and instructions 19 Proof test interval After the operation of the safety function is validated at start-up, the safety function must be maintained by periodic proof testing. In high demand mode of operation, the maximum proof test interval is 20 years. In low demand mode of operation, the maximum proof test interval is 2 or 5 years (high or low demand as defined in IEC 61508, EN/IEC 62061 and EN ISO 13849-1). -

For the environmental limits for the safety functions and the drive, refer to the hardware manual. ACS880-07 drives, frames R6 to R11 The maximum ambient temperature for the drive with safety relays is 45 °C (113 °F). In the temperature range +40…45 °C (+104…113 °F), the rated output current must be derated by 2% for every added 1 °C (1.8 °F). -
