Page 8: Electrical Safety Precautions
8 Safety instructions Only a qualified electrician who has appropriate knowledge on functional, machine, and process safety is allowed to install, start up and maintain the safety circuit. All user-made changes are on the user's responsibility. WARNING! This safety function does not disconnect the voltage of the main and auxiliary circuits from the drive. - Page 9 Safety instructions 9 3. Protect any other energized parts in the work location against contact. 4. Take special precautions when close to bare conductors. 5. Measure that the installation is de-energized. • Use a multimeter with an impedance greater than 1 Mohm. •...

Page 14: Terms And Abbreviations
14 Introduction to the manual Terms and abbreviations Term Description Cat. Classification of the safety-related parts of a control system in respect of their resistance to faults and their subsequent behavior in the fault condition, and which is achieved by the structural arrangement of the parts, fault detection and/or by their reliability. The categories are: B, 1, 2, 3 and 4. -
Page 15: Option Description
Option description 15 Option description Contents of this chapter This chapter describes the option +Q957, prevention of unexpected start-up, and its settings. Overview The Prevention of unexpected start-up (POUS) function disables the control voltage of the power semiconductors of the drive (inverter) output stage. This prevents the drive from generating the torque required to rotate the motor. -
Page 16: Operation Principle
16 Option description Note: Drives with the Emergency stop, stop category 1 function (option +Q952 or +Q964): If the user activates the POUS function during the emergency stop deceleration ramp, it overrides the emergency stop function. This activates the STO function of the drive immediately and the motor coasts to a stop. -
Page 17: Fault Reaction Function
Option description 17 Step Operation Initial status: The drive is in operation and the motor is not running. The user activates the Prevention of unexpected start-up function by switching off the POUS switch [S]. The POUS safety relay [A65] switches off the XSTO inputs IN1 and IN2 of the inverter control unit [A41]. -
Page 18: Hardware Settings
18 Option description • parameter 121.05 Emergency stop source is set to value Inactive. For more information, see the firmware manuals. Hardware settings Appropriate hardware settings have been preset at the factory for the safety function. The settings in the POUS safety relay [A65] are: •... -
Page 19: Electrical Installation
Electrical installation 19 Electrical installation Contents of this chapter This chapter describes the wiring of the safety option done at the factory and contains guidelines for making user connections (if any). 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. -

Page 27: Fault Tracing
If STO hardware failure (5090) is generated, check STO wiring against the circuit diagrams. See drive hardware manual for more information. For more fault tracing possibilities, see the hardware and firmware manuals of the drive. Reporting problems and failures related to safety functions Contact ABB. -
Page 29: Maintenance
If you change any wiring or component after the start-up or restore parameters to their factory default values: • Use only ABB-approved spare parts. • Register the change to the change log for the safety circuit. •... -
Page 30: Competence
30 Maintenance The person responsible for the design of the complete safety system should also note the Recommendation of Use CNB/M/11.050 published by the European co-ordination of Notified Bodies for Machinery concerning dual-channel safety-related systems with electromechanical outputs: • When the safety integrity requirement for the safety function is SIL 3 or PL e (cat. 3 or 4), the proof test for the function must be performed at least every month. -
