Safety instructions 9 Safety instructions Contents of this chapter This chapter contains the safety instructions which you must obey when you install, operate and do maintenance on the safety functions of a drive. Use of warnings and notes Warnings tell you about conditions which can cause injury or death, or damage to the equipment.
10 Safety instructions Only a qualified electrical professional who has sufficient knowledge about functional, machine, and process safety is permitted to install, start up and maintain the safety circuit. All user-made changes are on the user's responsibility. WARNING! The safety function described in this manual does not isolate the main circuit or auxiliary circuit from the power supply.

Safety instructions 11 5. Measure that the installation is de-energized. • Before and after measuring the installation, verify the operation of the voltage tester on a known voltage source. • Make sure that the voltage between the drive input power terminals (L1, L2, L3) and the grounding (PE) busbar is zero.
The manual is applicable to ACS880-07/07LC/17/17LC/37/37LC drives which have the option: Emergency stop, stop category 1 with main contactor/breaker, with safety relays (option +Q952). For the option +Q952, ABB installs the FIO-01 digital I/O extension module (option +L501) to the drive. Target audience The manual is intended for people who install, start up, use and service the safety function.

Then, the drive opens the main contactor/breaker, which disconnects the input power from the drive. For the option +Q952, ABB installs the FIO-01 digital I/O extension module (option +L501) to the drive control board (Slot 1).
The figures show a simplified operation principle. Implementation of main contactor/breaker and charging circuit can vary depending on the product.

The emergency stop safety relay [A61] de-energizes the digital input on the digital I/O extension module [A412.X] of the inverter unit.
26 Option description Fault reaction function Definition: A safety function requires a “fault reaction function” that tries to initiate a safe state if it detects a failure in the safety system. The fault reaction function of the emergency stop safety relay trips the system, if it detects a failure in the safety circuit (for example, short circuit between signals, open circuit, or redundancy fault).
3. Use shielded, twisted pair cables. ABB recommends double-shielded cable and gold-plated contacts in the emergency stop button. 4. Make sure that the sum resistance for one channel (loop resistance) is not more than 1 kohm.
You can also install additional reset buttons and indication lamps for the emergency stop circuit on site. ABB recommends gold-plated contacts in the reset button. Connect the buttons to the applicable terminal block inside the drive cabinet. See the circuit diagrams delivered with the drive.

42 Maintenance Proof test interval After the operation of the safety function is validated at start-up, the operation of the safety function must be ensured 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 1 year (high or low demand as defined in IEC 61508, IEC/EN 62061 and EN ISO 13849-1).
Safety data values This safety data is valid for the default design of the safety circuit described in this manual. If the final design is different from the default, ABB calculates new safety data and delivers it separately to the customer.
