Safety instructions
Contents of this chapter
The chapter contains the warning symbols used in this manual and the safety
instructions which you must obey when you install or connect an option module to a
drive or inverter. If you ignore the safety instructions, injury, death or damage can
occur. Read this chapter before you start the installation.
Use of warnings
Warnings tell you about conditions which can cause injury or death, or damage to the
equipment. They also tell you how to prevent the danger. The manual uses these
warning symbols:
Electricity warning tells you about hazards from electricity which can cause
injury or death, or damage to the equipment.
General warning tells you about conditions, other than those caused by
electricity, which can cause injury or death, or damage to the equipment.

14 Safety instructions
Electrical safety precautions
These electrical safety precautions are for all personnel who do work on the drive,
motor cable or motor.
This manual does not give detailed information for disconnecting and isolating all
drive types. Refer also to the drive or inverter unit hardware manual.
WARNING! Obey these instructions and the safety instructions of the drive. If
you ignore them, injury or death, or damage to the equipment can occur.
If you are not a qualified electrical professional, do not do installation or
maintenance work. Do these steps before you start installation or
maintenance work.
1. Clearly identify the work location and equipment.
2. Disconnect all possible voltage sources. Make sure that re-connection is not
possible. Lock out and tag out.
• Open the main disconnecting device of the drive.
• If you have a permanent magnet motor connected to the drive, disconnect the
motor from the drive with a safety switch or by other means.
• Disconnect all dangerous external voltages from the control circuits.
• After you disconnect power from the drive, always wait 5 minutes to let the
intermediate circuit capacitors discharge before you continue.
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 quality voltage tester.
• Before and after measuring the installation, verify the operation of the voltage
tester on a known voltage source.
• ACS880 drives:
• Make sure that the voltage between the drive input power terminals (L1, L2,
L3) and the grounding (PE) busbar is zero.
• Make sure that the voltage between the drive output terminals (T1/U, T2/V,
T3/W) and the grounding (PE) busbar is zero.
• Make sure that the voltage between the drive DC terminals and the grounding
(PE) busbar is zero.
• DCS880 drives:
• Make sure that the voltage between drive input phases U1, V1 and W1 and
the frame is zero.
• Make sure that the voltage between terminals C+ and D- and the frame is
zero.

Introduction to the manual
Contents of this chapter
This chapter states exclusion of liability and describes the applicability, compatible
products, supported safety functions, target audience and purpose of the manual.
The chapter also lists contents of this manual, recommended reading as well as
related standards and directives, and explains used definitions, terms and
abbreviations. The safety certificate is included at the end of the chapter.
Exclusion of liability
This manual is an informative aid only. It contains information needed to use the
FSO-21 safety functions module when implementing safety systems. The information
and examples given are for general use only. They do not describe all the necessary
details for implementing a safety system. The manufacturer of the machinery always
remains ultimately responsible for the product safety and compliance with applicable
laws. ABB does not accept any liability for direct or indirect injury or damage caused
by the information contained in this document. ABB hereby disclaims all liabilities that
may result from this document.
Do not open the FSO module, otherwise the safety classification will become invalid
and the warranty cease to be in effect.
Applicability
This manual applies to the FSO-21 safety functions module, revision H.

18 Introduction to the manual
Compatible products
Check the compatibility of the earlier versions with your local ABB representative.
See also section FSO module version handling on page 37.
ACS880 drives and option modules
• ACS880 series without “No FSO support” sticker
• ACS880 primary control program: version 2.21 or later
• FSE-31 pulse encoder interface module: revision D or later
• FENA-21 Ethernet adapter module: version 3.05 or later
• FPNO-21 PROFINET fieldbus adapter module: version 1.00 or later
Application control programs
FSO-21 behavior is independent from application control program, thus all application
control programs are supported by FSO-21. Example applications:
• Machinery control program v2.40 or later
• Crane control program v2.1 or later
• Tower crane control program v1.0 or later
• Winch control program v1.0 or later
• Winder control program v1.10 or later
• PCP/ESP control program (+N5200) v1.1 or later
• PCP/ESP control program SynRM v1.1.1.0 or later
• Spinning control program v1.0 or later
• Rod pump control program v1.0 or later
Note: If you want to use the possibility to switch the motor speed feedback between
encoder and estimate, ACS880 primary control program version 2.51 (or later) and
FSE-31 revision F (or later) are required. See section Motor speed feedback on page
44.
DCS880 drives and option modules
• DCS880 drive modules
• DCS880 firmware, version 2.07 or later
• FSE-31 pulse encoder interface module: revision D or later
• FENA-21 Ethernet adapter module: version 3.11 or later
• FPNO-21 PROFINET fieldbus adapter module: version 1.00 or later
Note that there are fundamental differences how a DCS880 drive operates when
compared to an ACS880 drive. This leads to the following limitations:
• STO takes 500 ms to be achieved in DCS880 drives. Further, a secondary
switching device (i.e. AC-breaker, medium voltage breaker or DC-breaker) must

Introduction to the manual 19
be installed to disconnect the drive from the power grid or from the motor in the
rare case of an internal STO failure. For further information, refer to Supplement
for functional safety (3ADW000452R).
• Safe speed estimate: It is not possible to use the safe speed estimate with a
DCS880 converter. Thus, the FSO-21 module cannot switch to safe speed
estimate in case of an encoder failure but activates the STO function instead.
• For the same reason, speed-dependent safety functions are not available without
a safety encoder (for details see section Safety encoders on page 43). It is
recommended to always use an FSE-31 module with a safety encoder together
with the FSO-21 module.
• Sections in this manual which describe the safe speed estimate or sections which
refer to drive modulating are not applicable to DCS880.
Controller stations
For example the following controller stations are supported. Check the compatibility
of the controller station in its manual.
• ABB AC500-S Safety PLC. For more information, see AC500-S Safety User
Manual (3ADR025091M0207 [English])
• Siemens SIMATIC Fail-safe S7 PLC
Tools
• Drive composer pro PC tool: version 1.8 or later
Note: This manual applies to the Drive composer pro PC tool versions until 1.12. If
you use a later version, the menus and button names can differ from the ones used in
this manual. For more information, see the documentation of the tool.
WARNING! ACS880 drives equipped with the label “No FSO support” are not
compatible with FSO-21. Do not use this combination.
