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. They also tell you how to prevent the danger. Notes draw attention to a particular
condition or fact, or give information on a subject.
The manual uses these warning symbols:
WARNING!
Electricity warning tells about hazards from electricity which can cause injury or
death, or damage to the equipment.
WARNING!
General warning tells about conditions other than those caused by electricity, which
can cause injury or death, or damage to the equipment.
WARNING!
Electrostatic sensitive devices warning tells you about the risk of electrostatic
discharge which can cause damage to the equipment.

Instructions for functional safety circuits
This manual does not contain the complete safety instructions of the drive. It only includes
the instructions related to the scope of this manual.
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 or auxiliary
circuits from the power supply. Before you do work on the drive, or its main or
auxiliary circuits, do the steps in section Electrical safety precautions (page 9).
WARNING!
(With permanent magnet or synchronous reluctance [SynRM] motors only)
In case of a multiple IGBT power semiconductor failure, the drive system can produce
an alignment torque which maximally rotates the motor shaft by 180/p(with
permanent magnet motors) or 180/2p(with synchronous reluctance [SynRM] motors)
degrees regardless of the activation of the Safe torque off function. pdenotes the
number of pole pairs.
WARNING!
Do the validation test of the safety function at the start-up and also after you make
changes to the safety circuit.
WARNING!
Make sure that the functional safety of the machine is maintained in situations where
the safety option does not provide protection, for example, during commissioning,
system maintenance, fault tracing, or decommissioning.
WARNING!
Obey 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, commissioning or maintenance work.

Electrical safety precautions
These electrical safety precautions are for all personnel who do work on the drive, motor
cable or motor.
WARNING!
Obey these instructions. 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 begin any 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.
• Open the charging switch if present.
• Open the disconnector of the supply transformer. (The main disconnecting device
in the drive cabinet does not disconnect the voltage from the AC input power
busbars of the drive cabinet.)
• If the drive is equipped with a DC/DC converter unit (optional) or a DC feeder unit
(optional): Open the DC switch-disconnector ([Q11], option +F286 or +F290) of the
unit. Open the disconnecting device of the energy storage connected to the unit
(outside the drive cabinet).
• Open the auxiliary voltage switch-disconnector (if present), and all other possible
disconnecting devices that isolate the drive from dangerous voltage sources.
• In the liquid cooling unit (if present), open the switch-disconnector of the cooling
pumps.
• 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. If the
measurement requires removal or disassembly of shrouding or other cabinet structures,
obey the local laws and regulations applicable to live working (including – but not limited
to – electric shock and arc protection).
•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.
• Make sure that the voltage between the drive output terminals (T1/U, T2/V, T3/W)
and the grounding (PE) busbar is zero.
Safety instructions 9

Important! Repeat the measurement also with the DC voltage setting of the tester.
Measure between each phase and ground. There is a risk of dangerous DC voltage
charging due to leakage capacitances of the motor circuit. This voltage can remain
charged for a long time after the drive power-off. The measurement discharges the
voltage.
• Make sure that the voltage between the drive DC terminals (UDC+ and UDC-) and
the grounding (PE) terminal is zero. In cabinet-built drives, measure between the
drive DC busbars (+ and -) and the grounding (PE) busbar.
WARNING!
The busbars inside the cabinet of liquid-cooled drives are partially coated.
Measurements made through the coating are potentially unreliable, so only
measure at uncoated portions. Note that the coating does not constitute a safe
or touch-proof insulation.
6. Install temporary grounding as required by the local regulations.
7. Ask for a permit to work from the person in control of the electrical installation work.
