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 repeat the complete safety instructions of the drive but only includes
the instructions related to the scope of this manual.

Safety instructions 7

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. Do not work on the electrical parts of the drive or
the motor before you have isolated the drive system from all power supplies and
made sure by measuring that there is no dangerous voltage present.
WARNING! Always test the operation of the safety circuit according to its
acceptance test procedure at the start-up and after any changes to the safety
circuit.
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 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.
Go through 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.
•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 any 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 multimeter with an impedance greater than 1 Mohm.
• Make sure that the voltage between the drive input power terminals (L1, L2, L3)
and the grounding (PE) busbar is close to 0 V.

• Make sure that the voltage between the drive output terminals (T1/U, T2/V, T3/W)
and the grounding (PE) busbar is close to 0 V.
6. Ask the person in control of the electrical installation work for a permit to work.
