Safety instructions
Contents of this chapter
The chapter describes the warning symbols used in this manual and refers to the
safety instructions which you must obey when you install or connect an option module.
If you ignore the safety instructions, injury, death or damage can occur. Read this
chapter before you start the installation.
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.
Safety in installation and maintenance
These instructions are for all who install or connect an optional module to a drive,
converter or inverter and need to open its front cover or door to do the work.

Safety instructions 9

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.
• If you are not a qualified electrician, do not do installation or maintenance work.
• Disconnect the drive, converter or inverter from all possible power sources. After
you have disconnected the drive, converter or inverter, always wait for 5 minutes
to let the intermediate circuit capacitors discharge before you continue.
• Disconnect all dangerous voltages connected to other control signal connectors
in reach. For example, it is possible that 230 V AC is connected from outside to a
relay output of the drive, converter or inverter.
• Always use a multimeter to make sure that there are no parts under voltage in
reach. The impedance of the multimeter must be at least 1 Mohm.
