Safety in installation and maintenance

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.
• 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. Lock out
and tag out.
• 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 voltage tester to make sure that there are no parts under voltage in
reach. The impedance of the voltage tester must be at least 1 Mohm.
