Electric shock caused by hazardous voltage when connected to inadequately grounded
line supplies
In the event of a fault, a motor connected to an inadequately grounded line supply can result
in an electric shock, which can lead to death, severe injuries and motor damage.
• Connect motors, as part of the drive system, to TN and TT line systems with a grounded
• Ensure that the SINAMICS devices and motors are compatible with the RCD according to
• For line supplies with grounded line conductor, e.g. TT line systems, use an isolating
• When connected to IT line systems, a monitoring device must signal the first fault between
Electric shock caused by hazardous voltage when testing the insulation resistance
High voltages can be present at the terminals during the measurement and immediately
afterwards, which can cause an electric shock and lead to death or critical injuries if the
terminals are touched.
• Work on electric power installations is only carried out by trained technicians.
• Before you begin measuring the insulation resistance, carefully read the operating manual
• Never touch the terminals when making measurements or immediately after the
• When the line feeder cables are connected, carefully check that the line voltage cannot be
Risk of injury when the converter unintentionally starts
Inadvertent starting of the converter can result in serious or fatal injuries.
• Ensure that the converter is not inadvertently started.
• Attach a warning plate at the location of the switch.
