Siemens SINAMICS S220

WARNING
High leakage currents when the protective conductor in the line supply cable is
interrupted
The drive components conduct a high leakage current via the protective conductor. Touching
conductive parts when the protective conductor is interrupted can result in death or serious
injury.
• Carefully comply with the applicable regulations when dimensioning the protective
conductor. More detailed information on this is provided in Chapter "Protective connection
and function equipotential bonding (Page69)".
WARNING
Electric shock due to improper DC link connection
Incorrect connections can cause overheating and so 󹪝re and smoke development. There is also
a risk of an electric shock. This can result in serious injury or death.
• When connecting to the DC link, only use the DC link adapter that has been approved by
Siemens.
WARNING
Electric shock due to missing DC link side covers
Live parts are exposed if the DC link side covers are not 󹪝tted. Contact with these live parts could
cause an electric shock.
• Mount the side covers on the 󹪝rst and last component in the drive line-up.
• Order any missing side covers (Article number: 6SL3162-5AA00-0AA0).
WARNING
Fire due to overheating resulting from power cables with inadequate cable cross-sections
Power cables with excessively low cross-sections can cause them to overheat. This can result in
severe injury or death due to 󹪝re and smoke.
• Only use power cables with su󹪟ciently large cross-sections. Take into account the routing
type, ambient temperature and cable length.
WARNING
Fire due to overheating when the total length of the power cables is exceeded
Overheating can result when the total length of the power cables is exceeded. This can result
in severe injury or death due to 󹪝re and smoke.
• Ensure that the total length of all power cables (motor supply cable, DC link cable) does not
exceed the maximum permissible total cable length described in this documentation.
