Safety instructions for Power Modules

Electric shock when connecting an unsuitable power supply
If a power supply is connected that is not suitable, parts and components of the device
could be live (under voltage). When touched, hazardous voltages at the housing can result
in severe injury or death.
• Only use the intended supply voltage to operate the Power Modules.
Electric shock caused by high leakage currents when the protective conductor in the line
feeder cable is interrupted
Drive components conduct high discharge currents 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
Note
Fault protection when insulation fails in the motor circuit at the output side
In case of insulation failure in the motor circuit, the overcurrent trip meets the requirements
of IEC 60364-4-41:2005/AMD1:2017 Section 411, Annex D for protection against electric
shock.
• Observe the installation specifications provided in this manual.
• Ensure the continuity of the protective conductor.
• Observe the applicable installation standards.
Note
Malfunctions on non-Siemens equipment caused by high-frequency faults in residential
environments
In the first environment, Category C2 according to EMC product standard IEC 61800-3
(residential, commercial and industrial sector), the device may cause high-frequency
disturbance, which can result in malfunctions in other equipment.
• Have qualified personnel carry out the installation and commissioning with suitable
interference suppression measures.
Note
For a UL-approved system use UL-approved cables only.
