Safety instructions for Active Interface Modules

Danger to life if the fundamental safety instructions and remaining risks are not carefully
observed
If the fundamental safety instructions and remaining risks in Chapter 1 (Page 27) are not
observed, accidents involving severe injuries or death may occur.
• Adhere to the fundamental safety instructions.
• When assessing the risk, take into account residual risks.
Danger to life through electric shock due to the residual charge of the filter capacitors
Because of the filter capacitors, a hazardous voltage is present for up to 5 minutes after the
power supply has been switched off.
Contact with live parts can result in death or serious injury.
• Do not open the protective cover of an AIM 80 kW and AIM 120 kW until 5 minutes have
• Always measure the voltage at the line and load connecting terminals before starting
Danger to life through electric shock due to unconnected cable shields
Hazardous touch voltages can occur through capacitive cross-coupling due to unconnected
cable shields.
• Connect cable shields and the conductors of power cables that are not used (e.g. brake
Danger to life caused by high leakage currents when the protective conductor in the line
feeder 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 for dimensioning the protective
