Electrostatic discharge
By touching electronic components, you can damage or even destroy the inverter through electrostatic
discharge (ESD).
• When working on the inverter or handling assemblies, observe the electrostatic discharge safety
regulations and wear protective gloves.
• Discharge the electrostatic charge by touching uncoated, earthed enclosure parts (e.g. at the
protective conductor connection on the doors). This makes it safe to touch electronic
components.
Environmental influences
Moisture and dust penetration will damage the inverter.
• Do not open the inverter when it is raining or if humidity is over 95%.
• Only perform maintenance in a dry and dust-free environment.
Observing torque
Adhere to the torque specifications listed in the circuit diagram and installation manual.
• Contact the SMA Service Line if torque specifications are not given.
Storing documentation
This documentation must be accessible to all service and maintenance personnel at all times.
• Safely store this documentation within the immediate area of the inverter.
Warning signs
Warning signs must be clearly legible at all times.
• Replace warning signs if damaged.
