Damage to the components due to dust intrusion or moisture penetration
Dust intrusion or moisture penetration can damage the inverter or impair its functionality.
• Do not open the inverter during rainfall or humidity of more than 95%.
• Only maintain the inverter when the environment is dry and free of dust.
• Do not operate the inverter while the door is open.
• If present, connect the external supply voltage after having set up and installed the inverter.
• Switch on the circuit breaker of the external supply voltage as well as the circuit breakers of the 24 V circuits.
This will activate the heating and interior fans, which will then switch on automatically.
• Mount all panels of the inverter when interrupting the installation process or commissioning.
• Close and lock the inverter.
Damage to electronic components due to electrostatic discharge
Electrostatic discharge can damage or destroy electronic components.
• Observe the ESD safety regulations when working on the device.
• Wear Hazard Risk Category 2 personal protective equipment for all work on the devices.
• Discharge electrostatic charge by touching uncoated, grounded enclosure parts, e.g. at the PE connection on the
doors. Only then is it safe to touch any electronic components.
