Damage to electronic components due to electrostatic discharge
By touching electronic components, you can damage or even destroy the inverter through electrostatic discharge (ESD).
• Observe the ESD safety regulations when working on the device.
• Wear suitable personal protective equipment for all work on the device.
• Discharge electrostatic charge by touching uncoated, grounded enclosure parts (e.g. near the grounding
connection on the doors). Only then is it safe to touch electronic components.
Damage to the devices due to dust or moisture penetration
Dust or moisture penetration can damage the Sunny Central or impair its functionality.
• Do not open the Sunny Central during rainfall or humidity of more than 95%.
• Only service the Sunny Central when the environment is dry and free of dust.
• Do not operate the Sunny Central with the door open.
• Switch on the circuit breaker for external supply voltage. This will activate the heating element and internal fans so
that they can switch on automatically.
• Mount all panels of the Sunny Central when maintenance work is interrupted.
• Close and lock the Sunny Central after interrupting or completing maintenance work.
