• Establish all electrical connections according to the circuit diagram.
• Safely store the documentation within the immediate area of the inverter. It must be accessible
to service and maintenance personnel at all times.
Electrostatic discharge can damage electronic components
Electrostatic discharge can destroy components.
• During work on the inverter and handling of the components, observe the ESD protection
regulations and wear protective gloves.
• Discharge electrostatic charges through contact with unvarnished, grounded enclosure parts
(e.g., on the PE connection of the doors). Only then it is safe to touch any electronic components.
Burns
Some components, such as fuses, can become hot during operation.
• Wear safety gloves when working on the inverter.
Inverter Damage
Tampering with the device may result in plant damage.
• Do not operate the inverter while the door is open.
If the key remains in the door lock, the inverter can be opened by unauthorized persons.

Electrostatic discharge can destroy components.
• During work on the inverter and handling of the components, observe the ESD protection
regulations and wear protective gloves.
• Discharge electrostatic charges through contact with unvarnished, grounded enclosure parts
(e.g., on the PE connection of the doors). Only then it is safe to touch any electronic components.
Only operate the Sunny Central in regions with a radio frequency band of 80 MHz … 1 000 MHz.
Warning signs must be easily readable at all times and must be replaced in the event of damage.
