2.3 Skills of Qualified Persons
The tasks described in this document must be performed by qualified persons only. Qualified persons must have the
following skills:
• Knowledge of how a Sunny Central works and is operated
• Training in how to deal with the dangers and risks associated with installing and using electrical devices and systems
• Training in the installation and commissioning of electrical devices and systems
• Knowledge of all applicable standards and directives
• Knowledge of and adherence to this manual and all safety precautions

Risk of burns due to hot components
Some components of the Sunny Central can get very hot during operation. Touching these components can cause burns.
• Observe the warning messages on the devices.
• During operation, do not touch any components marked with such warnings.
• After disconnecting the PV system from voltage sources, wait until hot components have cooled down sufficiently.
• Wear suitable personal protective equipment for all work on the Sunny Central.

Damage to electronic components due to electrostatic discharge
Electrostatic discharge can damage or destroy electronic components.
• When working on the Sunny Central and handling assemblies, observe all ESD safety regulations.
• 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 Sunny Central due to dust or moisture penetration
Dust intrusion or moisture penetration can damage the Sunny Central or impair the functionality of the Sunny Central.
• Do not open the Sunny Central during rainfall or humidity of more than 95%.
• Only open the Sunny Central when the environment is dry and free of dust.
• Do not operate the Sunny Central with the door open.
Operation failure of the PV system due to incorrectly set parameters
If the parameter settings for grid management services are incorrect, the PV system may not be able to meet the
requirements of grid management services. This can mean that yield losses are incurred and the inverter has to be
disconnected by the grid operator.
• When setting the modes of grid management services, ensure that the control procedures agreed with the grid
operator are parameterized.
• If the PV power plant is operated with a Power Plant Controller, ensure that the mode WCtlCom for active power
limitation and the mode VArCtlCom or PFCtlCom for reactive power control are selected in the Sunny Central.
