General information in order to avoid damage to the device.
• By touching electronic components you can cause damage to or destroy the device through
electrostatic discharge (ESD). Do not touch component connections and plug contacts
unnecessarily. Ground yourself before working on the device.
• With the help of the Sunny WebBox with Bluetooth you can change safety relevant parameters
of the SMA inverters (e.g. SMA Grid Guard parameters). Incorrectly set parameters can
damage or destroy the inverter. Do not alter these safety-relevant parameters without prior
consultation with your electric utility company operating the grid into which your plant feeds.
• The save procedure for parameters can take up to 30 seconds. Do not disconnect the Sunny
WebBox with Bluetooth from the electricity supply during the save procedure. Otherwise data
can be lost.
