2.2 Safety Precautions
General safety precautions in order to avoid physical injury
• Do not open the device or the plug-in power supply.
• Install the cabling in such a way that no one can stand on or trip over it.
General information in order to avoid damage to the device
• By touching electronic components you can damage or destroy the device through electrostatic
discharge (ESD). Avoid touching component connections and plug contacts. Earth 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 configured parameters
can lead to yield losses. Do not alter these safety-relevant parameters without prior consultation
with the electric utility company operating the electricity grid into which your plant feeds.
• The saving procedure for parameters can take up to 30 seconds. Do not disconnect the
Sunny WebBox with Bluetooth from the voltage supply during the saving procedure. If you
disconnect the Sunny WebBox from the voltage supply during the saving procedure, data can
be lost.
