3.2 Safety Instructions
Follow all operating and safety instructions in this manual. Failure to follow these instructions could
result in damage to the device and cause personal injury.
General safety instructions, in order to avoid physical injury.
• Never open the plug-in power supply.
• Install the cabling in such a way that no one can stand on or trip over it.
• The Sunny WebBox is only to be operated using the supplied plug-in power supply and in the
voltage range intended for this.
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 you can change the safety-relevant parameters of 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.
Data Security
• The Sunny WebBox can be connected to the Internet. However, connecting to the Internet
entails a security risk. SMA Solar Technology AG recommends that you change the login
password after the initial installation in order to prevent unauthorized access by third parties.
Select a number-letter combination with at least 8 characters for your password (see section
10.5.1"Strength of Passwords" (page66)).
