3.2 Safety Precautions
Please 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 damage.
• 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 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 power company operating the grid into which your plant feeds.
Data Security
• You can connect the Sunny WebBox to the Internet. However, connecting to the Internet entails
a security risk. SMA recommends changing the login password after the initial installation in
order to protect it from unauthorized access by third parties. Select a number-letter combination
with at least 8 characters for your password (see section 10.5.1”Password Quality”
(page63)).
