3.2 Safety Precautions
Follow all operating and safety precautions in this manual. Failure to follow these instructions could
result in damage to the device and cause personal injury.
General Safety Precautions 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 damage or destroy the device through electrostatic
discharge (ESD). Do not touch component connections and plug contacts. Earth 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
the electric utility company operating the electricity 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 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 10.6.1 "Strength of Passwords" (page 60)).
