2.4 Safety Precautions
Safety-Relevant Parameters
Safety-relevant operating parameters of the inverters in your plant can be changed using the
Power Reducer Box. These parameters may normally only be changed after consultation with the
power supply company into whose electricity grid you are feeding.
• If you have any doubts, contact your power supply company.
Electrostatic Discharge
By touching electronic components, you may cause damage to or destroy the Power Reducer Box
through electrostatic discharge.
• Earth yourself before touching any components.
Data Security
You can connect the Power Reducer Box to the Internet. When accessing via the Internet, there is the
risk that unauthorised users may access and manipulate the data or devices in your plant.
• Take suitable protective measures (e.g. set up a firewall, close network ports that are not
required, only enable remote access via the VPN tunnel).
• After logging in for the first time, change the default password. Select a number-letter
combination with at least eight characters for your password (see Section 10.2 "Changing your
Password", page 53).
• Keep the password secret and prevent unauthorised persons from accessing it.
