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

through electrostatic discharge.
• Earth yourself before touching any components.

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).

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.
