2. Connecting the demonstration case to the mains
supply
Prior to connection of the demonstration case to the mains voltage, the user must check the
following:
• The supplying mains socket is provided with a PE connection and no mechanical damages have
been detected at the mains socket.
• No damages have been detected at the demonstration case and at the mains supply line.
• The supplying mains socket is protected by means of a RCD (IΔN = 30 mA).
