7. Operation

A Supercap condenser is integrated into the energy cost meter, which is used
to operate/program the device without having to plug it into a mains socket (for
min. 30 minutes).
The capacitor is usually in an uncharged state upon delivery/start-up. Therefore,
the energy cost meter can only be operated/programmed when it is plugged di-
rectly into a mains socket upon start-up.
You can unplug the energy cost meter from the mains socket and program it, e.g.
in sufficient light in the living room or office, only when the capacitor is sufficiently
charged (after min. 2 hours).
For energy saving reasons, the display backlight only works when the
energy cost meter is plugged into a mains socket.
If the energy cost meter is operated without plugging it into a mains
socket and the super-cap capacitor becomes empty, the time is lost.
You must then set these again.
Proceed as follows:
• Disconnect any loads that may be connected to the energy cost meter.
• Plug the energy cost meter into an earthed household mains socket (230 V/AC,
50 Hz). On start-up, wait until the normal display appears.
• If the load you want to connect to the energy cost meter has a mains switch,
switch it off.
• Plug the mains plug of the load into the earthed mains socket on the front of
the energy cost meter.
• Switch the load on and wait a few seconds until the energy cost meter shows
the first measured data.
• Before you can use all functions of the energy cost meter, you must first imple-
ment a few settings (e.g. time, electricity tariff).
