• A relay output is available at the terminal strip (see chapter 6, item „M“). The relay is

activated when the upper threshold 2 (see chapter 9 c) is exceeded (red LED lights up).
The relay therefore works as a NO contact (NO = „normally open“ = closer contact).

The two other terminals can be used for power supply if you do not wish to connect the
included mains adapter.

¼

Only a stabilised direct voltage of 6 V/DC must be used, and a minimum current of
300 mA must be available (terminal „GND“ for minus/-, terminal „6 V/DC“ for plus/+).

See the bottom of the PCB for terminal contact labels.

The bottom plate has the apertures for installing the connection cables.

• To close the casing, first attach the front to the bottom plate at the bottom.

Carefully fold up the front and fasten it with the screw removed initially.

 meter to the mains voltage.

The RJ45 connection (see chapter 7, item „K“) must not be used. The
connection is only intended for the manufacturer.
