Connecting the Scale to AC Power
The scale is powered by an AC adapter supplied with the scale. Make sure that
the voltage rating printed on this unit is identical to that of your local line voltage.
If the voltage specified on the label or the plug design of the AC adapter do not
match the rating or standard you use, please contact your Sartorius office or dealer.
When you use the scale and associated equipment, you must comply with the
national electrical code and applicable safety regulations of your country.

Hook up the scale to the power supply in conformance with the installation
requirements of your country.
If you use the QC scale in a Zone 2/Class I, Div. 2 hazardous area/location,
make sure to comply with the valid standards and regulations of your country,
applicable to the installation of equipment in a Zone 2/Class I, Div. 2 hazardous
area/location, e.g. in Germany with ElexV from 27.02.1980 (BGBI. I, P.214).
Only authorized technicians are allowed to install the equipment
in a Zone 2/Class I, Div. 2 hazardous area/location.
The female plug of the power cable must be securely fastened to the male socket
on the QC display unit. On the other end of the power cable,
– either an explosion-proof plug-and-socket connection must be installed
– or the plug must be detached from the power cable and the power cable
securely connected to a suitable junction box.
