while the scale is plugged into the power supply is strictly forbidden. Please
read the installation instructions in the Annex 35751-000-16-A4. To install the
power supply, please follow the installation instructions given in the section
entitled “Connecting the Weighing Platform” in “Getting Started.”
If you will be operating the platform outside the European Community in a
Zone 2 hazardous area, you must comply with the national electrical code and
applicable safety regulations of your country. Please ask your local Sartorius
service technician, office or dealer for information on the currently valid
regulations applicable in your country.
The weighing platform may not be operated in Zone 0, 1, 20 or 21 hazardous
areas, as it does not have an EX approval certificate for these areas.
Any tampering with the weighing platform by anyone, other than installation of
preload devices, will result in forfeiture of all claims under the manufacturer's
warranty.
