Safety Precautions
The weighing platform is energized by an external industrial-grade AC
adapter. Make sure that the voltage rating printed on this unit is identical to
your local line voltage. If the voltage specified on the label or the plug design
does not match the rating or standard you use, please contact your local
Sartorius dealer or office. To use a main feeder cable from the ceiling or to
mount a CEE plug, you will have to make arrangements inside your facilities for
installation of such cable equipment.
Use only original Sartorius AC adapters/power supplies identified by the
Sartorius label. Use of AC adapters/power supplies from other manufacturers,
even if these units have an approval identification marking from a national
testing laboratory, requires the consent of an authorized Sartorius service
technician.
For detailed information on further options for powering the weighing platform
(e.g., using local low voltage), contact Sartorius headquarters in Germany
or one of the main offices based in your country.
Hook up the weighing platform to the power supply in conformance with the
installation requirements of your country.
Safety Precautions:
A power supply rated to Industrial Class 2 can be plugged into any electrical
outlet without requiring any additional safety precautions. The ground or earth
terminal is connected to the platform housing, which can be additionally
grounded/earthed, if required.
Install the power cable for connection to an isi industrial terminal or a computer
with adequate protection so that the cable cannot get damaged.
Fixed Power Connection:
If the power cable is permanently installed or secured so that it cannot be
unplugged, the weighing platform must be able to be switched off by a
suitable emergency switch. This emergency switch must be installed near the
weighing platform and be within easy reach. In addition, this switch must be
labeled as an emergency switch. All operators must be shown how to operate
this switch.
Operating the Weighing Platform in Zone 2 Hazardous Areas:
If you need to install the platform in Zone 2 hazardous areas, make sure to
comply with the applicable requirements of your country. Installation of
equipment in Zone 2 must be done by a certified technician.The female plug of
the power cable on the industrial-grade power supply must be secured to the
display unit of the weighing platform. The following requirements must be met
for the plug on the other end of the cable:
– either an explosion-protected plug must be installed;
– or the plug must be detached from the power cable and the power cable
permanently secured to a suitable junction box;.
– or the plug must be secured against accidental disconnection
(see Installation Instructions 35751-000-16 AN in this manual).
