Conditions for Installation
Before putting the equipment into operation, it is important to make sure that the cable
of the power supply is correctly connected to the power outlet (mains supply). All
equipment must be connected to the equipotential bonding conductor via grounding
cable (not included in delivery) connected to the grounding terminals on each device.
The dimensions of the grounding cable are specified in national regulations for electrical
installations. Installation must be performed by a trained technician in accordance with
national regulations and generally acknowledged rules of engineering.
Use only cabling and extensions approved by Sartorius, as these are made in accordance
with the restrictions on permissible cable lengths imposed by both the capacitance and
inductivity values (see the "Annex to EC Type-Examination Certificate" in the operating
instructions) and the requirements for electromagnetic compatibility.
Before putting the weighing system into operation for the first time, make sure there is
no hazard of explosion present at the place of installation. If there is any indication
that the equipment does not function properly (e.g., display remains blank, or no display
backlighting) due to damage during transport, disconnect the equipment from power
and notify your nearest Sartorius Service Center.
The weighing platform specifications for Ui, Li, Pi, Ta, temperature class, Ci, and Li are
listed in the EC type-examination certificate. This certificate also specifies the indicator
models that can be used with these platforms. These specifications must be observed
when connecting an indicator to the platform. Ci and Li values apply to weighing plat-
forms with a 3-m cable for connecting the indicator. (See also the "Certificate
of Proof of Intrinsic Safety" in the appendix to this manual.)
The explosion-protected weighing system must be installed in accordance with acknowl-
edged rules of engineering. These include national and international laws and regula-
tions, such as EN 60079-14 and EN 5281-1-2, for example. In particular, the conditions
described under Item 17 of the KEMA EC type-examination certificate, "Special
Conditions for Safe Use", must be observed. Furthermore, national regulations for acci-
dent prevention and environmental protection must be observed at all times.
Before the platform is operated in a hazardous area/location, it must be inspected either
by a certified electrician or under the guidance and supervision of a certified electrician
to make sure that the weighing system complies with the applicable regulations (in
Germany, Section 12 of the ElexV). Determine whether the installation must be regis-
tered with technical inspection authorities (such as the trade board) in your country.
Regular inspections must also be performed on the system during operation. The system
should be inspected at intervals short enough to permit the prevention or early detection
of defects that arise as a result of normal wear and tear. The longest permissible interval
period is 3 years. Other conditions and standards that regulate the installation and
operation of the equipment and are applicable in your country must be met as well.
When performing inspections, generally acknowledged rules of engineering relevant to
these conditions must also be applied.
If the terminal housing is opened by anyone other than persons authorized by Sartorius,
or if the terminal is installed or operated incorrectly, this will result in forfeiture of
the approval for use in the stated hazardous area(s)/location(s) and of all claims under
the manufacturer's warranty.
