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 taken into account when connecting an indicator to
the platform.  Ci and Li values apply to weighing platforms 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

acknowledged rules of engineering.  These include national and international
laws and regulations, 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 accident 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 registered 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.
