Conditions for Installation in Hazardous Locations
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 Minebea Intec , as these are made in accordance
with the restrictions on permissible cable lengths imposed by both the capacitance
and inductivity values (see Control Drawing) 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 transportation, disconnect the equipment from
power and notify your nearest Minebea Intec Service Center.
The weighing platform specifications for Ui, Ii, Pi, Ta, temperature class, Ci and Li are
listed in the enclosed Control Drawing. These parameters (Entity Concept) must be taken
into account when connecting an indicator to the platform.
The explosion-protected weighing system must be installed in accordance with acknowl-
edged rules of engineering. These include national laws and regulations (e.g., National
Electrical Code).
Furthermore, national regulations for accident prevention and environmental protection
must be observed at all times.
Before the platform is operated in a hazardous 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. Determine
whether the installation must be registered with technical inspection authorities 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 Minebea Intec ,
or if the terminal is installed or operated incorrectly, this will result in forfeiture of the
approval for use in the stated hazardous location(s) and of all claims under the manufac-
turer’s warranty.
