- The area of use for the PMA7501-X
model is defined in the type-examination
certificate. All restrictions listed in
the type-examination certificate must
be strictly observed. Operating the
PMA7501-X model beyond the restric-
tions indicated is not permitted, and
is considered use of the equipment for
other than its intended purpose.
Any installation work that does not con-
form to the instructions in this manual
will result in forfeiture of all claims under
the manufacturer’s warranty. If you use
the equipment in a hazardous area out-
side Germany, you must comply with the
national electrical code and safety
regulations applicable in your country
(e.g.: EN60079-14). Ask your supplier
for information on the legal regula-
tions applicable in your country. For the
USA and Canada, please refer to Control
Drawing 35958-000-07-A4.
– If the equipment housing is opened by
anyone other than persons authorized by
Sartorius, this will negate its conformity
with regulations governing its use and
result in forfeiture of all claims under the
manufacturer’s warranty.
– Installation of the PMA7501-X in a
potentially explosive atmosphere must be
performed by a certified electrician who is
familiar with both the assembly, start-up
and operation of both the system and the
relevant guidelines and regulations,
and has the required qualifications for
performing the installation. If you need
assistance, contact your Sartorius dealer
or the Sartorius Service Center.
– Avoid static electricity. Connect an equi-
potential bonding conductor.
Disconnecting equipotential bonding
conductors is not permitted. The bore
hole is marked by a “ground” symbol. If a
bore hole is provided, use a stainless steel
screw and nut to connect the grounding
conductor. The wire used for the ground-
ing conductor should have a cross-sec-
tional diameter of at least 4 mm
2
and have
a suitable ring lug attached. Connect all
equipment, including peripheral devices,
to the equipotential bonding conductor.
– Do not expose the scale to extreme
temperatures, aggressive chemical vapors,
moisture, shocks or vibrations.
Exposure to excessive electromagnetic dis-
turbance can cause the readout value to
change. Once the disturbance has ceased,
the instrument can be used again in
accordance with its intended use.
– The equipment must be used indoors.
– To ensure safety, disconnect the equip-
ment from power before connecting or
disconnecting the cables or electronic
peripheral devices.
– If you use cables purchased from another
manufacturer, check the pin assignments
in the cable against those specified by
Sartorius before connecting the cable to
Sartorius equipment, and disconnect any
wires that are assigned differently.
The operator shall be solely responsible for
any damage or injuries that occur when
using cables not supplied by Sartorius.
– When connecting the scale to the power
supply, the laws valid in your country
must be observed. If you should have any
questions, please contact your supplier or
Sartorius Customer Service for information
on the legal regulations applicable in your
country. The scale must be installed by
a certified technician to avoid forfeiture
of all claims under the manufacturer’s
warranty.
– To avoid generating static electricity
(e.g., when using the in-use dust cover),
connect the equipotential bonding
conductor.
– The equipment is protected against
penetration by solid foreign objects.
