– The area of use for the PMA7501-Y
model is defined in the type-examination
certificate. All restrictions listed in
the type-examination certificate must
be strictly observed. Operating the
PMA7501-Y model beyond the restric-
tions indicated is not permitted, and
is considered use of the equipment for
other than its intended purpose.
– Unless performed by an authorized
Sartorius technician, any installation work
that does not conform to the instructions
in this manual will result in forfeiture
of all claims under the manufacturer’s
warranty.
– Installation of the PMA7501-Y in a
potentially explosive atmosphere must be
performed by a certified electrician who is
familiar with the assembly, start-up and
operation of both the system and the rel-
evant 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 stain-
less steel screw and nut to connect the
grounding conductor. The wire used for
the grounding conductor should have
a cross-sectional diameter of at least
4 mm
2
and have a suitable ring lug
attached. Connect all equipment, includ-
ing peripheral devices, to the equipoten-
tial bonding conductor.
– Do not expose the scale to extreme
temperatures, aggressive chemical vapors,
moisture, shocks or vibrations.
– 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 informa-
tion 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 the
penetration of solid foreign objects.
For the User
– Always make sure the equipment is
disconnected from AC power before
performing any installation, cleaning,
maintenance or repair work on the scale.
– If you see any indication that the scale
cannot be operated safely (for example,
due to damage), turn it off and lock it in
a secure place or otherwise prevent use
of the equipment for the time being.
– Chemicals (e.g., gases or dusts) that can
corrode and damage the inside or outside
of the device must be kept away from the
equipment.
