Warning and
Safety Instructions
Signum scales comply with the
European Council Directives as well
as international regulations and
standards for electrical equipment,
electromagnetic compatibility, and the
stipulated safety requirements.
§ Read these operating instructions
thoroughly before using your device.
That way you will prevent damage to
the equipment.
! Do not use this equipment in hazardous
areas.
! The indicator may only be opened by
authorized service technicians who
have been trained by Sartorius and who
follow Sartorius’ standard operating
procedures for maintenance and repair
work.
! Make absolutely sure to unplug the
indicator from power before you
connect or disconnect any electronic
peripheral devices to or from the
interface port.
! If you use electrical equipment in
installations and under ambient
conditions requiring higher safety
standards, you must comply with the
provisions as specified in the applicable
regulations for installation in your
country.
! The display value can be affected by
extreme electromagnetic influences.
Once the disturbance has ceased,
the instrument can be used again in
accordance with its intended purpose.
– Warning when using pre-wired RS-232
connecting cables: RS-232 cables
purchased from other manufacturers
often have pin assignments that are
incompatible with Sartorius products.
Be sure to check the pin assignments
against the chart in this manual before
connecting the cable, and disconnect
any lines identified differently from
those specified by Sartorius.
– Use only extension cords that meet
the applicable standards and have a
protective grounding conductor.
– Disconnecting the ground conductor
is prohibited.
– Note on Installation:
The operator shall be responsible for
any modifications to the equipment
and for any connections of cables or
equipment not supplied by Sartorius
and must check and, if necessary,
correct these modifications and
connections.
Information on operational quality is
available on request from Sartorius
(in line with norms pertaining to
immunity).
$ If there is visible damage to the
equipment or power cord: unplug the
equipment and lock it in a secure place
to ensure that it cannot be used for the
time being.
IP Rating
– All models are rated to IP43
– Only connect Sartorius accessories and
options, as these are optimally designed
for use with your Signum scale.
$ Do not unnecessarily expose the device
to aggressive chemical vapors or to
extreme temperatures, moisture, shocks,
or vibration.
– Only clean the device as stipulated in
the cleaning instructions: see “Care and
Maintenance."
$ If you have any problems with your
Signum scale:
contact your local Sartorius office,
dealer or service center.
IP Protection:
– The protection rating for the display
and control unit is ensured only if
the rubber gasket is installed and all
connections are fastened securely
(including the caps on unused sockets).
Weighing platforms and equipment
must be installed and tested by a
certified technician.
– If you install an interface port or
battery connector after setting up
your Signum, keep the protective
cap(s) in a safe place to be used for
protecting the interface port or battery
connector when not in use, or prior to
shipment. Do not leave the interface
port uncovered. If you are not using a
particular connector, replace the cap to
protect the data interface from vapors,
moisture and dust or dirt.
Using the Equipment in Legal
Metrology:
– If the scale is to be verified, make sure
to observe the applicable regulations
regarding verification.
– If any of the verification seals are
damaged, make sure to observe the
national regulations and standards
applicable in your country in such
cases. In some countries, the equipment
must be re-verified.
