Warning and
Safety Information
Improper use or handling can
result in property damage and/or
personal injury. To prevent damage
to the equipment, read these
operating instructions thoroughly
before using your scale. Keep these
instructions in a safe place.
The manufacturer shall not be held
liable for damage caused by failure
to observe this warning and safety
information or the instructions.
When you use electrical equipment
in installations and under ambient
conditions requiring higher safety
standards, you must comply with the
provisions specified in the applicable
regulations for installation in your
country.
Follow the instructions below
to ensure safe and trouble-free
operation of your scale:
!Make sure that the voltage rating
printed on the power supply is
identical to your local AC power
rating.
– The only way to turn the scale
power off completely is to
disconnect the power supply from
the wall outlet (mains supply).
!Handle the equipment with care
as required by the IP protection
ratings. The environment in
which they are used must also be
protected.
!Protect the power supply as
required by the IP65 standard
(dust-tight and washdown-
resistant).
!The housing of the YPS02-X...
power supply is made of AlMgSi
and should be handled
accordingly.
!Cabling: The casing on the po-
wer cable is made of
– rubber (on models YPS02-Z...,
-XDR, -XKR, -XAS)
– PVC (on model YPS02-XGR)
All other cables connecting
the weighing equipment and
peripheral devices, as well
as the wiring inside the devices,
are cased in PVC materials.
Chemicals that corrode these
materials must be kept away
from these cables.
!Use only cabling and extensions
approved by Sartorius, as these
are made in accordance with
the restrictions on cable lengths
imposed by the capacitance
and inductance (see the attached
certificate of conformity) and the
requirements for electromagnetic
compatibility.
!Factory Series equipment may
only be operated in an ambient
temperature range between
0°C and +40°C (+32°F to
+104°F). Make sure there is
sufficient ventilation to prevent
heat from building up in the
equipment.
!The equipment must be used
indoors only.
!Clean the equipment in
accordance with the instructions
(see the section entitled “Care
and Maintenance”).
!Avoid build-up of static electricity
on the dust cover and in glass
parts (see the section entitled
“Care and Maintenance”).
!Have the equipment inspected
at appropriate intervals for
correct functioning and safety by
a trained technician (for instance,
inspection of the cables for
damage).
!When cleaning your scale,
make sure that no liquid enters
the scale housing; use only a
slightly moistened cloth for
cleaning the scale.
!Using the scale in a network:
No more than 8 scales may
be connected, using a YDI01-Z
Zener barrier, to the RS-485
interface port.
!Make sure all operating
personnel are trained to recog-
nize malfunctions and to take
the appropriate corrective
or preventive measures (such as
disconnecting the equipment
from power).
!The equipment meets the
requirements for electromagnetic
compatibility. Avoid interference
stronger than that allowed for
in the relevant standards (see also
the section entitled “Overview;
Declaration of Conformity” in the
operating instructions).
Do not open the scale housing. If
the seal is broken, the manufacturer’s
warranty becomes null and void.
!If you use the scale in a
hazardous area or location out-
side Germany, you must comply
with the national electrical code
and applicable safety regulations
of your country. Ask your local
Sartorius office or dealer for
information on the legal regula-
tions applicable in your country.
Warning:
!Any tampering with this scale by
anyone other than authorized
persons will result in forfeiture of
the approval for use in the stated
hazardous area/location and
of all claims under the
manufacturer’s warranty.
If you have any trouble with your
scale:
