Sartorius Economy Series Operating Instructions Manual page 6

Follow the instructions below to ensure
safe and trouble-free operation of your
scale:
! Make sure that the voltage rating
printed on the AC adapter or
power supply is identical to your
local AC power rating. Keep in
mind that there may be fluctuations
in the voltage.
– The only way to turn the scale
power off completely is to discon-
nect the AC adapter or power supply
from the wall outlet (mains supply)
! Protect the AC adapter or power
supply as required by the IP rating
(IP40 = protected against ingress
of foreign bodies larger than 1 mm
but not protected against water ;
IP65 = dust-tight and washdown-
resistant)
! The casing on the power cable of
the models 609308-..1 and YPS03-
XGR AC adapters/power supplies is
made of PVC; on the model YPS03-
XDR AC adapter/power supply, the
cable is cased in rubber. 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
inductivity values (see the attached
certificate of conformity) and the
requirements for electromagnetic
compatibility.
! Economy Series equipment may
only be operated in an ambient
temperature 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.
! Connect only Sartorius-approved
cables to the data interface port
on the Economy scale. Attach the
cable securely to the interface port.
To ensure safety, disconnect the
equipment from power before
connecting or disconnecting the
data cable. The Zener barrier for
data transmitted to peripheral
equipment located outside the
hazardous area/location must be
certified; for instance, the type
Z966 (EEx ia) IIC Zener barriers
made by the Pepperl + Fuchs
company can be used. The barriers
must be installed outside the
hazardous area/location and must
be connected to the equipotential
bonding conductor by an
equipotential busbar. The barrier
can be used in an ambient
temperature from 0°C to +40°C
(+32°F to +104°F). Connected
devices must not be capable of
supplying more than 250 V to the
barriers.
