Warning and Safety Information
Intended Use
Combics explosion-protected instru-
ments equipped with Option Y2 meet
the requirements for Category 3
equipment in accordance with Council
Directive 94/9/EC and are rated for
use in Zone 2 and 22 hazardous areas.
Please refer to the Annex to the
Statement of Conformity for the
equipment designation.
The permissible temperature range
during operation is –20°C to +40°C
(–4°F to +104°F).
The additional equipment required
was installed by Sartorius during the
production process.
The weighing instrument meets the EC
Directives and standards governing:
– electrical apparatus
– explosion protection
– electromagnetic compatibility
– electrical safety
Improper use or handling, however, can
result in damage and/or injury.
– Do not expose the equipment to aggressive
chemical vapors or to extreme tempera-
tures, moisture, shocks, or vibration.
The equipment is rated for use in Zone 2
and 22 hazardous areas. Please make sure
the currently valid regulations and guide-
lines for installing equipment in the areas
listed above are strictly observed.
– When using the equipment in hazard-
ous areas, make sure there is no current
or voltage in the equipment before con-
necting or disconnecting current-carrying
cables to or from the device. Disconnect
the scale from AC power before connecting
or disconnecting cables.
– Refer to the enclosed “Installation
Instructions“ before installing the equip-
ment: Drawing 65954-751-16-A4
– Installation in a Zone 2 or 22 hazardous
area must be performed by a trained
technician. The power connection must be
made in accordance with the regulations
applicable in your country.
If you need assistance, contact your
Sartorius dealer or the Sartorius Service
Center. 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.
– Make sure all metal parts are grounded to
prevent buildup of static electricity.
– Have the equipment inspected at appropri-
ate intervals for correct functioning and
safety by a trained technician.
– If you see any indication that the equip-
ment cannot be operated safely (for
example, due to damage), disconnect the
device from power and lock the equipment
in a secure place so that it cannot be used
for the time being. Make sure the appli-
cable accident prevention regulations are
observed by all operating personnel.
– Always make sure the equipment is discon-
nected from AC power before performing
any installation, cleaning, maintenance or
repair work.
– Handle the equipment with care in accord-
ance with its IP protection rating. Make
sure the IP protection is not damaged
when cleaning the equipment.
– 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.
Conditions for Installation:
Before putting the equipment into opera-
tion, it is important to make sure that the
power cord is correctly connected to the
power outlet (mains supply). All equip-
ment must be connected to the equipoten-
tial bonding conductor by connecting the
grounding cable (not included in delivery)
to the grounding terminals or bore holes
provided for this purpose on each device.
The dimensions of the grounding cable
are specified in national regulations for
electrical installations. Installation must
be performed by a trained technician in
accordance with national regulations and
acknowledged technological standards.
Use only cabling and extensions approved
by Sartorius, as these are made in accord-
ance with the restrictions on permissible
cable lengths imposed by both the
capacitance and inductivity values and
the requirements for electromagnetic
compatibility.
Before putting the weighing system into
operation for the first time, make sure
there is no hazard of explosion present
at the place of installation. If there is any
indication that the equipment does not
function properly (e.g., display remains
blank) due to damage during transport,
disconnect the equipment from power
and notify your nearest Sartorius Service
Center.
Before connecting or disconnecting data
cables or control lines to or from the
device, make sure all equipment is discon-
nected from power. If the equipment
housing is opened by anyone other than
persons authorized by Sartorius, this will
negate its conformity with regulations
governing use in the stated Zone 2 and
22 hazardous areas and result in forfeiture
of all claims under the manufacturer‘s
warranty.
If you use the equipment in a hazardous
area outside Germany, you must comply
with the national electrical code and appli-
cable safety regulations of your
country. Ask your local Sartorius office
or dealer for information on the legal
regulations applicable in your country.
