Safety tips, electrical protection class
!This instrument was built and tested in accordance
with the safety regulations for measuring and control
instrumentation for protection class I (protective earth
connection) according to IEC 1010/ EN61010-1 or
VDE 0411. The instrument was delivered in safe con-
dition. To maintain this condition and to ensure safe
operation, the operator must follow the instructions
and warnings given in this documentation
Protective earth
!The connecting cable of the unit complies with the
regulations in accordance with VDE 0411 or
EN61010. The mains plug must contain a protective
earth conductor, which must not be interrupted inside
or outside this instrument (e.g. by using an extension
cable without protective earth). Before commission-
ing, acceptance of the installation by a technically
competent expert is required.
Measurement category
!This instrument is designed for measurement category
I, with a maximum of 8.5V. To ensure safe operation
do not use this instrument for measurements within
the measurement categories II, III or IV.
!Opening the instrument
CAUTION: DANGER TO LIFE!
– Working on the instrument when it is switched on can
be dangerous to life. Disconnect the instrument from
the supply voltage! When removing covers of parts
by means of tools, live parts or terminals may be
exposed. Capacitors in the unit may still be charged
even after disconnecting the unit from all voltage
sources.
– As the unit has no power switch, to completely remove
AC power from the unit, disconnect the AC power cable
from the mains socket.
– Do not expose the scale unnecessarily to aggressive
chemical vapors or to extreme temperatures,
moisture, shocks, or vibration.
– Avoid exposing the scale to static electricity; be sure
to connect the equipotential bonding conductor to the
junction box.
Repair and maintenance
– Repairs are subject to checking and can be carried out
only at Acculab. In case of defect or functional trouble,
please contact your local Acculab organization for
repair. When returning the instrument for repair, an
exact and complete fault description must be supplied.
Only a trained technician aware of the hazards
involved may carry out maintenance work, during
which the relevant precautions must be taken.
Important note:
– Make sure that the construction of the instrument is
not altered to the detriment of safety. In particular,
leakage paths, air gaps (of live parts) and insulating
layers must not be reduced. The manufacturer cannot
be held responsible for personal injury or damage
caused by an instrument repaired incorrectly by user
or installer.
Safety Precautions

4
– Only authorized service technicians who have been
trained by Acculab and who follow Acculab’s standard
operating procedures for maintenance and repair may
open the scale. If you see any indication that the scale
cannot be operated safely (for example, because of
equipment damage), turn off the scale and lock it in a
secure place so that it cannot be used for the time
being.
– Suspension points are provided on platforms of
1,000 x 1,000 mm or larger. If you need to transport
or lift the scale or load plate using a crane, do not step
underneath the suspended scale or load plate.
Be sure to observe the corresponding safety rules
and regulations for prevention of accidents.
Do not damage the scale or the load receptor during
transportation.
– If you use suction lifting equipment to lift the load
plate, always wear gloves, hard-toed safety boots and
protective clothing. Warning: This procedure can cause
personal injury! Only reliable personnel who are quali-
fied to perform such work are allowed to use suction
lifting equipment.
– Always make sure the scale is disconnected from AC
power before performing any installation,
cleaning, maintenance or repair work.
– Check the pin assignment if you use cables purchased
from a different manufacturer. Before connecting such
a cable to Acculab equipment, check the pin assign-
ment on the corresponding wiring diagram or chart
and disconnect any wires that are assigned differently
from those specified by Acculab. The operator shall be
solely responsible for any damage or injuries that may
occur when using cables not supplied by Acculab.
!Note:
– Do not use this equipment in hazardous areas.
– Make sure the voltage rating printed on the power
supply is identical to your local line voltage.
– Use only commercially available batteries
(rechargeable or dry-cell battery). If you use
a rechargeable battery, use only 12V 2.3AH.
– The scale is energized at all times unless you discon-
nect the AC power and the battery.
– Exposure to excessive electromagnetic interference
can cause the readout value to change. Once the dis-
turbance has ceased, the instrument can be used
again in accordance with its intended purpose.

Storage and Shipping Conditions
Do not expose the scale to shocks, vibrations, moisture or
extreme temperatures.
Unpacking the Scale
After unpacking the scale, check it immediately for any
visible damage as a result of rough handling during
shipment.
Note:
– The display and control unit is attached to the weighing
platform via a cable.
– If you see any sign of damage, proceed as directed in the
chapter entitled “Care and Maintenance,” under the
section on “Safety Inspection.”
– Save the box and all parts of the packaging until you
have successfully installed your scale. Only the original
packaging provides the best protection for shipment.
Before packing your scale, unplug all connected cables to
prevent damage.
Equipment Supplied
The equipment supplied includes the components listed
below:
– Scale with attached display and control unit
– Load pan
– Installation and operating instructions
Installation Instructions
The Acculab Exceleron scales are designed to provide
reliable weighing results under normal ambient conditions.
When choosing a location to set up your scale, observe the
following so that you will be able to work with added
speed and accuracy:
– Set up the scale on a stable, even surface
– Avoid placing the scale in close proximity to a heater or
otherwise exposing the scale to heat or direct sunlight
– Protect the scale from drafts that come from open windows
or doors
– Avoid exposing the scale to extreme vibrations during
weighing
– Protect the scale from aggressive chemical vapors
– Do not expose the scale to extreme moisture over long
periods
Conditioning the Scale
Moisture in the air can condense on the surfaces of a cold
scale whenever it is brought into a substantially warmer
place. If you transfer the scale to a warmer area, make
sure to condition it for about 2 hours at room temperature,
leaving it unplugged from AC power. Afterwards, keep the
scale continuously connected to AC power.
