The packaging has been designed to ensure that the balance will not be damaged

After unpacking the balance, please check it immediately for any visible damage
as a result of rough h and 1during shipment.
lf this is the case, proceed as directed in the section entitled "Safety inspection."
Save all parts of the packaging and the box for your balance to avoid damage
during transportation. You may ship your balance only in the complete original
Standard packaging supplied. Before you pack your balance, unplug all con-
nected cables to prevent damage.
Do not expose the balance unnecessarily to extreme temperatures, moisture,
shocks, blows or vi brat Ions.
Transporting the Balance
To transport the balance, lift it by the housing base using both hands.
Do not lift it by the display unit or by the draft shield!

Installation Instructions
Ambient Conditions
Unfavourable ambient conditions may affect the weight readouts.
Therefore, choose a suitable place to set u p your balance. lt should not be ex-
posed to the following:
— Extreme heat radiation
— Drafts
— Extreme- vibrations
— Aggressive chemical atmospheres
Set up your balance on a sturdy fable or on a wall console (see "Accessories" in
"Part l): Product Data Sheet").
Do not expose the balance to extreme moisture over long periods. Moisture in the
air can condense on the surfaces of a cold balance whenever it is brought to a
substantially warmer place. lf you transfer the balance to a warmer area, make
sure to condition it for about 2 hours at room temperature, leaving it unplugged.
Afterwards, if you keep the balance connected to AC power, the continuous posi-
tive difference in temperature between the inside of the balance and the outside
will practically rule out the effects of moisture condensation.
You can adapt the balance to your specific requirements and to the ambient con-
ditions simply by changing the code settings in the balance operating menu. For
more information, turn to "Part III: Balance Operating Menu."

Getting Started
Place the components listed below inside the weighing chamber one at a time in
the Order given:
- shield disk (8)
- weighing pan (7)
- protective ring (6)
- interior weighing chamber draft shield (depending on the balance model) (5)
Place the small draft shield cover (2) on top of the semi cylindrical interior draft
shield door (4).
Adjusting the Exterior Draft Shield Element
The draft shield consists of two semi cylindrical dements, one of which functions as
a door. Turn the exterior draft shield element (3) by the riffled part on the bottom
to the position you desire, That way, you will have the opening located exactly
where it is most convenient for you. When adjusting the exterior element, be sure
to shield the weighing chamber from you r breath and the warmth of your hands
(see diagram on the left in addition).
Depending on your application, you can define the menu code so that the inferior
draft shield door (4) is opened by motor or by hand (see pp. 14).
Adjusting the Swivel-Mounted Display Unit
Move the swivel-mounted display unit (11) around the base of the draft shield to
adjust it to the position you desire (+/- 85°).

Connecting the Balance to Line Voltage
The balance is energized by a power supply. Make sure that the voltage rating
printed o n this unit is identical to your local line voltage.
lf the voltage specified on the label or the plug design of the power supply does
not match the rating or Standard you use, please contact your Sartorius Office or
dealer.
The power supply is suitable for installation as stationary equipment. To use a
main feeder cable from the ceiling or to mount a CEE plug, you will have to make
arrangements inside your facilities for installation of such cable equipment by a
certified electrician.
Important Note
Use only original Sartorius Power Supplies identified by the Sartorius label. Use of
power supplies from other manufacturers, even if these units have an approval
identification marking from a national testing laboratory, requires the consent of
an authorized Sartorius service technician.
To operate your balance using an external rechargeable battery, pack, see "Ac-
cessories" in "Part II: Product Data Sheet.".
Detailed information on additional options for powering the balance is available
in our Service Information bulletin, no. 15/88 (fore example, using local! extra-
low voltage).
Plug the cord of the power supply into the AC jack on the balance, Then insert the
plug of the power supply in a wall outlet.
