Series 321
1. Introduction
There are various models in the 321 Series. These brief instructions describe the balance with windshield. If you
are using a less complex model, the descriptions of elements that are not included can be skipped.
These brief instructions are intended as an initial overview and are an extract from the original operating instruc-
tions. The brief instructions must be available at all times at the workstation. More detailed descriptions can be
found in the original operating instructions, which can be downloaded from our website.
You should read the original operating instructions in full to ensure that you make the best possible use of your
balance.
2. Safety precautions
– When the balance is used in environments with increased safety requirements, the relevant precautions must be taken.
– The balance must only be operated with a fault-free power supply unit.
– Before connecting the power supply unit, ensure that the operating voltage specified on the power supply unit matches the
mains supply.
– The balance must only be operated with the power supply unit supplied.
– If safe operation of the balance is not possible, it must be disconnected from the power supply and secured against unin-
tentional use.

1. Einleitung
Es gibt verschiedene Modelle der Serie 321. In dieser Kurzanleitung wird die Waage mit Windschutz beschrie-
ben. Wenn Sie ein weniger komplexes Modell vorliegen haben, sind die Beschreibungen zu nicht vorhandenen
Elementen auszulassen.
Diese Kurzanleitung dient als erste Übersicht und ist ein Auszug aus der original Betriebsanleitung. Die Kurzanlei-
tung muss am Arbeitsplatz jederzeit verfügbar sein. Detaillierte Beschreibungen finden Sie in der original Betriebs-
anleitung, die von unserer Homepage heruntergeladen werden kann.
Sie sollten die original Betriebsanleitung vollständig durchlesen, damit Sie die Waage optimal nutzen können.
2. Sicherheitshinweise
– Bei Verwendung der Waage in Umgebungen mit erhöhten Sicherheitsanforderungen sind die entsprechenden Bestimmun-
gen zu beachten.
– Die Waage darf nur mit einem einwandfreien Steckernetzteil betrieben werden.
– Vor dem Einstecken des Steckernetzteils ist sicherzustellen, dass die auf dem Steckernetzteil angegebene Betriebsspan-
nung mit der Netzspannung übereinstimmt.
– Die Waage darf nur mit dem mitgelieferten Steckernetzteil betrieben werden.
– Wenn ein gefahrloser Betrieb der Waage nicht möglich ist, so ist die Waage vom Stromnetz zu trennen und gegen unbeab-
sichtigten Betrieb zu sichern.
