1.8 Safety Precautions

Please read the entire manual before unpacking, setting up, or
operating this instrument. 

Pay particular attention to all warning and caution statements.
Failure to do so could result in serious injury to the operator or
damage to the equipment. 

To ensure the protection provided by this equipment is not
impaired, do not use or install this equipment in any manner
other than that which is specified in this manual.

1.9 Safety Conventions

Electrical equipment marked with this symbol
may not be disposed of in European public
disposal systems after 12 August 2005. In
conformity with European local and national
regulations (EU Directive 2002/96/EC), European
electrical equipment users must now return old
or end-of-life equipment to the manufacturer for
disposal at no charge to the user. 

Note.

For return for recycling, please contact the 

equipment manufacturer or supplier for instructions on how 
to return end-of-life equipment for proper disposal.

Note.

The following only applies to European customers.

ABB is committed to ensuring that the risk of
any environmental damage or pollution caused
by any of its products is minimized as far as
possible. The European Waste Electrical and
Electronic Equipment (WEEE) Directive
(2002/96/EC) that came into force on August
13 2005 aims to reduce the waste arising from
electrical and electronic equipment; and
improve the environmental performance of all
those involved in the life cycle of electrical and
electronic equipment.

In conformity with European local and national
regulations (EU Directive 2002/96/EC stated
above), electrical equipment marked with the
above symbol may not be disposed of in
European public disposal systems after 12
August 2005. 

The European Union RoHS Directive and
subsequent regulations introduced in member
states and other countries limits the use of six
hazardous substances used in the
manufacturing of electrical and electronic
equipment. Currently, monitoring and control
instruments do not fall within the scope of the
RoHS Directive, however ABB has taken the
decision to adopt the recommendations in the
Directive as the target for all future product
design and component purchasing. . 

RoHS

Warning.

To familiarize yourself with handling precautions,

dangers and emergency procedures, always review the
Material Safety Data Sheets prior to handling containers,
reservoirs, and delivery systems that contain chemical
reagents and standards. Protective eye wear and protective
hand wear. is always recommended when contact with
chemicals is possible.

Warning.

In this manual, a warning is used to indicate a

condition which, if not met, could cause serious personal
injury and/or death. Do not move beyond a warning until all
conditions have been met. 

If a warning sign appears on the instrument itself, refer to
Precautionary Labels – UL Certification and Electrical Safety
– CEI/IEC 61010-1:2001-2 for an explanation.

Caution.

A caution is used to indicate a condition which, if

not met, could cause minor or moderate personal injury
and/or damage to the equipment. Do not move beyond a
caution until all conditions have been met. 

Note.

A note is used to indicate important information or

instructions that should be considered before operating the
equipment.
