contents of this manual.
“Qualified personnel” means persons that have received sufficient training and have acquired
enough professional experience to be authorised by the "Person in charge of safety" to perform
installation, use and maintenance work.
Contact your nearest Service Centre if problems occur.
Any attempt on the part of unauthorised personnel to dismantle or modify the terminal is
prohibited; in this event, the warranty will be immediately invalidated and the Manufacturer may
not be held liable for any damage to people or property.
The alteration or removal of the data plates and seals is strictly prohibited; as a consequence,
make sure that all plates and labels are readable and, on the contrary, contact the After Sales
Office.
The manufacturer shall not be liable for any damages caused by incorrect handling of the
terminal.
The information and illustrations contained in this manual were up to date at the time of
publication.
The Manufacturer is committed to constantly improving its products, therefore some components

2 SAFETY INSTRUCTIONS
2.1 Prohibited uses
The instrument you have purchased is a weighing system and has been designed and manufactured
as such.
The instrument is primarily intended for the weighing of goods.
It is forbidden to use the terminal without taking the necessary precautions for safe use.
Any other use shall only be permitted if expressly authorised by the Manufacturer.
2.2 Regulations
The operating conditions for the electronic terminal are subject to the regulations in force in the
country in which the terminal is used.
All use of the terminal in conditions which do not comply with these regulations is prohibited.
2.3 Recommendations for installation
2.3.1 Classification of zones and substances
The terminal-power supplier, load cells, connection cable system must be approved for installation in
the zone of use.
The user customer must therefore analyse and classify the hazardous zones and dangerous
substances present.
CAUTION
The Manufacturer does not classify zones and substances.

19
DS440IS
2.3.2 Compatibility
Once the zones and substances have been classified, the equipment can be chosen with protection
systems suitable for these zones/substances.
2.3.3 Surface or underground
The weighing instruments described in this manual are suitable for use on the surface (group II).
2.3.4 Categories of equipment
The appliances are classified in categories, depending on their safety (1, 2, 3).
There is also a breakdown in equipment for the presence of dust (D = Dust) and gas (G = Gas).

2.3.5 Groups of substances and surface temperatures
The gases present are classified according to the energy and firing temperature (IIC, IIB, IIA and T6....T1).
2.3.6 IP protection degree and surface temperature
The casings of appliances installed where dust is present must also possess a certain IP protection degree
with a declared maximum surface temperature. This latter must be compatible with the dust ignition
temperature.
2.3.7 Description of the system installed
To facilitate the installation operations and make it easier to check whether the electrical and mechanical
parameters of the various parts forming the system are compatible with the surrounding conditions
(presence of gas and dust), the Manufacturer provides certain typical systems as described below. The
components of these systems are described and their compatibility is guaranteed.
DANGER
The customer must check to make sure that these systems are compatible with the zones and
substances in his application.
