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.
✔Use of the terminal in places with potentially explosive atmospheres
or in areas where there is a risk of fire is strictly prohibited.
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 Prescriptions of use
✔Strictly comply with the instructions in this manual during use.
✔In the event of any discrepancy between the information in this
manual and the instrument purchased, contact your Dealer or the
Manufacturer's After-Sales Service for clarification.
✔Always observe the indications given on the warning and danger
plates on the terminal.
✔Check that all the safety guards are in place and that the connection
cables are in good condition and connected correctly.
✔Check that the terminal is connected to an electrical outlet socket
equipped with an effective earth connection. Make sure that the line
complies with the applicable regulations. Check that there is no
difference in potential between the earth and neutral conductors.
✔If the terminal is to be connected to other devices (e.g. a computer),
these devices must be disconnected from the electrical supply before
connection to the terminal.
D400
1-15

✔All maintenance and/or repairs must be carried out by authorised

3.1 Connection of the terminal to the electrical supply line
DANGER
Check that:
✔The voltage and frequency of the electrical supply line
corresponds to the indications on the warning plate on the
rear of the terminal (see point 4 Figure 3.1 on page 1-17 );
✔the mains outlet socket to which the terminal is connected
is equipped with an earth;
✔the warning and danger signs are present and legible;
✔failing this, notify your maintenance personnel or contact
our Assistance Service directly;
For the correct connection of the terminal to the electrical supply line,
proceed as follows:
✔plug the 3-pin connector of the power lead into the connector on the
rear if the terminal;
✔insert the plug of the power lead into the correct mains outlet socket.
The terminal complies with the European Directive for electromagnetic
compatibility, however it is good practice to provide a separate power
supply line for the terminal.
D400
1-18

WARNING
Do not route the terminal connection cables alongside power
cables as these could cause disturbances that interfere with
the correct operation of the terminal. Only use the connection
cable supplied with the terminal. If the cable supplied is too
short, do not attach an extension lead but contact the
Manufacturer.
3.2 Connection of the terminal to the platform scale
The terminal is normally supplied with a pre-wired cable for connection
to the platform scale. The female connector on this cable should be
plugged into the male 9/15-pin connector (JBIL) on the rear of the
terminal (see point 1 Figure 3.1 on page 1-17 ). The connection method
may vary according to the type of transducer on the platform scale
(analogue or digital).
WARNING
The cable screen should always be connected to the metal
cap of the 9/15-pin connector. Do not route the scale
connection cable alongside power cables.
D400
1-19

3.2.1 Equipotentiality between the terminal and the platform
scale
Check that a condition of equipotentiality exists between the metal parts
of the terminal and the platform scale.
If in doubt, connect the terminal and the scale using a earth wire of at
least 6mm² using the earth screw on the rear of the terminal (see point 7
Figure 3.1 on page 1-17 ).
The cables required for this connection are to be provided by the
customer.
3.2.2 Connection of analogue load cells
The diagram below shows the pinout for the JBIL connector for
connection to scales with analogue load cells.
