PRECAUTIONS :
-
For the supply version in 115V or 230VAC, the DBX2000 leaves our workshops with the jumper
positioned for use in 230VAC (unless stated when ordering).
Check the position of the jumper according to the mains voltage:
-
If a change of fuse is necessary, replace it with a fuse of the same calibre (see page 9 characteristics).
-
Fix the DBX2000 in a vertical position
-
Avoid dusty air entering the pressure inlets.
-
Take the necessary precautions to satisfy the device characteristics (humidity, maxi pressure, etc.).
-
Do not remove the front face of the DBX2000 to connect (only the cover of the connections)
-
For the connection of the signals 4-20mA, it is recommended that you use a shielded cable and do not
follow the routing of the power cables.
-
The work must always be carried out by duly qualified personnel.
WARNING: if you change the supply voltage, you must update the data plate
located on the outside of the box.
