USER WARNINGS 

 

RECOMMENDATIONS FOR THE PROPER USE OF WEIGHING INSTRUMENT 

-

 

Keep away from heat sources and direct sunlight 

-

 

Repair the instrument from rain (except special IP versions) 

-

 

Do not wash with water jets (except special IP versions) 

-

 

Do not dip in water 

-

 

Do not spill liquid on the instrument 

-

 

Do not use solvents to clean the instrument 

-

 

Do not install in areas subject to explosion hazard (except special Atex versions) 

 
 

RECOMMENDATIONS FOR CORRECT INSTALLATION OF WEIGHING INSTRUMENTS 

 

The terminals indicated on the instrument’s wiring diagram to be connected to earth must 

have the same potential as the weighed structure (same earthing pit or earthing system). If 

you are unable to ensure this condition, connect with an earthing wire the terminals of the 

instrument (including the terminal – SUPPLY) to the weighed structure. 

The cell cable must be individually led to its panel input and not share a conduit with other cables; 
connect it directly to the instrument terminal strip without breaking its route with support terminal strips. 
Use “RC” filters on the instrument-driven solenoid valve and remote control switch coils. 

Avoid inverters in the instrument panel; if inevitable, use special filters for the inverters and separate 
them with sheet metal partitions. 
The panel installer must provide electric protections for the instruments (fuses, door lock switch etc.). 
It is advisable to leave the equipment always switched on to prevent the formation of condensation.
