MAINTENANCE

MAINTENANCE MAINTENANCE MAINTENANCE MAINTENANCE
1 ) REMOVE POWER FROM THE POWER SUPPLY
TERMINALS AND FROM RELAY OUTPUT
TERMINALS
2 ) Remove the instrument from case.
3 ) Using a vacuum cleaner or a compressed air jet (max.
3 kg/cm ) remove all deposit of dust and dirt which may
2
be present on the louvers and on the internal circuits
trying to be careful for not damage the electronic
components.
4) To clean external plastic or rubber parts use only a
cloth moistened with:
- Ethyl Alcohol (pure or denatured) [C
- Isopropil Alcohol (pure or denatured) [(CH
or
- Water (H O)

5 ) Verify that there are no loose terminals.
6 ) Before re-inserting the instrument in its case, be sure
that it is perfectly dry.
7 ) re-insert the instrument and turn it ON.
