sure that this operation won’t make you exceed the voltage and current

permitted for the appliance in use.

The appliance for the test must have correct nominal values.

16. Periodically check that the cables are not subject to wear, corrosion,

excessive pressure, vibrations, sharp edges or any other hostile

environmental situation.

17. When intervening inside the refrigerating circuit to carry out repairs or for

any other reason, the conventional procedures must be followed:

maintenance and that the possible associated electric components are

sealed, to prevent switching on in case of leak of refrigerant.
