characteristics of the electrical network are suitable for the
absorption levels reported in the electrical data table.
Before carrying out any operation on
electrical parts, make sure the power supply

voltage must not fluctuate by more than ±5%
in relation to the rated value. The electrical
connections must be set up according to the
electrical diagram attached to the specific unit
