ELECTRICAL CONNECTIONS

All of the operations must be carried out by qualified staff, 
in accordance with regulations in force. For any electrical-
related procedure, refer to the electrical diagrams supplied 
with the unit. We also suggest making sure that the 
characteristics of the electrical network are suitable for the 
absorption levels repor ted in the electrical data table.

Before carrying out any operation on 
electrical parts, make sure the power supply 
is disconnected. Check that the mains voltage 
is compatible with the specifications of the 
unit (voltage, number of phases, frequency) 
shown on the unit rating plate. The 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 
and with the regulations in force.

MAINTENANCE

Maintenance operations must be carried out 
exclusively by a manufacturer-authorised 
assistance centre or by qualified staff. For 
safety reasons, before carrying out any 
maintenance or cleaning, turn the equipment
