Tab. 1 - Electrical data with premium fan module
* ATTENTION Only universal (type B, B+) RCD protective devices are permitted.
NOTES:
• The cables have to be sized in compliance with local standards and according to the type and characteristics (e.g. Amperes) of installation.
• The data in the tables do not consider the absorbed current from the condensate pump and for other options not explicitly described.
• The specific energy allowed to flow from the circuit breakers, installed by the user, must be lower than 300.000A
2
x s.
• Prescriptions on the differential relay required to the user:
• for special places (healthcare facilities, etc...) comply with the local regulations;
• For ordinary places, a low sensitivity is suggested (300 mA) coordinated with the value of the ground heater (IEC 364): Ra 50/Ia (Art. 413.1.4.1, CEI 648 or IEC60364445);
• In case of frequent over-voltages with mains impulse, it is advisable to install a selective differential and to evaluate the need for adopting other devices;
• The FLA is for units without the options of condensate pump and condensing unit;
• The FLA is for units with AUTOMATIC FUNCTIONS only: in manual mode operation the FLA must be lower than the max. current of the main switch.
