ELECTRICAL CONNECTIONS

General electrical characteristics
• The customer must provide a separate power line for the conditioner fitted with an automatic safety device (heavy-
duty circuit breaker) upline from the line.
• Make sure that the power line voltage matches that indicated on the rating plate.
• The power line of all the models must be fitted with a suitably sized earth connector.
• The lines powering the fixed loads of the unit (compressor, fans, etc.) have been sized according to current legisla-
tion governing overload and short circuit protection.
• The conductors from the power supply running directly to the input terminals of the general switch must be connec-
ted (consult the wiring diagrams supplied with the unit).
• The electrical panels are fitted with a marked terminal for connecting the earth wire.
Electrical connections
To allow the conditioner to start, make the electrical connections as shown in the wiring diagrams supplied with the unit.
The two units must be connected to an efficient earth circuit. The maker declines all liability if this precaution is ignored.
N.B.: When working on the electrical system, refer to the wiring diagrams supplied with the unit. For connec-
tions to the power and control circuits, comply with the specifications shown in the following tables.
