Motor-compressor may not be connected to other voltage and frequency than assigned on the motor-
compressor label.
In case of fuse or circuit breaker reaction. never replace or reset before checking ground fault (short circuit to
ground). Blown fuse or tripped circuit breaker could be indicator of ground fault situation.
In single-phase installations with internal overload protector, the Phase wire must be protected by a circuit
breaker and connected directly to common pin. The neutral wire must be connected to the relay starting device.
The system must be grounded.
WARNING
1.1 • ELECTRICAL INSTALLATION
In order to assure appropriate motor-compressor operation, it must be installed in electrical installation system
(grid) with sufficient current capacity with respect to motor-compressor rated load amperage and locked rotor
current. Otherwise, possible problems may occur due to current breaker or fuse intervention or due to starting
ability issues caused by voltage drop over the line.
Appliance installation must be established by trained personnel only.
Before operation, motor-compressor must be grounded (appropriate earth connection must be established).
Always follow connection diagram scheme in order to assure motor-compressor safety and correct operation.
Only approved electrical accessories have to be used, corresponding to specific model of motor-compressor.
Not specified relay starting device may cause the capacitor to overheat. Overheated
capacitors are subject to rupture which can lead to leakage of overheated material that
can lead to burns.
The use of relay starting device other than specified can generate short circuit in the
hermetic compressor terminal, causing the expulsion of hermetic pins causing refrigerant
and oil leakage.
