15. ELECTRICAL CONNECTIONS
WARNING
Before carrying out any work on the equipment, make
sure that the electrical power supply is disconnected
and that there is no possibility of the unit being
started inadvertently.
Non-compliance with the above instructions can lead
to injury or death by electrocution.
The electrical installation must be performed by a fully qualied electrician, and in accordance with local
electrical standards and the wiring diagram corresponding to the unit model.
Any modication performed without our prior authorisation may result in the unit’s warranty being declared
null and void.
The power supply cable section must be sufcient to provide the appropriate voltage to the unit’s power
supply terminals, both at start-up and under full load operating conditions.
The power supply cable shall be selected in accordance with the following criteria:
1. Power supply cable length.
2. Maximum unit starting current draw – the cables shall supply the appropriate voltage to the unit
terminals for starting.
3. Power supply cables’ installation mode.
4. Cables’ capacity to transport the total system current draw.
Short circuit protection shall be provided. This protection shall comprise fuses or circuit breakers with high
breaking capacity, mounted on the distribution board.
If the local control includes an remote ambient temperature sensor and/or a set temperature adjustment
module, these shall be connected with shielded cable and shall not pass through the same conduits as the
power supply cables as the voltages induced may create reliability faults in the unit’s operation.
