WARNING
■ A main switch or other means of disconnection, having a contact separation in all poles, must be incorporated in
the fixed wiring in accordance with relevant local laws and regulations.
■ Switch off the power supply before making any connections.
■ Never squeeze bundled cables and make sure they do not come in contact with the piping and sharp edges. Make
sure no external pressure is applied to the terminal connections.
■ All field wiring and components must be installed by a licensed electrician and must comply with relevant local
laws and regulations.
■ The field wiring must be carried out in accordance with the wiring diagram supplied with the unit and the instructions given below.
■ Be sure to use a dedicated power supply. Never use a power supply shared by another appliance.
■ Be sure to establish a ground. Do not ground the unit to a utility pipe, surge protector, or telephone ground.
Incomplete grounding may cause electrical shock.
■ Be sure to install a ground fault circuit interrupter. Failure to do so may cause electrical shock.
■ Be sure to install the required fuses or circuit breakers.
☞
NOTE
■ Be sure to install a differential switch with the following characteristics:
- intervention value equal to 30 mA
- trip time less than 0.1 s
- that it is compatible with the inverter (resistant to high frequency electromagnetic
disturbances) in order to avoid unnecessary interventions
1. Remove the side panel (1).
2. Make the connections referring to the wiring diagrams of the unit.
3. Close the machine up again.
☞
NOTE. The unit is equipped with an inverter. Installing a power factor correction not only reduces the effect of power factor improvement, but can also
cause an abnormal heating of the condenser due to high frequency waves. Never install a power factor device as it may cause damage to the unit.
