INSTALLATION
■ The unit is equipped with an inverter. Installing a power factor correction not only reduces the effect of power factor im-
provement, 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.
☞
■ A main switch or other means of disconnection, having a contact separation in all poles, must be incorporated in the fi xed 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 exter-
nal pressure is applied to the terminal connections.
■ All fi eld wiring and components must be installed by a licensed electrician and must comply with relevant local laws and regulations.
■ The fi eld 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 (30 mA). Failure to do so may cause electrical shock.
■ Be sure to install the required fuses or circuit breakers.
WARNING
■ 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
