When using an AC200V to 240V power supply.
•
In case of using a 200V~240V power supply, diverge the main power supply cables by using a pull box as shown in the figure.
•
The electricity supply to the unit should be via an exclusive power control switch and protective circuit breaker, certified and installed
in accordance with local or national safety regulations.
•
Use an earth leakage breaker with medium sensitivity, and an activation speed of 0.1 or less. If this is not fitted, there is a risk of electric
shock and/or fire.
•
Install an earth leakage breaker, fuse and circuit breaker for each outdoor unit power line. Not fitting it may cause an electric shock
or fire.
