1) Use a dedicated power supply for each unit. Ensure that each unit is wired individually.
2) When installing wiring, consider ambient conditions (e.g., temperature, sunlight, rain).
3) The wire size is the minimum value for metal conduit wiring. If voltage drop is a problem, use a wire that is one size thicker.
Make sure the power-supply voltage does not drop more than 10%.
4) Specific wiring requirements should adhere to the wiring regulations of the region.
5) Power supply cords of appliances for outdoor use shall not be lighter than polychloroprene sheathed flexible cord (design 60245 IEC57).
6) A switch with at least 3 mm (1/8 in.) contact separation in each pole shall be provided by the hot water heat pump installer.
7) Do not install a phase advancing capacitor on the motor. Doing so may damage the capacitor and result in fire.
8) Depending on the installation conditions (power-supply imbalance, etc.), the amount of current may increase. Select a breaker with proper
capacity to suit the local usage conditions.

Be sure to use specified wires and ensure no external force is imparted to terminal connections.
Loose connections may cause overheating and fire.

Be sure to use the appropriate type of overcurrent protection switch. Note that overcurrent may include direct current.

Some installation sites may require an installation of an earth leakage breaker for the inverter. If no earth leakage breaker is installed,
there is a danger of electric shock.

Only use properly rated breakers and fuses. Using a fuse or wire of the wrong capacity may cause malfunction or fire.
