Wiring of main power supply and equipment capacity

1. Use a separate unit power and heater power.
2. Bear in mind ambient conditions (ambient temperature,direct sunlight, rain water,etc.) when
proceeding with the wiring and connections.
3. The wire size is the minimum value for metal conduit wiring. The power cord size should be 1 rank
thicker taking into account the line voltage drops. 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 parts of appliances for unit use should not be lighter than polychloroprene
sheathed flexible cord.

WARNING
• Follow ordinance of your governmental organization for technical standard related to
electrical equipment, wiring regulations and guidance of each electric power company.
• Make sure to use specified wires for connections so that no external force is imparted to
terminal connections. If connections are not fixed firmly, it may cause heating or fire.
• Make sure to use the appropriate type of overcurrent protection switch. Note that generated
overcurrent may include some amount of direct current.
CAUTION
• Some installation site may require attachment of an earth leakage breaker. If no earth leakage
breaker is installed, it may cause an electric shock.
• Do not use anything other than breaker and fuse with correct capacity. Using fuse and wire or
copper wire with too large capacity may cause a malfunction of unit or fire.
