drop more than 10%.

Wiring of main power supply and equipment capacity
• 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.
•
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.
