7 ELECTRIC AND CONTROLLER INSTALLATION
 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.
7.1 Precautions
The power cable and communication cable can be identified in the following ways:
Method 1: Use sheaths in different colours.
Method 2: Use different types of cables.
The diameter of the power cable is larger than that of the communication cable. Alternatively, adopt
three cores or more for the power cable and two cores for the communication cable.
 Both the power cable and communication cable must be connected properly. If the power
cable is connected to the communication port, the main board will be burnt.
