 The wire size in the above table shows the designed values based on HIV cables (with thermal
resistance of 75°C).
 If the wiring length exceeds 20 m, a thick power line needs to be used.
 When connecting wires to the main circuit terminal block, use round crimping terminals (UL-
certified item) suitable for the wires for use. Use a crimp tool recommended by the
manufacturer of the crimping terminal to crimp the terminal.
 Use a ground wire with a diameter equal to or thicker than that indicated on the power line.
 It is recommended to tight screws at the "maximum value" of the tightening torque in the above
table.
