4. WIRING
● Wiring must be performed by an authorized person qualified in electrical work.
● Do not test the insulation of cable that connects the inverter with high-voltage
insulation testing devices.
● Can not install the inverter until discharged completely after the power supply is
switched off for 10 minutes.
● Be sure to ground the ground terminal.
(200V class: Ground to 100Ω or less, 400V class: Ground to 10Ω or less, 660V
class: Ground to 5Ω or less)
Otherwise, an electric shock or fire can occur.
● Connect input terminals (R, S, T) and output terminals (U, V, W) correctly.
Otherwise it will cause damage the inside part of inverter.
● Do not wire and operate the inverter with wet hands.
Otherwise there is a risk of electric shock.
● Check to be sure that the voltage of the main AC power supply satisfies the rated
voltage of the Inverter.
Injury or fire can occur if the voltage is not correct.
● Connect power supply cables and motor cables tightly.
