• Before the connection, shut off the inverter’s power source and wait 5 min (FRN0115E2■-2

■
-4 or below, FRN0011E2
■
-7 or below) or 10 min (FRN0085E2
■
-4 or above) or more.
Furthermore, confirm that the LED monitor / charge lamp are turned off and that the DC link bus voltage of
main circuit terminals between P (+) and N (-) indicates the safety value (+25 VDC or less) by using a tester.
• A qualified specialist should perform the wiring work.
An electric shock may occur.
• In general, since the cover of the control signal line is not reinforcedly insulated, direct current flow in the
control signal line from the main circuit’s live parts, may destroy the insulation cover. If this is the case, high
voltage from the main circuit may be applied to the control lines. Be careful to avoid main circuit’s live part
comes in contact with the control signal lines.
It may cause an accident or fire.
The noise may be generated from the inverter, motor, and cables. Be careful about malfunction of surrounding
sensor and equipment.
Otherwise an accident could occur.
