I
Wiring
• Do not connect input power to the output (motor side) terminals (U/T1,V/T2,W/T3).
• Do not connect resistors to the DC terminals (across PA/+ - PC/- or PO-PC/-).
• Within 15 minutes after turning off input power, do not touch wires of devices (MCCB)
Prohibited
• When supplying power from a wall socket, do not exceed the rated capacity of the socket.
• Electrical installation work must be done by a qualified expert.
• Connect output terminals (motor side) correctly.
• Wiring must be done after installation.
• The following steps must be performed before wiring.
Instruction
• Tighten the screws on the terminal board to specified torque.
• Check to make sure that the input power voltage is +10%, -15% of the rated power
• Ground must be connected securely.
Be Grounded
• Do not attach equipment (such as noise filters or surge absorbers) that have built-in
Prohibited
That will destroy the inverter and may result in fire.
That may cause a fire.
connected to the input side of the inverter.
That could result in electric shock.
Otherwise, this may generate excessive heat which can start a fire.
Connection of input power by someone who does not have that expert knowledge may
result in fire or electric shock.
If the phase sequence is incorrect, the motor will operate in reverse and that may result in
injury.
If wiring is done prior to installation that may result in injury or electric shock
(1) Turn off all input power.
(2) Wait at least 15 minutes and check to make sure that the charge lamp is no longer lit.
(3) Use a tester that can measure DC voltage (400VDC or more), and check to make sure
that the voltage to the DC main circuits (across PA/+ - PC/-) is 45V or less.
If these steps are not properly performed, the wiring will cause electric shock.
If the screws are not tightened to the specified torque, it may lead to fire.
voltage written on the rating label (±10% when the load is 100% in continuous operation).
If the input power voltage is not +10%, -15% of the rated power voltage (±10% when the
load is 100% in continuous operation) this may result in fire.
If the ground is not securely connected, it could lead to electric shock or fire when a
malfunction or current leak occurs.

That could result in a fire.
