Danger
Mandatory
• Electrical installation work must be done by a qualified expert.
Connection of input power by someone who does not have that expert knowledge may result in fire or
electric shock.
• Connect output terminals (motor side) correctly.
If the phase sequence is incorrect, the motor will operate in reverse and that may result in injury.
• Wiring must be done after installation.
If wiring is done prior to installation that may result in injury or electric shock
• The following steps must be performed before wiring.
(1) Turn off all input power.
(2) Wait at least ten minutes and check to make sure that the charge lamp is no longer lit.
(3) Use a tester that can measure DC voltage (800VDC 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.
• Tighten the screws on the terminal board to specified torque.
If the screws are not tightened to the specified torque, it may lead to fire.
• Check to make sure that the input power voltage is +10%, -15% of the rated power 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.
Be Grounded
• Ground must be connected securely.
If the ground is not securely connected, it could lead to electric shock or fire when a malfunction or
current leak occurs.
Warning
Prohibited
• Do not attach equipment (such as noise filters or surge absorbers) that have built-in capacitors to the
output (motor side) terminals.
That could result in a fire.
Q Operations
Danger
Prohibited
• Do not touch inverter terminals when electrical power is going to the inverter even if the motor is
stopped.
Touching the inverter terminals while power is connected to it may result in electric shock.
• Do not touch switches when the hands are wet and do not try to clean the inverter with a damp cloth.
Such practices may result in electric shock.
• Do not go near the motor in alarm-stop status when the retry function is selected.
The motor may suddenly restart and that could result in injury.
Take measures for safety, e.g. attaching a cover to the motor, against accidents when the motor
unexpectedly restarts.
Mandatory
• Turn input power on after attaching the front cover.
When installed inside a cabinet and using with the front cover removed, always close the cabinet doors
first and then turn power on. If the power is turned on with the front cover or the cabinet doors open, it
may result in electric shock.
• Make sure that operation signals are off before resetting the inverter after malfunction.
If the inverter is reset before turning off the operating signal, the motor may restart suddenly causing
injury.
