I
• Electrical construction 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.
Mandatory
• 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 volt-
• Ground must be connected securely.
Be Grounded
• Do not attach equipment (such as noise filters or surge absorbers) that have built-in ca-
Prohibited
Operations
• Do not touch inverter terminals when electrical power is going to the inverter even if the
• Do not touch switches when the hands are wet and do not try to clean the inverter with a
Prohibited
• Do not go near the motor in alarm-stop status when the retry function is selected.
• Turn input power on after attaching the front cover.
Mandatory
• Make sure that operation signals are off before resetting the inverter after malfunction.
Connection of input power by someone who does not have that expert knowledge may re-
sult 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 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.
If the screws are not tightened to the specified torque, it may lead to fire.
age 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.
pacitors to the output (motor side) terminals.
That could result in a fire.
motor is stopped.
Touching the inverter terminals while power is connected to it may result in electric shock.
damp cloth.
Such practices may result in electric shock.
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.
When storing inside the 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.
If the inverter is reset before turning off the operating signal, the motor may restart
suddenly causing injury.
