Turn the input power on only after attaching the terminal block cover.
When enclosed inside a cabinet and used with the terminal block cover removed,
always close the cabinet doors first and then turn the power on. If the power is turned
on with the terminal block cover or cabinet doors open 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, resulting in injury.
If incorrect setting, the drive may has some damage or unexpected movement. Be
sure to set the setup menu correctly.
Observe all permissible operating ranges of motors and mechanical equipment.
(Refer to the motor's instruction manual.) Not observing these ranges may result in
injury.
Use an inverter that conforms to the specifications of power supply and three-phase
induction motor being operated. If the inverter being used does not conform to those
specifications, not only will the three-phase induction motor not rotate correctly, but it
may cause serious accidents through overheating and fire.
The leakage current through the input/output power cables of inverter and
capacitance of motor may affect to peripheral devices.
The value of leakage current is increased under the condition of the PWM carrier
frequency and the length of the input/output power cables. In case the total cable
length (total of length between an inverter and motors) is more than 100m, overcurrent
trip may occur even the motor no-load current.
Make enough space among each phase cable or install the filter (MSF) as
countermeasure.
Do not replace parts. This could be a cause of electric shock, fire and bodily injury. To
replace parts, call your Toshiba distributor.
The equipment must be inspected daily. If the equipment is not inspected and
maintained, errors and malfunctions may not be discovered and that could result in
accidents.
Before inspection, perform the following steps. ; (1) Turn off all input power to the
inverter. ; (2) Wait at least 15 minutes and check to make sure that the charge lamp is
no longer lit. ; and (3) Use a tester that can measure DC voltages (400V/800V DC or
more), and check that the voltage to the DC main circuits (across PA/+ - PC/-) is 45V
or less.
Performing an inspection without carrying out these steps first could lead to electric
shock.
If you dispose of the inverter, have it done by a specialist in industry waste disposal
(*). If you dispose of the inverter by yourself, this can result in explosion of capacitor or
produce noxious gases, resulting in injury.
(*) Persons who specialize in the processing of waste and known as "industrial waste
product collectors and transporters" or "industrial waste disposal persons". Please
observe any applicable law, regulation, rule or ordinance for industrial waste disposal.
