 Never disassemble, modify or repair.
This can result in electric shock, fire and injury. Call your Toshiba distributor for repairs.
 Do not stick your fingers into openings such as cable wiring holes and cooling fan covers.
This can result in electric shock or other injury.
 Do not place or insert any kind of object (electrical wire cuttings, rods, wires) into the inverter. This can
result in electric shock or fire.
 Do not allow water or any other fluid to come in contact with the inverter.
This can result in electric shock or fire.
 When transporting or carrying, do not hold by the front panel covers.
The covers will come off and the unit will drop, resulting in injury.
 Never remove the terminal cover when power is on.
The unit contains many high voltage parts and contact with them will result in electric shock.
 Turn the power on only after attaching the terminal block cover.
If the power is turned on without the terminal block cover attached, this can result in electric shock or
other injury.
 Electrical construction work must be done by a qualified expert.
Connection of input power by someone who does not have that expert knowledge can 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 can result in injury.
 Wiring must be done after installation.
If wiring is done prior to installation, that can result in injury or electric shock.
 The following steps must be performed before wiring.
(1) Shut 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 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 block to specified torque.
If the screws are not tightened to the specified torque, it can lead to fire.
