■ Maintenance and inspection
■ Disposal
■ Sterilization, insect removal processing for wooden packaging material
■ Attach caution labels
Shown here are examples of caution labels for preventing accidents that are to be attached to inverters,
motors and other equipment.
Warning
Prohibited
• Do not replace parts.
This will result in electric shock, fire and other injury. Please call your Toshiba distributor for
repairs and replacement of expendable parts.
Mandatory
action
• Perform daily inspection and periodic inspection on equipment.
If the equipment is not inspected and maintained, faults and malfunctions cannot be discovered
and that can result in accidents.
• Before inspection, perform the following steps.
(1) Turn off the power to the inverter.
(2) Wait at least 15 minutes and verify that the charge lamp is no longer lit.
(3) Use a tester that can measure DC voltages (800 VDC or more), and verify that the voltage
to the DC main circuits between [PA/+] and [PC/-] is 45V or less, and verify that the residual
voltage of AC main circuits cable is 45V or less.
Performing inspection without carrying out these steps can lead to electric shock.
When using the PM motor, please verify that the PM motor is stopped. While the PM motor is
rotating even after the power is turned off, as a high voltage is generated in the output terminals
[U/T1], [V/T2] and [W/T3] on the PM motor side, touching the output terminals will result in
electric shock.
Caution
Mandatory
action
• If you dispose of the inverter, have it done by a specialist in industry waste disposal
*1
.
If you dispose of the inverter by yourself, this can result in explosion of capacitor or production
of noxious gases, resulting in injury.
• When you dispose of the operation panel, insulate the terminals of the lithium battery by
wrapping the terminals with tapes.
If the terminals contact with other metal or batteries, this will result in heat rising up, explosion,
and fire.
*1 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.
Caution
Mandatory
action
• If wooden packaging materials require sterilization, insect removal processing, make sure to
employ methods other than fumigation.
The fumigation processing may damage electronic parts by generated gas and steam.
Especially halogen disinfectants, such as fluorine, chlorine, bromine and iodine cause corrosion
inside the capacitors.
