Danger

Prohibited
• Do not install or operate the inverter if it is damaged or any component is missing.
This can result in electric shock or fire. Please consult your local sales agency for repairs.
• Do not place any inflammable objects nearby.
If a flame is emitted due to malfunction, it may result in a fire.
• Do not install in any location where the inverter could come into contact with water or other
fluids.
This can result in electric shock or fire.

2.
Mandatory
• Must be used in the environmental conditions prescribed in the instruction manual.
Use under any other conditions may result in malfunction.
• Must be installed in non-inflammables such as metals.
The rear panel gets very hot. If installation is in an inflammable object, this can result in fire.
• Do not operate with the front panel cover removed. This can result in electric shock.
• An emergency stop device must be installed that fits with system specifications (e.g. shut
off input power then engage mechanical brake).
Operation cannot be stopped immediately by the inverter alone, thus risking an accident or
injury.
• All options used must be those specified by Toshiba. The use of any other option may result
in an accident.

Warning

Prohibited
• When transporting or carrying, do not hold by the front panel covers.
The covers may come off and the unit will drop out resulting in injury.
• Do not install in any area where the unit would be subject to large amounts of vibration.
That could result in the unit falling, resulting in injury.
2.
1.4.4
Mandatory
• The main unit must be installed on a base that can bear the unit's weight.
If the unit is installed on a base that cannot withstand that weight, the unit may fall resulting
in injury.
• If braking is necessary (to hold motor shaft), install a mechanical brake. The brake on the
inverter will not function as a mechanical hold, and if used for that purpose, injury may
result.

■ Wiring
Danger
See item
Prohibited
• Do not connect input power to the output (motor side) terminals (U/T1,V/T2,W/T3). That will
destroy the inverter and may result in fire.
• Do not connect resistors to the DC terminals (across PA/+-PC/- or PO-PC/-). That may
cause a fire.
Connect resistors as directed by the instructions for "Installing separate braking resistors."
• Within 15 minutes after turning off input power, do not touch wires of devices (MCCB)
connected to the input side of the inverter.
That could result in electric shock.
