Danger
Reference
Prohibited
-Do not install or operate the inverter if it is damaged or any part is missing
from it. Operating the inverter in a defective condition could lead to a
shock or a fire. Request your Toshiba dealer for repair.
-Do not put any inflammable material near the inverter, or it could catch a
fire if the inverter sparks because of a breakdown, etc.
-Do not install the inverter where it can be splashed with water, etc., or it
could cause a shock or a fire.

Mandatory
-Use the inverter under environmental conditions specified by this
instruction manual, or it could break down.
-Install the inverter on a non-combustible board, for example, a steel plate.
Installing it on a inflammable board or wall could lead to a fire because its
back is heated up during operation.
-Do not use the inverter with the front cover detached, or it could cause a
shock.
-Install an emergency shutdown device which matches the system (for
example, a switch interlocked with the brake of the machine). Failure to
do so could lead to injury to persons since it has no emergency stop
function.
-Do not use any optional devices other than those designated by our
company.
The use of improper devices could lead to accidents.

Warning
Reference
Prohibited
-Do not hold the front cover to carry the inverter, or the cover could come
off and cause the main unit to fall, thus causing you to get an injury.
-Do not install the inverter in any place subject to vibration, or it could fall,
causing injury to persons.
2.
1.4.4
Mandatory
-For a model (20 kg or more in weight) designed for 30kW motors or larger,
carry it at least in a twosome, or it could fall and cause you to get an
injury.
-Handle large capacity model using a crane. Lifting heavy inverter causes
injury to persons. Taking care of safety for users, carefully handle in orde
r
not to damage to the inverter.
Carefully lift up the inverter, hanging wires on the hanging bolts or halls
on the top or bottom of the inverter.
-Four points and perpendicular lifting is recommended. Even if
perpendicular lifting is impossible, respect the condition described in the
following figure. A crack may be attached to the product body when not
performing perpendicular lifting. Please be careful.
-Install the main unit on a wall, or the like, which is strong enough to
withstand its weight, or it could fall and cause injury to persons.
-Install a mechanical brake whenever the motor requires a brake (device
which retains the motor shaft). Failure to do so could lead to injury to
persons because the inverter itself has no function of mechanically
retaining the brake shaft.
