Never
Disassemble
-Never open the front cover of the inverter(or the door of the cabinet in
which the inverter is installed) when the inverter is energized, or you
could get a shock since a high voltage is applied to certain portions of it.
-Do not put your fingers into the panel through a wiring opening or an
Prohibited
opening in the cooling fan cover, or you could get a shock or an injury.
-Do not put or insert anything(e.g., electric cable, bar or steel wire) into the
inverter, or the inverter could cause a shock or fire.
-Do not splash water over the inverter, or the inverter could cause a shock
or a fire.
-Do not turn on the power before attaching the front cover (or closing the
door of the cabinet in which the inverter is installed), or you could get a

In such a case, request your TOSHIBA dealer for repair.
-Due to the possibility of contaminants entering the drive, disconnect the
input power if the drive will be unused for extended periods.
The leakage current caused by the contamination may result in fire.

since they become very hot.
