As shown above, there is no fuse installed in the inverter's main
circuit.
If a short circuit fault occurs in the inverter, not only MCCB2
will
trip, but the main breaker MCCB1 may also trip.
Select the shut-off characteristics of MCCB1 and MCCB2 so that a
selective shutdown can be executed and only MCCB2 trips. If the
optimum characteristics cannot be
selected, install a high-speed shut-
off fuse after MCCB2. (Refer to page 14 for MCCB
selection.)

Disposal
Precautions
Observe the following points when disposing of the inverter.
Explosions from
incineration:
Gasses from
plastics:
Disposal
method:
Placing the inverter
in
an incinerator may be dangerous, as the
electrolytic fluid used in the electrolytic capacitors may expand and
explode.
The plastic used for the cover, etc., may generate poisonous gases
when incinerated.
Commission the
disposal of the inverter to a specialist.
