1. Points for Handling
Follow this manual and precautions when handling the inverter. Incorrect
handling could lead to inhibited operation or a drop operating life. In the worst
case, the inverter could be damaged.
Power supply
Use within + 10%, -15% of the tolerable input
voltage range, and with in±5% of the tolerable
input frequency range.
Circuit breaker
（MCCB）
Size a breaker from the selection table on
page 21.
Magnet contactor
（MC）
A magnetic contactor is not required in normal
use. If installed, do not start or stop the inverter
with the magnet contactor.
Power factor
improvement
reactor
Connect this when the power factor must be
improved.
Inverter
The ambient temperature is the most important
factor for the installation site.
Make sure that the tolerable value is not
exceeded. (See page 12)
Thermal relay
for open phase
protection
The thermal relay built into the inverter is used
to protect against overloads.
Use an open phase protection thermal relay
for open phase protection.
