Peripheral Devices Selection
Check the motor capacity of the inverter you purchased. Appropriate
peripheral devices must be selected according to the capacity. Refer
to the following list and prepare appropriate peripheral devices:
9-1 Peripheral Devices Description
Peripheral Devices
Name
Description
Moulded case circuit
break (MCCB) or earth
leakage circuit break
(ELB),fuse
The breaker must be selected carefully since an
In-rush curreH flows in the inverter at power on.
Magnetic coHactor
(MC)
Install the MC to ensure safety.
Do not use this MC to start and stop the inverter.
Doing so will cause the inverter life to be shorten.
AC/DC Reactor
Reactor (option) should be used when power
harmonics measures are taken, the power factor
is to be improved or thr inverter is installed
near a large power supply system (1000KVA or
more). The inverter may be damaged if you do
not use reactors. Select the reactor according to
the model. For the 160KW or less, remove the
jumpers across terminals P/+--P/-to connect to
the DC reactor. For the 185KW or more , a DC
reactor is supplied. Please always install the
reactor.
