CONNECTION OF PERIPHERAL DEVICES
1.1 Basic configuration
(NFB)
or (ELB)
(MC)
AC reactor
(FR-BAL)
Earth (Ground)
Earth
(Ground)
Power supply
Use within the permissible power supply
specifications of the inverter. (Refer to page 62.)
No-fuse breaker or earth leakage circuit breaker
The breaker must be selected carefully since an in-
rush current flows in the inverter at power on.
Magnetic contactor
Install for your safety. Do not use this magnetic
contactor to start and stop the inverter. Doing so will
cause the inverter life to be shorten. (Refer to page
12.)
Installation of a reactor
A reactor must be used when the power factor is to
be improved or the inverter is installed near a large
supply system (500kVA or more and wiring distance
within 10 m).
Make the selection carefully.
The life of the inverter is influenced by ambient
temperature. Check the ambient temperature.
Epecially when mounting the inverter inside an
enclosure, take cautions of the ambient
temperature. (Refer to page 64.)
DC reactor
Wrong wiring might lead to damage of the inverter.
(FR-BEL)
The control signal wires must be kept fully away
from the main circuit to protect them from noise.
(Refer to page 5.)
Devices connected to the output
Do not install a power factor correction capacitor,
surge suppressor or radio noise filter on the output
side of the inverter.
When installing a no-fuse breaker on the output side
of the inverter, contact each manufacturer for
selection of the no-fuse breaker.
Earth (Ground)
To prevent an electric shock, always earth (ground)
the motor and inverter.
For reduction of induction noise from the power line
of the inverter, it is recommended to wire the earth
(ground) cable by returning it to the earth (ground)
terminal of the inverter.
(For details of noise reduction techniques, refer to
the instruction manual (detailed).)
