2 INSTALLATION AND WIRING
NOTE
The life of the inverter is influenced by surrounding air temperature. The surrounding air temperature should be as low as
possible within the permissible range. This must be noted especially when the inverter is installed in an enclosure. (Refer
Wrong wiring might lead to damage of the inverter. The control signal lines must be kept fully away from the main circuit
to protect them from noise. (Refer to page 9)
Do not install a power factor correction capacitor, surge suppressor or capacitor type filter on the inverter output side.
This will cause the inverter to trip or the capacitor and surge suppressor to be damaged. If any of the above devices are
connected, immediately remove them.
Electromagnetic wave interference
The input/output (main circuit) of the inverter includes high frequency components, which may interfere with the
communication devices (such as AM radios) used near the inverter.  In this case, install options among the capacitor type
EMC filter FR-BIF (for use in the input side only), the ferrite core type EMC filter FR-BSF01/FR-BLF, filterpack, and EMC
filter to minimize the interference. (
Refer to Chapter 3 of the Instruction Manual (Applied)).
Refer to the instruction manual of each option and peripheral devices for details of peripheral devices.
EMC filter (ferrite core)
(FR-BSF01, FR-BLF)
Install an EMC filter (ferrite core) 
 to reduce the electromagnetic 
noise generated from the inverter.
Effective in the range from about 
1MHz to 10MHz. A wire should be 
wound four turns at a maximum.

Devices connected to the output
Do not install a power factor correction capacitor, 
surge suppressor or capacitor type filter on the output 
side of the inverter. When installing a moulded case 
circuit breaker on the output side of the inverter, 
contact each manufacturer for selection of the 
moulded case circuit breaker.
The regenerative braking capability 
of the inverter can be exhibited fully.
Install this as required.
Power supply harmonics 
can be greatly suppressed.
Install this as required.

AC power supply
Use within the permissible power supply 
specifications of the inverter. To ensure 
safety, use a moulded case circuit breaker, 
earth leakage circuit breaker or magnetic 
contactor to switch power ON/OFF.
Magnetic contactor (MC)
Install the magnetic contactor to ensure 
safety. Do not use this magnetic contactor 
to start and stop the inverter. Doing so will 
cause the inverter life to be shorten.
Moulded case circuit breaker 
(MCCB) or earth leakage circuit 
breaker (ELB), fuse
The breaker must be selected carefully 
since an in-rush current flows in the 
inverter at power ON. 
Install an EMC filter (ferrite core)  
to reduce the electromagnetic 
noise generated from the 
inverter. Effective in the range 
from about 1MHz to 10MHz. 
When more wires are passed 
through, a more effective result 
can be obtained. A wire should 
be wound four turns or more.
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 earthing cable by returning it to the earth 
(ground) terminal of the inverter.

Reactor (FR-HAL, FR-HEL option)
Reactors (option) must be used when 
power harmonics measures are taken, 
the power factor is to be improved or the 
inverter is installed near a large power 
supply system (500kVA or more). The 
inverter may be damaged if you do not 
use reactors. Select the reactor according 
to the model. Remove the jumpers across 
terminals P/+ and P1 to connect the DC reactor.
