2 INSTALLATION AND WIRING
NOTE
y
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 to page 7)
y
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 8)
y
Do not install a power factor correction capacitor, surge suppressor or noise filter (capacitor) 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.
y
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 the FR-BIF optional noise filter
(capacitor) (for use in the input side only) or FR-BSF01 or FR-BLF noise filter (ferrite core) to minimize interference.
(
Refer to Chapter 3 of the Instruction Manual (Applied)).
y
Refer to the Instruction Manual of each option and peripheral devices for details of peripheral devices.
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 shortened.

Noise filter (ferrite core)
(FR-BSF01, FR-BLF)
Install a noise 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.

contact each manufacturer for selection of the
moulded case circuit breaker.

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.

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.
