Power supply
Use within the permissible power supply specifications of the inverter. (Refer to page 99.)
No-fuse breaker (NFB) or earth leakage circuit braker (ELB)
The breaker must be selected carefully since an in-rush current flows in the inverter at
power-on. (Refer to page 3.)
Magnetic contactor
Install the magnetic contactor to ensure safety. (For details, refer to the Instruction Manual
(detailed).)
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 3.)
Noise filter
Install a noise filter to reduce the magnetic noise generated from the inverter.
(Refer to the instruction manual of each option for details.)
• Line noise filter (FR-BSF01) (FR-BLF)
Effective in the range from about 1MHz to 10MHz. When more wires are passed
through, a more effective result can be obtained.(Note that the number of wires run
through is limited when fitting to the output side.)
• Radio noise filter (FR-BIF)
Effective in reducing the noises in the AM radio frequency band. Dedicated filter for the
input side.
Power factor improvement reactor
Reactors must be used when the power factor is to be improved or when the inverter is
installed near a large power supply system (1000kVA or more and wiring distance is within
10m). The inverter may be damaged if you do not use reactors.
Make selection carefully. (Refer to page 3.)
(Refer to the instruction manual of each option for details.)
• DC reactor (FR-BEL), AC reactor (FR-BAL)
(Caution) Remove the jumpers across terminals P-P1 to connect to the PC reactor.
Inverter
The life of the inverter is influenced by am bient tem perature. The am bient
tem perature should be as low as possible w ithin the perm issible range. T his m ust be
noted especially w hen the inverter is installed in an enclosure. (R efer to page 6.)
W rong w iring m ight lead to dam age of the inverter. T he control signal lines m ust be
kept fully aw ay from the m ain circuit to protect them from noise. (R efer to page 7.)
Brake resistor
(Refer to the instruction manual of each option for details)
(Caution) • Remove the jumpers across terminals PR-PX to connect to the inverter.
• Set "1" in Pr. 30 "regenerative function selection".
• Set "10%" in Pr. 70 "special regenerative brake duty".
Brake unit
(Refer to the instruction manual of each option for details)
(Caution) Remove the jumpers across terminals PR-PX to connect to the inverter.
Power regeneration common converter (FR-CV)
• (Refer to the instruction manual of each option for details.)
(Caution) • Remove the jumpers across terminals R-R1 and S-S1.
• For a terminal to be connected to the RDYB signal of the FR-CV, set "10" (X10
signal) in any of Pr. 180 to Pr. 183 and Pr. 187(input terminal function selection).
• Set "2" in Pr. 30 "regenerative function selection".
• Select the converter one rank higher in capacity than the inverter.
Selection example: FR-V520-7.5K→FR-CV-11K, FR-V520-15K→FR-CV-18.5K
(When connecting two inverters to one FR-CV, the capacity is 11K + 18.5K =
29.5K. Therefore, select FR-CV-30K.)
Motor
!
Dedicated motor (Refer to page 99.)
This is a highly environmentally-resistant motor based on a totally-enclosed squirrel-
cage induction motor designed for the vector inverter. Select the motor that matches the
inverter capacity.
PLG
For the PLG dedicated motor, refer to page 12.
Devices connected to the output
Do not install a power factor correction capacitor, surge suppressor or radio noise filter (FR-
BIF option) in the output side of the inverter.
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).
