10-2 Separately Installed Options
Name (Type) Explanation Installation Position
Arrester
(CN23232)
(CN2324E)
Absorbs power surges from the power source and protects the
whole equipment connected to the power source.
EMC compliance filter
(FS5536-[][]-07)
EFL-[][]SP-2
(EFL-[][][]G11-4 )
(RF3[][][]-F11)
An exclusive filter to conform to the EMC Directive
(emissions) in European standard.
Note: Refer to the "Installation Manual" when installing the
filter.
Output circuit filter
(OFL-[][][]-2)
(OFL-[][][]-4)
(OFL-[][][]-4A)
Connected to the output circuit of the low-noise type inverter
(Carrier frequency :8kHz to 15kHz, 6kHz when exceeding 40HP)
and used for the following purposes.
Voltage vibration suppression at the motor terminals.
Prevent damage to the motor insulation by surge voltage for
the 460V series inverter.
Leakage current reduction on the output side wiring.
Reduce leakage current by parallel operation by multiple
motors or long-distance wiring.
- Length of wiring should be 1300ft (400m) or less.
To reduce induced noise and radiating noise from output
wiring. Effective in long-distance wiring such as plant lines.
Note 1 : When OFL-[][][]-2 or OFL-[][][]-4 is connected, the setting
value of the carrier frequency (F26) should be set to
8kHz or more. (6kHz or more when exceeding 40HP.)
Note 2 : There is no restriction of carrier frequency (F26) when
connecting the OFL-[][][]-4A
.
(For power coordination)
Used when the capacity of the power supply transformer
exceeds 500kVA and exceeds the rated capacity of the
inverter tenfold.
Used when a thyristor converter is connected as a common
load on the same transformer.
- If the commutating reactor is not used for the thyristor
converter, an AC reactor is necessary at the inverter input
side. Confirm.
Used to prevent an inverter OV trip from occurring when the
phase advanced capacitor in the power line is switched on
and off.
Used when the voltage imbalance exceeds 2%.
( Max. Voltage [V] - Min. Voltage [V] )
= x67%
3-phase average voltage [V]
DC reactor
(DCR2-[][][])
(DCR4-[][][])
(For improving the input power-factor and reducing harmonics)
Used to reduce the harmonic current (improvement of
power-factor).
* For details on the degree of reduction, see the materials
attached to the guidelines, etc.
