* 1. Use a ground fault interrupter with a current sensitivity of 200 mA minimum and an operating time of 0.1 s minimum to prevent operating errors. The interrupter
must be suitable for high-frequency operation.
Example: NV series by Mitsubishi Electric Corporation (manufactured in or after 1988)
EG, SG series by Fuji Electric Co., Ltd. (manufactured in or after 1984)
* 2. The finement zero-phase reactor is manufactured by Hitachi Metals.
Table 9.4 Options and Peripheral Devices
Model (Code)
Always connect a breaker to the power supply line to pro-
NF tect Inverter wiring. Use a ground fault interrupter suitable
*1
for high frequencies.
Install to prevent the braking resistor from burning out
HI- J when one is used. Always attach a surge absorber to the
coil.
Absorbs surge from the magnetic contactor and control
DCR2- relays. Connect surge absorbers to all magnetic contactors
and relays near the Inverter.
Isolates the I/O signals of the Inverter and is effective
DGP
against inductive noise.
Used to improve the input power factor of the Inverter. All
Inverters of 18.5 kW or higher contain built-in DC reac-
UZDA-
tors. These are optional for Inverters of 15 kW or less.
UZBA-
Install DC and AC reactors for applications with a large
power supply capacity (600 kVA or higher).
Reduces noise coming into the inverter from the power
(Single phase) LNFB- supply line and to reduce noise flowing from the inverter
(3 phase) LNFD- HF into the power supply line. Connect as close to the
Inverter as possible.
F6045GB
Reduces noise from the line that sneaks into the Inverter
(FIL001098)
input power system. Insert as close to the Inverter as pos-
sible.
F11080GB
Can be use on both the input side and output side.
(FIL001097)
Reduces noise generated by the Inverter. Connect as close
LF-o
to the Inverter as possible.
ERF-150WJ Consumes the regenerative motor energy with a resistor to
(R00 ) reduce deceleration time (use rate: 3% ED).
LKEB- Consumes the regenerative motor energy with a resistor to
(75600-K 0) reduce deceleration time (use rate: 10% ED).
CDBR- Used with a Braking Resistor Unit to reduce the decelera-
(72600-R 0) tion time of the motor.
Allows frequency reference settings and ON/OFF opera-
JVOP-95• tion control to be performed by analog references from a
(73041-0905X- ) remote location (50 m max.).
Frequency counter specifications: 60/120 Hz, 90/180Hz
Allows frequency reference settings and ON/OFF opera-
JVOP-96• tion control to be performed by analog references from a
(73041-0906X- ) remote location (50 m max.).
Frequency counter specifications: 75 Hz, 150 Hz, 220 Hz
1 m cable: (72606-
WV001) Extension cable to use a Digital Operator remotely.
3 m cable: (72606- Cable length: 1 m or 3 m
WV003)
A system controller that can be match to the automatic
JGSM- control system to produce an optimum system configura-
tion.
Handles momentary power losses for the control power
P00 0
supply for models 2.2 kW or less (maintains power for
(73600-P00 0)
2 s).
DCF-6A
RV30YN20S (2 kΩ)
Devices to set or monitor frequencies externally.
CM-3S
Measures the output voltage externally and designed for
SCF-12NH
use with a PWM Inverter.
2 kΩ (ETX003270) Connected to the control circuit terminals to input a fre-
20 kΩ (ETX003120) quency reference.
(RH000850) Calibrates the scale of frequency meters and ammeters.
