the following locations (the messages are written in Japanese, English and French).
When handling the inverter, be sure to observe the instructions given on these
warning labels.

3 Precautions for use
– 10 –
3 Precautions for use
This chapter explains the limitations and other items the user must note when using
the inverter.

Selection
• Always use the inverter with Oriental Motor’s three-phase motor. Check the
permitted inverter/motor combinations in 4.2, “Motor/Inverter combinations” on
p.15.
• If a large-capacity power transformer (600 kVA or more) is connected to the
inverter, always install a DC reactor. Installing a DC reactor will improve the
power factor of the power supply. If any thyristor converter, such as a DC drive, is
connected to the inverter’s power supply, always install a DC reactor regardless of
the condition of power supply. For the peripherals that should be used with the
inverter, refer to 11.3 “Recommended peripherals” on p.58. Installing a DC
reactor will lower the DC voltage of the inverter’s main circuit. Therefore, in a
high-speed range the motor torque may drop and thereby cause the inverter’s
output current to rise beyond the rated output current.
Therefore, if you are connecting a DC reactor, keep the load to 80% of the
allowable torque or below so as not to cause the output current to exceed the rated
current.
• The explanations given in this manual assume an operating configuration
consisting of one motor and one inverter. If you need to operate multiple motors
with one inverter, please contact our Customer Service Center.
• Upon detection of abnormality, an appropriate protective function of the inverter
will actuate to automatically stop the inverter output. However, the inverter’s
protective functions cannot stop the motor quickly enough to ensure higher levels
of safety for your equipment. If your equipment requires an emergency-stop
function, provide a mechanical means for stopping the motor/retain the load.

Installation
• When installing the inverter, select a place with clean air free from oil mist, cotton
fly, dust or other suspended matters. Also, install the inverter in a fully sealed
enclosure that shuts out any suspended matters. If the inverter is installed in a
panel, select an appropriate cooling method and enclosure dimensions to keep the
inverter ambience from exceeding the allowable temperature.
• So that the heat generated from the inverter can be effectively exhausted, always
install the inverter vertically with the display side facing up. For the installation
method, refer to 5.2 “Installation condition” on p.22.

3 Precautions for use
– 11 –

Handling
• Impressing voltage on the motor terminals (U, V and W) on the rear of the
inverter may damage the inverter. Before turning on the power, confirm that the
power supply is wired correctly.
• If an electromagnetic contactor is connected between the power supply and
inverter, do not start or stop the inverter using the electromagnetic contactor.
Doing so may damage the inverter.

Peripherals
Installation and selection of protective devices
Install a protective device between the power supply and inverter to protect the
inverter’s primary circuit. For details on selecting an appropriate protective device
for this purpose, refer to 11.3 “Recommended peripherals” on p.58. Since a fully
electromagnetic molded-case circuit breaker can change the operating characteristics
of the inverter by generating harmonic current, select a breaker with a large capacity
if this type of circuit breaker is used. In the case of an earth-leakage breaker, use of a
special earth-leakage breaker for inverter, or a general earth-leakage breaker with a
current sensitivity of 200 mA or more, is recommended.
Use of an electromagnetic contactor between the power supply and
inverter
The inverter can be used without an electromagnetic contactor between the power
supply and inverter. An electromagnetic contactor is sometimes installed between
the power supply and inverter for the purpose of preventing the inverter from
starting automatically upon recovery from a momentary power outage. In this case,
do not use the electromagnetic contactor to start or stop the inverter. Doing so may
damage the inverter.
If an electromagnetic contactor is installed between the inverter and motor, as a rule
do not turn on/off the inverter power while the motor is operating. If an
electromagnetic contactor is provided to switch between the mains and other power
source, always stop the inverter and motor before switching to the mains.
If an electromagnetic contactor is used as a safety device in the event of momentary
power outage, use a delayed-release type electromagnetic contactor.

Improvement of power factor (Elimination of phase-advanced
capacitor)
To improve the power factor of the inverter, connect a DC reactor to the reactor
terminals on the inverter. Connecting a capacitor or surge killer to the inverter’s
output side for the purpose of improving the power factor may generate harmonics
in the inverter output, thus causing the motor to overheat or sustain damage. Also,
overcurrent may flow into the inverter and activate the inverter’s overcurrent
protection function. Therefore, do not connect a capacitor or surge killer to the
inverter.

3 Precautions for use
– 12 –

Radio interference
The inverter’s main circuit generates harmonics. Therefore, communication
equipment used near the inverter may suffer from radio interference. To minimize
the radio interference caused by the inverter, install a mains filter to the inverter
circuit. Radio interference can also be suppressed by housing the cables between the
inverter and motor/power supply in metal ducts and ground the metal ducts.

Cable size and wiring distance
Use a power cable of AWG14 (2.0 mm2) in size. For the wiring between the inverter
and motor, always use a dedicated optional cable (p.57). The maximum wiring
distance between the inverter and motor is 20 m (65.6 ft.) including extensions. If
the wiring distance between the inverter and motor must exceed 20 m (65.6 ft.),
please contact our Customer Service Center.
When operating the inverter via external input signals, keep the control lines as short
as possible. Also, wire the control lines away from the main circuits, relay sequence
circuits and other high-power circuits of peripherals, in order to prevent induction by
peripherals.

Noise elimination
This inverter adopts PWM control based on high carrier frequency and is therefore
subject to higher levels of electromagnetic noise. Eliminate noise by referring to the
following examples.
• Connect a mains filter to prevent sensor malfunctions and also eliminate AM radio
noise.
• To prevent negative effects by the inductive noise from the inverter’s power lines,
wire the inverter’s signal lines using twisted-pair shielded cables at least 300 mm
(11.8 in.) away from the power lines.

3 Precautions for use
– 13 –

Countermeasure against harmonic leak current
Stray capacitance exists between the inverter’s power lines and other power lines,
the ground or the connected motor. Harmonic leak current may flow from the
inverter to the motor or peripherals through this stray capacitance, giving unwanted
effects to the motor/peripherals. Since leak current is determined by the wiring
distance between the inverter and motor and also by the inverter’s carrier frequency,
provide the following measures to minimize leak current.
• Use an earth-leakage breaker incorporating harmonic elimination measures (refer
to “Recommended peripherals” on p.58).
• Set the carrier frequency to 10 kHz using the carrier-frequency selector switch
provided on the rear of the inverter.
• Connect a zero-phase reactor (p.58).
A zero-phase reactor can be connected to either the output or input side of the
inverter. It also has the effect of reducing noise.
