The inverter uses plastic parts. When carrying the inve rter, handle it carefully to prevent damage to the

parts.

Do not carry the inverter by holding the front or terminal block cover. Doing so may cause the inverter

to fall. Do not install and operate the inverter if it is damaged or its p arts are missing.

(2) Surface on which to install the inverter
The inverter will reach a high temperature (up to about 150°C) during operation. Install the inverter on

a vertical wall surface made of nonflammable material (e.g., metal) to avoid the risk of fire.

Leave sufficient space around the inverte r. In particular, keep sufficient distance between the in verter

and other heat sources (e.g., braking resistors and reactors) if they are installed in the vicinity.

Keep enough clearance between the
inverter and the wiring ducts located
above and below the inverter to prevent
the latter from obstructing the ventilation
of the inverter.

*2 10 cm or more

A

clearance of 22 cm or more is required

for replacing the DC bus capacitors.

(3) Ambient temperature
Avoid installing the inverter in a place where the ambient temperature goes above or below the

allowable range (-10°C to +50°C), as defined by the standard inverter specification.

Measure the temperature in a position about 5 cm distant from the bottom-center point of the inverter,

and check that the measured temperature is within the allowable range.

Operating the inverter at a temperature outside this range will shorten the inverter life (especially the

capacitor life).

(4) Humidity
Avoid installing the inverter in a place where the relative humidity goes above or below the allowable

range (20% to 90% RH), as defined by the standard inverter specification.
Avoid a place where the inverter is subject to con densation.
Condensation inside the inverter will result in short circuits and malfunctioning of electronic p arts. Also

avoid places where the inverter is exposed to direct sunlight.

(5) Ambient air
Avoid installing the inverter in a place where the inverter is subject to dust, corrosive gases,

combustible gases, flammable gases, grinding fluid mist, or salt water.
Foreign particles or dust entering the inverter will cause it to fail. If you use the inverter in a

considerably dusty environment, install the inverter inside a totally enclosed panel.

Chapter 2 Installation and Wiring

(6) Installation method and position
Install the inverter vertically and securely with screws or bolts on a surface that is free from vibrations

and that can bear the inverter weight.

If the inverter is not installed vertically, its cooling performance may be degraded and tripping or

inverter damage may result.

(7) Mounting in an enclosure
When mounting multiple inverters in an enclosure with a ventilation fan, carefully design the layout of

the ventilation fan, air intake port, and inverters.

An inappropriate layout will reduce the inverter-cooling effect and raise the ambient temperature. Plan

the layout so that the inverter ambient temperature will remain within the allowable range.

(Unacceptable)

Position of ventilation fan

(8) Reduction of enclosure size
If you mount the inverter inside an enclosure such that the heat sink of the inverter is positioned

outside the enclosure, the amount of heat produced inside the enclosure can be reduced and likewise
the size of the enclosure.

Mounting the inverter in an enclosure with the heat sink positioned outside requires an optional

dedicated special metal fitting.

To mount the inverter in an enclosure wit h the heat si nk positioned o utside, cut out the enclosure p anel

according to the specified cutting dimensions.

The cooling section (including the heat si nk) positioned outside the enclosure has a cooling fan.

Therefore, do not place the enclosure in any environment where it is exposed to waterdrops, oil mist,
or dust.

(9) Approximate loss by inverter capacity

2.2 Wiring

WARNING

- Be sure to ground the inverter. Otherwise, you run the risk of electric shock or fire.

- Commit wiring work to a qualified electrician. Otherwise, you run the risk of electric shock or fire.

- Before wiring, make sure that the power supply is off. Otherwise, you run the risk of electric shock or
fire.

- Perform wiring only after installing the inverter. Otherwise, you run the risk of electric shock or injury.

- Do not remove rubber bushings from the wiring section. Otherwise, the edges of the wiring cover may
damage the wire, resulting in a short circuit or ground fault.

！

CAUTION

- Make sure that the voltage of AC power supply matches the rated voltage of your inverter. Otherwise,
you run the risk of injury or fire.

- Do not input single-phase power into the inverter. Otherwise, you run the risk of fire.

- Do not connect AC power supply to any of the output terminals (U, V, and W). Otherwise, you run the
risk of injury or fire.

- Do not connect a resistor directly to any of the DC terminals (PD, P, and N). Otherwise, you run the
risk of fire.

- Connect an earth-leakage breaker to the power input circuit. Otherwise, you run the risk of fire.

- Use only the power cables, earth-leakage breaker, and magnetic contactors that have the specified
capacity (ratings). Otherwise, you run the risk of fire.

- Do not use the magnetic contactor installed on the primary and secondary sides of the inverter to stop
its operation.

- Tighten each screw to the specified torque. No screws must be lef t loose. Otherwise, you run the risk
of fire.

- Before operating, slide switch SW1 in the inverter, be sure to turn off the power supply. Otherwise, you
run the risk of electric shock and injury.

- Since the inverter supports two modes of cooling-fan operation, the inverter power is not always off,
even when the cooling fan is stopped. Therefore, be sure to confirm that the power supply is off before
wiring. Otherwise, you run the risk of electric shock and injury.
