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 parts 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 inverter. In particular, keep sufficient distance between the inverter and other heat sources (e.g., braking resistors and reactors) if they are installed in the vicinity.

Wall

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.

*1 10 cm or more for 11 to 75kW 30cm or more for 90 to 160kW

*2 10 cm or more for 11 to 75kW 30cm or more for 90 to 160kW

But for exchanging the DC bus capacitor, take a distance.

22cm or more for 18.5 to 75kW 30cm or more for 90 to 160kW

(3)Ambient temperature

Avoid installing the inverter in a place where the ambient temperature goes above or below the allowable range (-10°C to +40°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 condensation.

Condensation inside the inverter will result in short circuits and malfunctioning of electronic parts. 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

Heat in the inverter rises from the under to the upper part of the inverter up with the fan built into the inverter, and make it to the one without the obstacle even if the influence of heat is received, please when you arrange apparatus up.

Moreover, please usually arrange it sideways like the left side of the figure below when you store two or more inverters in the same enclosure.

The temperature in an upper inverter rises because of the heat of a lower inverter when it places one behind another unavoidably to reduce the space of the enclosure, it causes the inverter breakdown, and set it up, please so that the heat of a lower inverter should not influence an upper inverter. Please note it enough as ventilation, ventilation, and the size of the board are enlarged so that the ambient temperature of the inverter should not exceed the permissible value when two or more inverters are stored on the enclosure.

(8) 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.

(9)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 with the heat sink positioned outside, cut out the enclosure panel according to the specified cutting dimensions.

The cooling section (including the heat sink) 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.

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 left 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.
