- Do not re move 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 inp ut single-phase power into the inverter. Otherwise, you run the ri sk of fire.

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

- Do not conn ect 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 cable s, earth-leakage breaker, and magnetic contactors that have the specified capacity (ratings). Otherwise, you run the risk of fire.

- Do not use the magnetic conta ctor 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.

3. Operation

WARNING

- While p ower is supplied to the inverter, do not touch any terminal or internal part of the inverter, check signals, or connect or disconnect any wire or connector. Otherwise, you run the risk of electric shock or fire.

- Be sure to clo se the terminal block cover before turning on the inverter power. Do not open the terminal block cover while power is being supplied to the inverter o r voltage remains inside. Ot herwise, you run the risk of electric shock.

- Do not operate switches with wet hands. Otherwise, you run the risk of electric shock.

- While power is supplied to the inverte r, do not touch the terminal of the inverter, even if it has stopped. Otherwise, you run the risk of injury or fire.

- If the retry mode has been selected, the inverter will restart suddenly after a break in the tripping status. Stay away from the machine controlled by the inverter when the inverter is under such circumstances. (Design the machine so that human safety can be ensured, even when the inverter restarts suddenly.) Otherwise, you run the risk of injury.

- Do not select the retry mode for controlling an elevating or traveling device because output free-running status occurs in retry mode. Otherwise, you run the risk of injury or damage to the machine controlled by the inverter .

- If an operatio n command has been input to the inverter before a short-term power failure, the inverter may restart operation after the power recovery. If such a restart may put persons in danger, design a control circuit that disables the inverter from restarting after power recovery. Otherwise, you run the risk of injury.

- The [STOP] key is effective only when its function is enabled by setting. Prepa re an emergency stop switch separately. Otherwise, you run the risk of injury.

- If an operation command has been input to the inverter before the inverter enters alarm status, the inverter will restart suddenly when the alarm status is reset. Before resetting the alarm status, make sure that no operation command has been input.

- While power is supplied to the inverter, do not touch any internal part of the inverter or insert a bar in it. Otherwise, you run the risk of electric shock or fire.

2.1.1 Precautions for installation

(1) Transportation The inverter uses plastic parts. When carrying the inverter, 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 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.

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

allowable range (-10°C to +45°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.

(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.

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 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.
