Example of FR-E The inverter unit uses many semiconductor devices.

To ensure higher reliability and long period of operation, operate the inverter in the ambient environment that completely satisfies the equipment specifications. Refer to the following points and take adequate measures. Always operate the inverter within this temperature range.

Operation outside this range will considerably shorten the service lives of the semiconductors, parts, capacitors and others. Take the following measures so that the surrounding air temperature of the inverter falls within the specified range. Refer to page 10 Install the panel in an air-conditioned electrical chamber. Block direct sunlight. Provide a shield or similar plate to avoid direct exposure to the radiated heat and wind of a heat source. Ventilate the area around the panel well.

Do not power off the inverter. Keep the start signal of the inverter off. Avoid installing the inverter near the air outlet of an air conditioner. Too high humidity will pose problems of reduced insulation and metal corrosion. On the other hand, too low humidity may produce a spatial electrical breakdown. Take dry air into the enclosure from outside. Provide a space heater in the enclosure. Condensation causes such faults as reduced insulation and corrosion. Take the measures against high humidity in 1.

Do not power OFF the inverter. Keep the start signal of the inverter OFF. In the atmosphere where conductive powder floats, dust and dirt will cause such faults as malfunction, deteriorated insulation and short circuit in a short time. Since oil mist will cause similar conditions, it is necessary to take adequate measures.

Countermeasures Place in a totally enclosed enclosure. Take measures if the in-enclosure temperature rises. Refer to page 10 Purge air.

Pump clean air from outside to make the in-panel pressure higher than the outside-air pressure. In such places, take the measures given in Section 3. In places where explosion may be caused by explosive gas, dust or dirt, an enclosure cannot be used unless it structurally complies with the guidelines and has passed the specified tests.

This makes the enclosure itself expensive including the test charges. The best way is to avoid installation in such places and install the inverter in a non-hazardous place. If it is used at a higher place, it is likely that thin air will reduce the cooling effect and low air pressure will deteriorate dielectric strength. Vibration or impact, if less than the specified value, applied for a long time may make the mechanism loose or cause poor contact to the connectors. Especially when impact is imposed repeatedly, caution must be taken as the part pins are likely to break.

Countermeasures Provide the panel with rubber vibration isolators. Strengthen the structure to prevent the panel from resonance. Install the panel away from sources of vibration. The cooling systems are classified as follows in terms of the cooling calculation method.

Cooling System Panel Structure Comment Natural cooling Natural ventilation enclosed, open type Low in cost and generally used, but the panel size increases as the inverter capacity increases.

For relatively small capacities. Natural ventilation totally enclosed type Being a totally enclosed type, the most appropriate for hostile environment having dust, dirt, oil mist, etc. The panel size increases depending on the inverter capacity. Forced cooling Fin cooling Having restrictions on the heatsink mounting position and area, and designed for relative small capacities.

Forced ventilation For general indoor installation. Appropriate for panel downsizing and cost reduction, and often used. Heat pipe Totally enclosed type for panel downsizing. Do not mount it horizontally or any other way. NOTE When encasing multiple inverters, install them in parallel as a cooling measure. Install the inverter vertically. To ensure ease of heat dissipation and maintenance, leave at least the shown clearances around the inverter.

At least the following clearances are required under the inverter as a wiring space, and above the inverter as a heat dissipation space. When surrounding air temperature exceeds 40 C, clearances between the inverters should be 1cm or more 5cm or more for the 5. Any equipment placed above the inverter should be heat resistant. When it is inevitable to arrange them vertically to minimize space, take such measures as to provide guides since heat from the bottom inverters can increase the temperatures in the top inverters, causing inverter failures.

When mounting multiple inverters, fully take caution not to make the surrounding air temperature of the inverter higher than the permissible value by providing ventilation and increasing the panel size. Arrangement of multiple inverters Heat generated in the inverter is blown up from the bottom of the unit as warm air by the cooling fan. When installing a ventilation fan for that heat, determine the place of ventilation fan installation after fully considering an air flow.

Air passes through areas of low resistance. Make an airway and airflow plates to expose the inverter to cool air. Also separate the main circuit wire of the input side and the output side. After wiring, wire offcuts must not be left in the inverter. Wire offcuts can cause an alarm, failure or malfunction. Always keep the inverter clean. When drilling mounting holes in an enclosure etc. The output of the single-phase power input model is three-phase V.

The brake resistor can not be connected to the 0. Not available for single-phase V power input model. To use terminal 4 initial setting is current input , set "4" in any of Pr. Inrush current limit circuit 24V Output shutoff circuit U, V, W Inverter output Connect a three-phase squirrel-cage motor.

Single-phase V power input model is not compatible with DC reactor. Earth Ground For earthing grounding the inverter chassis. Must be earthed grounded.

Phase need not be matched. Never connect the power cable to the U, V, W of the inverter. Doing so will damage the inverter. Connect the motor to U, V, W. Turning ON the forward rotation switch signal at this time rotates the motor counterclockwise when viewed from the load shaft.

If the wiring distance is long between the inverter and motor, a main circuit cable voltage drop will cause the motor torque to decrease especially at the output of a low frequency. The following table indicates a selection example for the wiring length of 20m.

Selection example for use mainly in the United States. Selection example for use mainly in Europe. NOTE Tighten the terminal screw to the specified torque.

A screw that has been tighten too loosely can cause a short circuit or malfunction. A screw that has been tighten too tightly can cause a short circuit or malfunction due to the unit breakage.

Use crimping terminals with insulation sleeve to wire the power supply and motor. An electrical circuit is usually insulated by an insulating material and encased. However, it is impossible to manufacture an insulating material that can shut off a leakage current completely, and actually, a slight current flow into the case. The purpose of earthing grounding the case of an electrical apparatus is to prevent operator from getting an electric shock from this leakage current when touching it.

To avoid the influence of external noises, this earthing grounding is important to audio equipment, sensors, computers and other apparatuses that handle low-level signals or operate very fast. Therefore, these two types should be discriminated clearly, and the following work must be done to prevent the leakage current having the inverter's high frequency components from entering the malfunction prevention type earthing grounding : a If possible, use l independent earthing grounding in figure below for the inverter.

If independent earthing grounding is not available, use ll joint earthing grounding in the figure below which the inverter is connected with the other equipment at an earthing grounding point.

The lll common earthing grounding as in the figure below, which inverter shares a common earth ground cable with the other equipment, must be avoided. A leakage current including many high frequency components flows in the earth ground cables of the inverter and inverter-driven motor.

Therefore, use the independent earthing grounding and separated the earthing grounding cable of the inverter from equipments sensitive to EMI. In a high building, it may be effective to use the EMI prevention type earthing grounding connecting to an iron structure frame, and electric shock prevention type earthing grounding with the independent earthing grounding together. Earthing Grounding must conform to the requirements of national and local safety regulations and electrical codes.

Use an neutral-point earthed grounded power supply for V class inverter in compliance with EN standard. The earth ground cable should be of not less than the size indicated in the table on the previous page Inverter Other equipment I Independent earthing Not allowed When driving a V class motor by the inverter, surge voltages attributable to the wiring constants may occur at the motor terminals, deteriorating the insulation of the motor. Refer to page 96 Pr. If malfunction of fast-response current limit function occurs, disable this function.

If malfunction of stall prevention function occurs, increase the stall level. Refer to page 92 for Pr. When using the automatic restart after instantaneous power failure function with wiring length exceeding m, select without frequency search Pr. Input resistance 4. Both inst ruction.
