Electric Shock Prevention WARNING: ● While power is on or when the inverter is running, do not open the front cover. Otherwise you may get an electric shock. ● Do not run the inverter with the front cover removed. Otherwise, you may access the exposed high-voltage terminals or the charging part of the circuitry and get an electric shock.

● As the inverter is a precision instrument, do not drop or subject it to impact. ● If halogen-based materials (fluorine, chlorine, bromine, iodine, etc.) infiltrate into a Mitsubishi Electric product, the product will be damaged. Halogen-based materials are often included in fumigant, which is used to sterilize or disinfect wooden packages. When...

CAUTION: ● The electronic thermal relay function does not guarantee protection of the motor from overheating. It is recommended to install both an external thermal and PTC thermistor for overheat protection. ● Do not use a magnetic contactor on the inverter input for frequent starting/stopping of the inverter.

Mounting Installation NOTE When encasing multiple inverters, install them in parallel as a cooling measure. Leave enough clearances around the inverter (refer to page 2-11). Fig. 2-8: Good heat dissipation is achieved through the vertical alignment of the frequency inverter, the side-by-side mounting and maintenance of minimum clearances.
Temperature applicable for a short time, e.g. in transit. Temperature The permissible ambient temperature of the inverter FR-E700 SC is between 10 and +50 °C. 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 meas- ures so that the ambient temperature of the inverter falls within the specified range.
Page 32
Enclosure design Installation Humidity Normally operate the inverter within the 45 to 90% range of the ambient humidity. 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. The insulation distance specified in JEM1103 "Control Equipment Insulator"...

Especially when impact is imposed repeatedly, caution must be taken as the part pins are likely to break. ● Countermeasures – Provide the enclosure with rubber vibration isolators. – Strengthen the structure to prevent the enclosure from resonance. – Install the enclosure away from sources of vibration.

Page 34
Enclosure design Installation Cooling system types for inverter enclosure From the enclosure that contains the inverter, the heat of the inverter and other equipment (trans- formers, lamps, resistors, etc.) and the incoming heat such as direct sunlight must be dissipated to keep the in-enclosure temperature lower than the permissible temperatures of the in-enclosure equipment including the inverter.
Mount the inverter on a wall as specified. Do not mount it horizontally or any other way. Above the inverter Heat is blown up from inside the inverter by the small fan built in the unit. Any equipment placed above the inverter should be heat resistant. FR-E700 SC EC/ENE 2 - 11...
Page 36
Enclosure design Installation Arrangement of multiple inverters When multiple inverters are placed in the same enclosure, generally arrange them horizontally as shown in the figure (a). 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.

Inverter and peripheral devices Wiring NOTES The life of the inverter is influenced by ambient temperature. The ambient temperature should be as low as possible within the permissible range. Especially when mounting the inverter inside an enclosure, take cautions of the ambient temperature. (Refer to section 2.4.2.) Wrong wiring might lead to damage of the inverter.
When the breaker on the inverter primary side trips, check for the wiring fault (short circuit), dam- age to internal parts of the inverter, etc. Identify the cause of the trip, then remove the cause and power on the breaker. FR-E700 SC EC/ENE 3 - 3...

(FR-E700 SC ENE) 3.7.1 Ethernet communication overview The FR-E700 SC ENE inverter is equipped with an Ethernet board. Communication with network de- vices can be made via Ethernet by connecting an Ethernet cable to the Ethernet connector on the Ethernet board.
Interface RJ-45 Number of interfaces available IP version IPv4 Tab. 3-17: Ethernet communication specifications of FR-E700 SC ENE Ethernet connector FR-E700SC-ENE Ethernet connector Fig. 3-26: Position of the Ethernet connector ● Connection cable Use Ethernet cables compliant with the following standards.
Wiring System configuration for Ethernet communication (FR-E700 SC ENE) ● Handling of the Ethernet cable – Do not touch the conductors of the cable or the connector on the inverter. Keep the conduc- tors free of dust or dirt. Handling the conductors with oily hands or dust/dirt adhesion to the conductors may cause transmission losses and impair normal data link operation.
System configuration for Ethernet communication (FR-E700 SC ENE) Wiring 3.7.4 Removal of the Ethernet board The Ethernet board is installed in the initial status. Before wiring cables to the control circuit terminals or to the main circuit terminals on the FR-E740-170SC or lower or FR-E720S-050SC or lower inverter, remove the Ethernet board as follows.
Since repeated inrush currents at power on will shorten the life of the converter circuit (switching life is about 1,000,000 times.), frequent starts and stops of the MC must be avoided.

When the wiring length is long (50 m or more) for the 400 V class small-capacity model (FR-E700-170SC or less), the external thermal relay is likely to op- erate unnecessarily because the ratio of the leakage current to the rated motor current increases.

Electromagnetic compatibility (EMC) Wiring 3.9.2 Inverter-generated noises and their reduction techniques Some noises enter the inverter to malfunction it and others are radiated by the inverter to malfunction peripheral devices.

Electromagnetic compatibility (EMC) Wiring Noise Measures Propagation Path When devices that handle low-level signals and are liable to malfunction due to noises, e.g. instru- ments, receivers and sensors, are contained in the enclosure that contains the inverter or when their signal cables are run near the inverter, the devices may be malfunctioned by air-propagated noises.

Precautions for use of the inverter Operation ● A short circuit or earth fault on the inverter output side may damage the inverter modules. – Fully check the insulation resistance of the circuit prior to inverter operation since repeated short circuits caused by peripheral circuit inadequacy or an earth fault caused by wiring inadequacy or reduced motor insulation resistance may damage the inverter modules.
Page 95
However, decreasing current will result in insufficient torque and the inverter may not start. Therefore, choose the inverter which has enough allowance for current (up to 2 rank larger in capacity). ● Make sure that the specifications and rating match the system requirements.
