Page 5: Safety Instructions
Thank you for choosing this Mitsubishi inverter. This instruction manual provides instructions for advanced use of the FR-A700 series inverters. Incorrect handling might cause an unexpected fault. Before using the inverter, always read this instruction manual to use the equipment to its optimum.
Page 6 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.

Page 8 Wiring CAUTION: ● Do not install assemblies or components (e. g. power factor correction capacitors) on the inverter output side, which are not approved from Mitsubishi. ● The direction of rotation of the motor corresponds to the direction of rotation commands (STF/STR) only if the phase sequence (U, V, W) is maintained.
Page 9 ● When the protective function is activated (i. e. the frequency inverter switches off with an error message), take the corresponding corrective action as described in the inverter manual, then reset the inverter, and resume operation. FR-A700 EC...
Page 10 Maintenance, inspection and parts replacement CAUTION: ● Do not carry out a megger (insulation resistance) test on the control circuit of the inverter. Disposing the inverter CAUTION: ● Treat as industrial waste. General instructions Many of the diagrams and drawings in instruction manuals show the inverter without a cover, or partially open.

Page 30: Enclosure Design
Enclosure design Installation Enclosure design When an inverter enclosure is to be designed and manufactured, heat generated by contained equipment, etc., the environment of an operating place, and others must be fully considered to determine the enclosure structure, size and equipment layout. The inverter unit uses many semiconductor devices.
Page 31 If the inverter is exposed to corrosive gas or to salt near a beach, the printed board patterns and parts will corrode or the relays and switches will result in poor contact. In such places, take the measures against dust, dirt, oil mist. FR-A700 EC 2 - 7...
Page 32 Enclosure design Installation Explosive, flammable gases As the inverter is non-explosion proof, it must be contained in an explosion proof enclosure. 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).

Page 36: Heatsink Protrusion Attachment (Fr-A7Cn)
Enclosure design Installation 2.4.3 Heatsink protrusion attachment (FR-A7CN) When encasing the inverter in an enclosure, the generated heat amount in an enclosure can be greatly reduced by installing the heatsink portion of the inverter outside the enclosure. When in- stalling the inverter in a compact enclosure, etc., this installation method is recommended. For the FR-A740-00023 to 03610, a heatsink can be protruded outside the enclosure using a heatsink protrusion attachment (FR-A7CN).
Page 37 ● Having a cooling fan, the cooling section which comes out of the enclosure can not be used in the environment of waterdrops, oil, mist, dust, etc. ● Be careful not to drop screws, dust etc. into the inverter and cooling fan section. FR-A700 EC 2 - 13...

Page 98 Electromagnetic compatibility (EMC) Wiring NOTES The frequency inverter monitors its own output for ground faults up to a frequency of 120Hz. However, it is important to understand that this feature only protects the inverter itself. It can- not be used to provide protection against shock hazards for personnel. In the connection earthed-neutral system, the sensitivity current is purified against an earth fault in the inverter output side.

Operation Precautions for use of the inverter The FR-A700 series is a highly reliable product, but incorrect peripheral circuit making or op- eration/handling method may shorten the product life or damage the product. Before starting operation, always recheck the following items.
Page 106 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.
