Thank you for choosing this Mitsubishi Inverter.
1. Electric Shock Prevention 2. Fire Prevention 3. Injury Prevention 4. Additional Instructions Also the following points must be noted to prevent an accidental failure, injury, electric shock, etc.
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 and the Instruction Manual (basic) [IB-0600225ENG] packed with the product carefully to use the equipment to its optimum.
This section is specifically about safety matters
Do not attempt to install, operate, maintain or inspect the inverter until you have read through Instruction Manual (Basic) and appended documents carefully and can use the equipment correctly. Do not use the inverter until you have a full knowledge of the equipment, safety information and instructions. In this Instruction Manual, the safety instruction levels are classified into "WARNING" and "CAUTION". Incorrect handling may cause hazardous conditions, resulting in death or severe injury. Incorrect handling may cause hazardous conditions, resulting in medium or slight injury, or may cause only material damage. The level may even lead to a serious consequence according to conditions. Both instruction levels must be followed because these are important to personal safety.
- 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 or wiring cover removed. Otherwise you may access the exposed high-voltage terminals or the charging part of the circuitry and get an electric shock.
- Even if power is off, do not remove the front cover except for wiring or periodic inspection. You may accidentally touch the charged inverter circuits and get an electric shock.
- Before wiring, inspection or switching EMC filter ON/OFF connector, power must be switched OFF. To confirm that, LED indication of the operation panel must be checked. (It must be OFF.) Any person who is involved in wiring, inspection or switching EMC filter ON/OFF connector shall wait for at least 10 minutes after the power supply has been switched OFF and check that there are no residual voltage using a tester or the like. The capacitor is charged with high voltage for some time after power OFF, and it is dangerous.
- This inverter must be earthed (grounded). Earthing (grounding) must conform to the requirements of national and local safety regulations and electrical code (NEC section 250, IEC 536 class 1 and other applicable standards). A neutral-point earthed (grounded) power supply for 400V class inverter in compliance with EN standard must be used.
- Any person who is involved in wiring or inspection of this equipment shall be fully competent to do the work.
- The inverter must be installed before wiring. Otherwise you may get an electric shock or be injured.
- Setting dial and key operations must be performed with dry hands to prevent an electric shock. Otherwise you may get an electric shock.
- Do not subject the cables to scratches, excessive stress, heavy loads or pinching. Otherwise you may get an electric shock.
- Do not replace the cooling fan while power is on. It is dangerous to replace the cooling fan while power is on.
- Do not touch the printed circuit board or handle the cables with wet hands. Otherwise you may get an electric shock.
- When measuring the main circuit capacitor capacity ( Pr. 259 Main circuit capacitor life measuring = "1"), the DC voltage is applied to the motor for 1s at powering off. Never touch the motor terminal, etc. right after powering off to prevent an electric shock.
WARNING
CAUTION
CAUTION
WARNING
- Inverter must be installed on a nonflammable wall without holes (so that nobody touches the inverter heatsink on the rear side, etc.). Mounting it to or near flammable material can cause a fire.
- If the inverter has become faulty, the inverter power must be switched OFF. A continuous flow of large current could cause a fire.
- When using a brake resistor, a sequence that will turn OFF power when a fault signal is output must be configured. Otherwise the brake resistor may overheat due to damage of the brake transistor and possibly cause a fire.
- Do not connect a resistor directly to the DC terminals P/+ and N/-. Doing so could cause a fire.
- The voltage applied to each terminal must be the ones specified in the Instruction Manual. Otherwise burst, damage, etc. may occur.
- The cables must be connected to the correct terminals. Otherwise burst, damage, etc. may occur.
- Polarity must be correct. Otherwise burst, damage, etc. may occur.
- While power is ON or for some time after power-OFF, do not touch the inverter since the inverter will be extremely hot. Doing so can cause burns.
(1) Transportation and installation
- The product must be transported in correct method that corresponds to the weight. Failure to do so may lead to injuries.
- Do not stack the boxes containing inverters higher than the number recommended.
- The product must be installed to the position where withstands the weight of the product according to the information in the Instruction Manual.
- Do not install or operate the inverter if it is damaged or has parts missing. This can result in breakdowns.
- When carrying the inverter, do not hold it by the front cover or setting dial; it may fall off or fail.
- Do not stand or rest heavy objects on the product.
- The inverter mounting orientation must be correct.
- Foreign conductive objects must be prevented from entering the inverter. That includes screws and metal fragments or other flammable substance such as oil.
- As the inverter is a precision instrument, do not drop or subject it to impact.
- The inverter must be used under the following environment: Otherwise the inverter may be damaged.
*1 Temperature applicable for a short time, e.g. in transit. *2 2.9m/s^2 or less for the 160K or higher.

Installation of the inverter and enclosure
design
1.4 Installation of the inverter and 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. To ensure higher reliability and long period of
operation, operate the inverter in the ambient environment that completely satisfies the equipment specifications.
1.4.1 Inverter installation environment................................................................................................
As the inverter installation environment should satisfy the standard specifications indicated in the following table,
operation in any place that does not meet these conditions not only deteriorates the performance and life of the
inverter, but also causes a failure. Refer to the following points and take adequate measures.
- 2.9m/s 2 or less for the 160K or higher.
(1) Temperature
The permissible surrounding air temperature of the inverter is between -10°C 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 measures so that the surrounding air temperature of
the inverter falls within the specified range.
1) Measures against high temperature
- Use a forced ventilation system or similar cooling system. (Refer to page 10.)
- Install the enclosure 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 enclosure well.
2) Measures against low temperature
- Provide a space heater in the enclosure.
- Do not power OFF the inverter. (Keep the start signal of the inverter OFF.)
3) Sudden temperature changes
- Select an installation place where temperature does not change suddenly.
- Avoid installing the inverter near the air outlet of an air conditioner.
- If temperature changes are caused by opening/closing of a door, install the inverter away from the door.
(2) 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" is defined as humidity 45 to
1) Measures against high humidity
- Make the enclosure enclosed, and provide it with a hygroscopic agent.
- Take dry air into the enclosure from outside.
- Provide a space heater in the enclosure.
2) Measures against low humidity
What is important in fitting or inspection of the unit in this status is to discharge your body (static electricity)
beforehand and keep your body from contact with the parts and patterns, besides blowing air of proper humidity into
the enclosure from outside.
3) Measures against condensation
Condensation may occur if frequent operation stops change the in-enclosure temperature suddenly or if the outside-
air temperature changes suddenly.
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.)

OUTLINE
(3) Dust, dirt, oil mist
Dust and dirt will cause such faults as poor contact of contact points, reduced insulation or reduced cooling effect due
to moisture absorption of accumulated dust and dirt, and in-enclosure temperature rise due to clogged filter.
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.)
Pump clean air from outside to make the in-enclosure pressure higher than the outside-air pressure.
(4) Corrosive gas, salt damage
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 given in Section (3).
(5) 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).
The best way is to avoid installation in such places and install the inverter in a non-hazardous place.
(6) Highland
Use the inverter at the altitude of within 1000m.
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.
(7) Vibration, impact
The vibration resistance of the inverter is up to 5.9m/s^2 (2.9m/s 2 for the 160K or higher) at 10 to 55Hz frequency and
1mm amplitude for the directions of X, Y, Z axes.
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 enclosure with rubber vibration isolators.
- Strengthen the structure to prevent the enclosure from resonance.
- Install the enclosure away from sources of vibration.
