●Do not connect a resistor directly to the DC terminals P/+, N/–. This could cause a fire and destroy the inverter. The surface temperature of braking resistors can far exceed 100°C for brief periods. Make sure that there is adequate protection against accidental contact and a safe distance is maintained to other units and system parts.
Injury prevention
CAUTION:
E ● Apply only the voltage specified in the instruction manual to each terminal. Otherwise, burst, damage, etc. may occur.
●Ensure that the cables are connected to the correct terminals. Otherwise, burst, damage, etc. may occur.
●Always make sure that polarity is correct to prevent damage, etc. Otherwise, burst, damage, etc. may occur.
●While power is on or for some time after power-off, do not touch the inverter as it is hot and you may get burnt.

Operation
WARNING:
P ● When you have chosen the retry function, stay away from the equipment as it will restart suddenly after an alarm stop.
●Since pressing STOP/RESET key may not stop output depending on the function setting status, provide a circuit and switch separately to make an emergency stop (power off, mechanical brake operation for emergency stop, etc.).
●Make sure that the start signal is off before resetting the inverter alarm. A failure to do so may restart the motor suddenly.
●The inverter can be started and stopped via the serial port communications link or the field bus. However, please note that depending on the settings of the communications parameters it may not be possible to stop the system via these connections if there is an error in the communications system or the data line. In configurations like this it is thus essential to install additional safety hardware that makes it possible to stop the system in an emergency (e.g. controller inhibit via control signal, external motor contactor etc). Clear and unambiguous warnings about this must be posted on site for the operating and service staff.
●The load used should be a three-phase induction motor only. Connection of any other electrical equipment to the inverter output may damage the inverter as well as the equipment.
●Do not modify the equipment.
●Do not perform parts removal which is not instructed in this manual. Doing so may lead to fault or damage of the inverter.
FR-F700 EC |

CAUTION:
E ● 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. Otherwise, the life of the inverter decreases.
●Use a noise filter to reduce the effect of electromagnetic interference and follow the accepted EMC procedures for proper installation of frequency inverters. Otherwise nearby electronic equipment may be affected.
●Take appropriate measures regarding harmonics. Otherwise this can endanger compensation systems or overload generators.
●Use a motor designed for inverter operation. (The stress for motor windings is bigger than in line power supply).
●When parameter clear or all clear is performed, set again the required parameters before starting operations. Each parameter returns to the initial value.
●The inverter can be easily set for high-speed operation. Before changing its setting, fully examine the performances of the motor and machine.
●The DC braking function of the frequency inverter is not designed to continuously hold a load. Use an electro-mechanical holding brake on the motor for this purpose.
●Before running an inverter which had been stored for a long period, always perform inspection and test operation.
●For prevention of damage due to static electricity, touch nearby metal before touching this product to eliminate static electricity from your body.
Diagnosis and settings
CAUTION:
E ● Before starting operation, confirm and adjust the parameters. A failure to do so may cause some machines to make unexpected motions.
Emergency stop
CAUTION:
E ● Provide a safety backup such as an emergency brake which will prevent the machine and equipment from hazardous conditions if the inverter fails.
●When the breaker on the inverter primary side trips, check for the wiring fault (short circuit), damage to internal parts of the inverter, etc. Identify the cause of the trip, then remove the cause and power on the breaker.
●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.
