4. Additional instructions
Also note the following points to prevent an accidental failure, injury, electric shock, etc.
(1) Transportation and installation
(2) Wiring
(3) Trial run
(4) Operation
CAUTION
z When carrying products, use correct lifting gear to prevent injury.
z Do not stack the inverter boxes higher than the number recommended.
z Ensure that installation position and material can withstand the weight of the inverter. Install according to the information in the
Instruction Manual.
z Do not operate if the inverter is damaged or has parts missing.
z Do not hold the inverter by the front cover; it may fall off.
z Do not stand or rest heavy objects on the inverter.
z Check the inverter mounting orientation is correct.
z Prevent screws, wire fragments, conductive bodies, oil or other flammable substances from entering the inverter.
z Do not drop the inverter, or subject it to impact.
z Use the inverter under the following environmental conditions:
Environment
Ambient temperature
Constant torque: -10°C to +50°C (non-freezing)
(-10°C to +40°C with totally ecclosed structure specification attachment (FR-A5CV))
Variable torque: -10°C to +40°C (non-freezing)
(-10°C to +30°C with totally ecclosed structure specification attachment (FR-A5CV))
Ambient humidity 90%RH or less (non-condensing)
Storage temperature -20°C to +65°C*
Ambience Indoors (free from corrosive gas, flammable gas, oil mist, dust and dirt)
Altitude, vibration
Maximum 1000m above sea level for standard operation.
After that derate by 3% for every extra 500m up to 2500m (91%).
5.9 m/s
2
or less (conforming to JIS C 0040)
*Temperatures applicable for a short time, e.g. in transit.
CAUTION
z Do not fit capacitive equipment such as a power factor correction capacitor, surge suppressor or radio noise filter (option FR-BIF)
to the inverter output side.
z The connection orientation of the output cables (terminals U, V, W) to the motor will affect the direction of rotation of the motor.
CAUTION
z Check all parameters, and ensure that the machine will not be damaged by a sudden start-up.
CAUTION
z When you have chosen the retry function, stay away from the equipment as it will restart suddenly after an alarm stop.
z The [STOP] key is valid only when the appropriate function setting has been made. Prepare an emergency stop switch separately.
z Make sure that the start signal is off before resetting the inverter alarm. A failure to do so may restart the motor suddenly.
z The load used should be a three-phase induction motor only. Connection of any other electrical equipment to the inverter output
may damage the equipment.
z Do not modify the equipment.
CAUTION
z The electronic overcurrent protection does not guarantee protection of the motor from overheating.
z Do not use a magnetic contactor on the inverter input for frequent starting/stopping of the inverter.
z Use a noise filter to reduce the effect of electromagnetic interference. Otherwise nearby electronic equipment may be affected.
z Take measures to suppress harmonics. Otherwise power harmonics from the inverter may heat/damage the power capacitor and
generator.
z When a 400V class motor is inverter-driven, it should be insulation-enhanced or surge voltages suppressed. Surge voltages
attributable to the wiring constants may occur at the motor terminals, deteriorating the insulation of the motor.
z When parameter clear or all clear is performed, each parameter returns to the factory setting. Re-set the required parameters
before starting operation.
z The inverter can be easily set for high-speed operation. Before changing its setting, examine the performance of the motor and
machine.
z In addition to the inverter's holding function, install a holding device to ensure safety.
z Before running an inverter which had been stored for a long period, always perform inspection and test operation.
