1.2 Precautions
1.2.1 Motor Insulation Inspection
When the motor is used for the first time or when the motor is reused after being kept, or when
periodical inspection is performed, insulation inspection shall be conducted with motor so as to avoid
damaging the inverter because of the insulation failure of the motor windings. The motor wires must be
disconnected from the inverter during the insulation inspection. It is recommended to use the 500V
mega meter, and the insulating resistance measured
shall be 5MΩ at least.
1.2.2 Motor Thermal Protection
If the motor rating does not match that of the inverter, especially when the rated power of the
inverter is higher than that of the motor, adjust motor protection parameters in the inverter or install
thermal relay to protect motor.
1.2.3 Operating with the Frequency Higher than Grid Power Frequency
Output frequency of FR200 is 0.00Hz
～
600.00Hz. If FR200 is required to operate above 50.00Hz,
please take the endurance of mechanical devices into consideration.
1.2.4 Mechanical Vibrations
Inverter may encounter mechanical resonance point of the load device at certain output
frequencies which can be avoided by setting the skip frequency parameters of the inverter.
1.2.5 Motor Heat and Noise
Since output voltage of inverter is PWM wave and contains a certain amount of harmonics, so
that the temperature, noise and vibration of the motor will be higher than those when the inverter runs
at grid power frequency.
1.2.6
Voltage-sensitive device or capacitor on output side of the AC drive
Do not install the capacitor for improving power factor or lightning protection voltage-sensitive
resistor on the output side of the AC drive because the output of the AC drive is PWM wave.
Otherwise, the AC drive may suffer transient overcurrent or even be damaged.
1.2.7 Contactor at the I/O terminal of the AC drive
When a contactor is installed between the input side of the AC drive and the power supply, the AC
drive must not be started or stopped by switching the contactor on or off. If the AC drive has to be
operated by the contactor, ensure that the time interval between switching is at least one hour since
frequent charge and discharge will shorten the service life of the capacitor inside the AC drive.
When a contactor is installed between the output side of the AC drive and the motor, do not turn off the
contactor when the AC drive is active. Otherwise, modules inside the AC drive may be damaged.
1.2.8 Applied with the Rated Voltage
Apply FR200 with the rated voltage. Failure to comply will damage inverter. If required, take a
transformer to boost or step-down voltage.
1.2.9 Do Not Apply a 3-Phase Input Inverter to 2-Phase Input Applications
Do not apply a 3-phase input FR inverter to 2-phase input applications. Otherwise, it will result in
faults or damage inverter.
1.2.10 Lightning Protection
FR200 has integrated lightning over-current protection device which has certain self-protection
capacity against the lightning. Additional protection devices have to be installed between inverter
and power supply in the area where lightning occurs frequently.
1.2.11 Altitude De-rating
In places where the altitude is above 1000 m and the cooling effect reduces due to thin air, it is
necessary to de-rate the AC drive. Contact FRECON for technical support.
1.2.12 some special usages
If wiring that is not described in this manual such as common DC bus is applied, contact the agent
or FRECON for technical support.
1.2.13 Cautions for Inverter Disposal
The electrolytic capacitors on the main circuit and PCBA may explode when they are burnt.
Emission of toxic gas may be generated when the plastic parts are burnt. Please dispose inverter as
industrial wastes.
1.2.14 Adaptable Motor
The standard adaptable motor is adaptable four-pole squirrel-cage asynchronous induction motor
or PMSM. For other types of motor, select a proper AC drive according to the rated motor current.
The cooling fan and rotor shaft of non-variable-frequency motor are coaxial, which results in
reduced cooling effect when the rotational speed declines. If variable speed is required, add a more
powerful fan or replace it with variable-frequency motor in applications where the motor overheats
easily.
