Please use a 500V voltage type megohmmeter for the test, and the insulation resistance is not
less than 5 megohms.
Negative torque load
For occasions such as lifting loads, negative torque often occurs, and the inverter often trips due
to over-current or over-voltage faults . Braking components with appropriate parameters should be
considered.
Leakage current protector RCD requirements
When the equipment is in operation, a large leakage current will flow through the protective
grounding conductor. Please install a B-type leakage protector RCD on one side of the power supply.
When selecting the RCD of the leakage protector, the transient and steady-state leakage current to
the ground that may occur during the start-up and operation of the equipment should be considered,
and a special RCD with measures to suppress high-order harmonics, or a general-purpose RCD with
a large residual current should be selected.
Earth leakage warning
The device will generate a large leakage current during operation. Before connecting to the
input power supply, please be sure to ground it reliably. The grounding of the equipment must
comply with the relevant IEC standards of local regulations.
1.3
Inverter related
It is forbidden to install capacitors or pressure-sensitive devices to improve power factor on the
output side
Since the output of the inverter is a PWM wave, it is strictly forbidden to install a capacitor for
improving the power factor or a piezoresistor for lightning protection on the output side to avoid
possible tripping of the inverter or damage to the device.
The output end is externally connected with switching devices such as contactors
If there are switching devices such as contactors installed between the inverter and the motor,
please make sure that the inverter has no output and perform on-off operations, otherwise the
inverter will be damaged.
Operating Voltage
It is strictly forbidden to use directly outside the voltage range specified by FC100P. If the power
supply voltage is not suitable, the corresponding voltage regulating device should be used to
transform the voltage to obtain a voltage that meets the product's use.
Capacitor energy storage
In the event that the AC power supply is cut off, the capacitors in the frequency converter will
remain charged for a period of time, and the voltage is enough to kill. If the inverter has been
powered on before, you must cut off the AC power supply for more than 10 minutes, and confirm that
the internal charging indicator light is off, and the voltage between the power terminals (+) and (-) is
lower than 36V before disassembling the machine. .
Normally, internal circuitry discharges the capacitor. However, under some abnormal conditions,
the capacitor may not be able to discharge. In this case, please consult our company or distributors.
Three-phase input changed to single-phase input
For three-phase input inverters, users are advised not to change to single-phase input.
If single-phase power must be used, the input phase loss protection function should be
cancelled. The bus voltage and current ripple will increase, resulting in poor performance of the
inverter and shortened capacitor life; in this application, derating is required, not exceeding 60% of
the rated value of the inverter.
