1.2 Cautions
1.2.1 Motor Insulation Test
Perform the insulation test when the motor is used for the first time, or when it is
reused after being stored for a long time, or in a regular check-up, in order to
prevent the poor insulation of motor windings from damaging the AC drive
during the insulation test. A 500-V mega-Ohm meter is recommended for the
test. The insulation resistance must not be less than 5MΩ.
1.2.2 Thermal Protection of Motor
If the selected AC drive does not match the rated capacity of the motor ,
especially when the rated power of the AC drive is higher than that of the motor,
adjust the parameters for motor protection in the AC drive or to install thermal
relay to protect the motor .
1.2.3 Running Below and Above Rated Frequency
The AC drive provides frequency output of 0 to 600.00Hz. When the users use
the frequency converter for a long time, please pay attention to the motor
cooling or use of variable frequency motor. If the AC drive is required to run at
over 50Hz, consider the capacity of the machine.
Safety and Cautions

6
1.2.4 Motor heat and noise
The output of the AC drive is pulse width modulation (PWM) wave with certain
harmonic frequencies, and therefore, the motor temperature, noise, and
vibration are slightly greater than those when the AC drive runs at power
frequency (50Hz).
1.2.5 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.
1.2.6 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 theAC drive may be damaged.
1.2.7 When External Voltage is Out of Rated Voltage Range
The AC drive must not be used outside the allowable voltage range specified in
this manual. Otherwise, the AC drive may be damaged . If required, use a
corresponding voltage step-up or step-down device.
Safety and Cautions

7
1.2.8 The Derating of the AC Drive
Different power grade frequency converter has its default carrier frequency,
when to run at a higher carrier.frequency, the AC Drive must to reduce the
amount when running.
1.2.9 Prohibition of Three-Phase Input Change into Two-Phase Input
Do not change the three-phase input of the AC drive into two-phase input.
Otherwise, a fault will result or the AC drive will be damaged.
1.2.10 Surge Suppressor
The AC drive has a built-in over-voltage, over-current device for suppressing the
surge voltage generated when the inductive loads around the AC drive are
switched on or off. If the inductive loads generate a very high surge voltage, use
a surge suppressor for the inductive load to prolong the service life of the AC
drive.
1.2.11 Ambient Temperature and De-rating
The normal use of the frequency converter ambient temperature is -10℃ ~40℃ .
Temperature exceeds 40℃ ,the equipment need to reduce the amount of use.
The ambient temperature of each increase is reduced by 1.5%,the maximum
use of the ambient temperature is 50℃ .
1.2.12 Altitude and De-rating
In places where the altitude is above 1000m and the cooling effect reduces due
to thin air, it is necessary to de-rate the AC drive. Contact our company for
technical support.
1.2.13 Disposal
The electrolytic capacitors, plastic parts and other devices may explode when
they are burnt. Poisonous gas is generated when they are burnt. Treat them as
ordinary industrial waste according to relevant national laws and regulations.
Safety and Cautions

8
1.2.14 Adaptable Motor
tThe standard adaptable motor is adaptable four-polo squirrel-cage AC
asynchronous induction motor or PMSM. For other types of motor, select a
proper AC drive according to the rated motor current.
tThe cooling fan and rotor shaft of general 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 runs at low frequency for a long time.
t The standard parameters of the adaptable motor have been configured
inside the AC drive. It is still necessary to perform motor auto-tuning or modify
the default values based on actual conditions. Otherwise, the running effect
and protection performance will be affected.
tThe AC drive may alarm or even be damaged when short-circuit exists on
cables or inside the motor. Therefore, perform insulation short-circuit test
when the motor and cables are newly installed or during routine maintenance.
During the test, make sure that the AC drive is disconnected from the tested
parts.

Precautions on the wiring:
1. DC bus have residual voltage after the AC drive is switched off. Ensure
voltage is less than 36V before touching the equipment Otherwise, you may get
electric shock.
2. Braking resistor connecting terminals:
3. The AC drive output terminals: U, V, W
4. Protective grounding terminal PE: Must be reliably connected to the main
grounding conductor. Grounding wire diameter should be greater than 10mm²
and the resistance must be less than 5Ω. Otherwise, it may cause electric
shock, mal-function or even damage to the AC drive.Do not connect the
grounding terminal to the neutral conductor of power supply.
The cable length of the braking
resistor shall be less than 5m. Otherwise, it may damage the AC drive.
: If the motor cable is too long, this
will damage the motor insulation or generate higher leakage current, causing
the AC drive to trip in overcurrent protection. If the motor cable is greater than
30m, need to reduce the carrier to decrease the leakage current; if it is greater
than 50 m long, an AC output reactor must be installed close to the AC drive.

You can return to Level II menu from Level III menu by pressing PRG or

Here is an example of changing the value of F03.03 to 15.00 Hz:
After you press ENTER , the system saves the parameter setting first,
and then goes back to Level II menu and shifts to the next function code.After
you press PRG , the system does not save the parameter setting, but directly
returns to Level II menu and remains at the current function code.

1. Such a function code is only readable, such as, AC drive model, actually

2. Such a function code cannot be modified in the running state and can only
be changed at stop.
