water, or component is missing or broken;
Do not install the product if the label on the
package is not identical to that on the inverter.
Caution
Be careful of carrying or transportation. Risk of
devices damage.
Do not use damaged product or the inverters
missing component. Risk of injury.
Do not touch the parts of control system with
bare hands. Risk of ESD hazard.
Installation
Danger
Installation base shall be metal or other
non-flammable material. Risk of fire.
Do not install inverter in an environment
containing explosive gases, otherwise there is
danger of explosion.
Do not unscrew the fixing bolts, especially the
bolts with red mark.
Caution
Do not leave cable strips or screws in the
inverter. Risk of inverter damage.
Install the product at the place with less vibration
and no direct sunlight.
Consider the installation space for cooling
purpose when two or more inverters are placed
in the same cabinet.

The use phase
Safety class
Precaution
Wiring
Danger
Wiring must be performed by authorized and
qualified personnel. Risk of danger.
Circuit-breaker should be installed between
inverter and the mains. Risk of fire.
Make sure the input power supply has been
completely disconnected before wiring. Failure to
comply may result in personnel injury and/or
equipment damage.
Since overall leakage current of this equipment
may be bigger than 3.5mA, for safety's sake, this
equipment and its associated motor must be well
grounded so as to avoid risk of electric shock.
Never connect the power cables to the output
terminals (U, V, W) of the AC drive. Pay attention
to the marks of the wiring terminals and ensure
correct wiring. Failure to comply will result in
damage to theAC drive.
Install braking resistors at terminals (P+) and (P-
or PB) only. Failure to comply may result in
equipment damage.
Caution
Since all adjustable frequency AC drives from our
company has been subjected to hi-pot test before
delivery, users are prohibited from implementing
such a test on this equipment. Failure to comply
may result in equipment damage.
Signal wires should to the best of the possibility
be away from main power lines. If this cannot be
ensured, vertical cross-arrangement shall be
implemented, otherwise interference noise to
control signal may occur.
If motor cables are longer than 100m, it is

7
The use phase
Safety class
Precaution
recommended outputAC reactor be used.
Failure to comply may result in faults.
Before
Power-on
Danger
Inverter shall be power-on only after the front
cover is assembled. Risk of electrical hazard.
Caution
Verify that the input voltage is identical to the
rated voltage of product, correct wiring of input
terminals R, S, T and output terminals U, V, and
W, wiring of inverter and its peripheral circuits,
and all wires should be in good connection. Risk
of inverter damage.
After Power-on
Danger
Do not open the cover after power. Rick of
electrical hazard.
Do not touches any input/output terminals of
inverter with bare hands. Rick of electrical
hazard.
Caution
If auto tuning is required, be careful of personal
injury when motor is running. Risk of accident.
Do not change the defaults of parameters. Risk
of devices damage.
During
Operation
Danger
Non-professionals shall not detect signals during
operation. Risk of personal injury or device
damage.
Do not touch the fan or the discharging resistor to
check the temperature. Failure to comply will
result in personal burnt.
Caution
Prevent any foreign items from being left in the
devices during operation. Risk of device damage.
Do not control start/stop of inverter by ON/OFF of
contactor. Risk of device damage.

The use phase
Safety class
Precaution
Maintenance
Danger
Maintenance and inspection can only be
performed by professionals. Risk of personal
injury.
Maintain and inspect devices after power is off.
Risk of electric hazard.
Repair or maintain the AC drive only ten minutes
after theAC drive is powered off. This allows for
the residual voltage in the capacitor to discharge
to a safe value. Failure to comply will result in
personal injury.
All pluggable components can be inserted or
pulled out only when power has been turned off.
Set and check the parameters again after theAC
drive is replaced.
1.2 Precautions for use
When using the DGI900 series inverter, please pay attention to the following points：
1.2.1 Constant torque and low speed operation
When the inverter is running with a normal motor for a long period of low speed, the heat
dissipation effect will be deteriorated, which will affect the life of the motor. If you need
low-speed constant torque for long-term operation, you must use a dedicated inverter
motor.000000000000000000000000000
1.2.2 Confirmation of motor insulation
When applying the DGI900 series inverter, please confirm the insulation of the motor before
using the motor to prevent damage to the equipment. In addition, please check the insulation
of the motor regularly when the environment of the motor is bad, to ensure the safe operation
of the system.
1.2.3 Negative torque load
For situations such as lifting the load, there is often a negative torque, and the inverter will
trip if an overcurrent or overvoltage fault occurs. In this case, the optional braking resistor

9
should be considered.
1.2.4 Mechanical resonance point of the load device
The inverter may encounter the mechanical resonance point of the load device within a
certain range of output frequency, and must be avoided by setting the jump frequency.
1.2.5 Capacitance or varistor for improving power factor
Since the output voltage of the inverter is pulse wave type, if the output side is equipped with
a capacitor with improved power factor or a varistor for lightning protection, it will cause the
inverter to trip or damage the device. Be sure to remove it, and it is recommended not to be
on the output side. Add switching devices such as air switches and contactors, as shown in
Figure 1-1. (If the output of the inverter must be zero when the output side switch device is
activated)
Figure 1-1 Disabling the capacitor at the output of the inverter
1.2.6 Derate at Basic frequency setting
When the fundamental frequency setting is lower than the rated frequency, please pay
attention to the derating of the motor to avoid overheating of the motor.
1.2.7 Operating at frequencies above 50Hz
If it is operated above 50 Hz, in addition to considering the vibration and noise of the motor, it
is necessary to ensure the speed range of the motor bearings and mechanical devices.
1.2.8 Electronic thermal protection value of the motor
When the adapter motor is selected, the inverter can thermally protect the motor. If the motor
does not match the rated capacity of the inverter, be sure to adjust the protection value or
take other protective measures to ensure the safe operation of the motor.

10
1.2.9 Altitude and derating
In areas where the altitude is more than 1000 meters, the heat dissipation effect of the
inverter is deteriorated due to the thin air, and it is necessary to derate the use. Figure 1-2
shows the relationship between the rated current of the inverter and the altitude.
Figure 1-2 Inverter rated output current and altitude derating diagram
1.2.10 About the degree of protection
The protection level IP20 of the DGI900 inverter refers to the degree of protection achieved
when the status display unit or keyboard is selected.
1.3 Disposal considerations
When scrapping the inverter, please note:
The electrolytic capacitor of the main circuit and the electrolytic capacitor on the printed
circuit board may explode when incinerated. Poisonous gas is generated when plastic parts
are incinerated body. Please treat as industrial waste.
