Chapter 1 Safety Precautions
Unpackage Inspection
Upon unpacking, check:
• Whether the nameplate model and AC drive ratings are consistent with your order. The box
contains the AC drive, certificate of conformity, user manual and warranty card.
• Whether the AC drive is damaged during transportation. If you find any omission or
damage, contact your supplier immediately.

1.2 Safety Information
The use phase Safety class Precaution
Before
Installation Danger
Do not install the product if the package is with ◆
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.
Fig 1 1. Models description

7
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.

8
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 the AC drive.
Install braking resistors at terminals (P+)and ◆
(P or PB) only. Failure to comply may result in
equipment damage.

9
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 ◆
recommended output AC 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.

10
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.
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 the AC drive is powered off.
This allows for the residual voltage in the

11
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 the AC drive is replaced.
General Precautions
1. Constant torque low frequency running
When inverter with induce motor running at long time low speed, the effection of heat
emission will get worse and influence motor using life. If low speed constant torque running
for long time, user have to use Variable frequency motor.
2. Motor insulation test
Perform the insulation test when the motor is used for the first time, or when it is re used
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. The motor must be disconnected
from the AC drive during the insulation test.
3. Hoist load
In Hoist load application, as the inertia exist, inverter will trip as over current or overvoltage
fault. In the case, braking unit and resistor should be connected.
4. Vibration of mechanical device

12
The AC drive may encounter the mechanical resonance point at some output frequency,
which can be avoided by setting the skip frequency.
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.

6. Derate at Basic frequency setting
When basic frequency is lower than rated frequency, be caution to derate motor avoilding
motor burn.
7. Running at over 50 Hz
If the AC drive is required to run at over 50 Hz, motor viberation and noise will increase.
Consider the capacity of the machine.
8. Thermal protection of motor
AC DRIVE
Fig 1 2. Inverter not allowed to connect capacitor

13
If the rated capacity of the motor selected does not match that of the AC drive,
especially when the AC drive's rated power is greater than the motor's, adjust the motor
protection parameters on the operation panel of the AC drive or install a thermal relay in the
motor circuit for protection.
9. Altitude and 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.
10. Protection class
DGI900 protection level is IP20 when inverter with keypad.
Fig 1 3. Inverter output current derating and Altitude

14
Disposal
The electrolytic capacitors on the main circuits and PCB may explode when they are burnt.
Poisonous gas is generated when the plastic parts are burnt. Treat them as ordinary
industrial waste.
