1 Safety information and use notice points
To make ensure personal & equipment safety, this chapter must be read carefully
before the inverter come into use.
1.1 Safety precautions
There are three kinds of safety warnings in this manual as below:
Symbol Symbol description
It may cause human death, serious injury or heavy property loss
with wrong operation.
It may result body or device damage with wrong and timeless
precautions under operation.
Should pay extra cautions when inverter in use under this
symbol
!
Note
!

1 Safety information and use notice points
2
Forbid to cut off the power source directly when inverter under
running, acceleration or deceleration status. Power source could
cut off when inverter completely in halt and standby status.
Otherwise user should be responsible for inverter and device
dama
g
e and human in
j
ur
y
.
!
(1) Forbid to connect AC power source to output terminal U,V,W,
otherwise it could cause inverter completely damage.
(2) Not allow for short circuit between(-)and(+)，otherwise it could
cause inverter damage and power source short circuit.
(3) Forbid to install inverter on flammable objects, otherwise it
may cause fire.
(4) Do not install inverter in a environment with explosive gas, it
may cause explosion.
(5) Bare connection terminal should be insulation treatment after
main loop connection, otherwise it may cause electric shock.
(6) Do not operate inverter with wet hands when inverter power
on, otherwise it may cause electric shock.
(7) Inverter earth terminal should be well grounding connection.
(8) Do not open the front cover for wiring when inverter power on.
Inverter wiring and check must handle after 10 minutes of
inverter power off.
(9) Wiring connection should handle by qualified person and not
allow to slip any conductive objects inside inverter, otherwise it
may cause a electric shock or inverter damage.
(10) when inverter stocked for more than 6 months, using voltage
regulator to boost voltage up and keep inverter in standy status
for 1 hour, otherwise it may cause electric shock and explosion.
!
(1) Forbid to connect control terminals except TA, TB, TC to AC
220V/380V signal, otherwise it may cause inverter completely
damage.
(2) Do not install and run inverter when inverter damage or spare
part less, otherwise it may cause fire or human injury.
(3) inverter should install in a place where can accept itself weight,
otherwise it may cause inverter drop down or belongings damage.

1.2 Application range
(1) This kind of inverter apply to 3 phase ac asynchronous motor only for general
industry.
(2) It should handle cautiously and consult with manufacturer when inverter apply
to high reliability required equipment which relevant to life, properties and safety
device.
(3) This kind of inverter is the general motor control device in industry. When
inverter apply to dangerous equipment, safeguard should be considerable in case
of inverter failure.
1.3 Use notice points
(1) DGI500/DGI600 series inverter belong to voltage type inverter, and it is
normal with up temperature, noise and vibration of motor increasing over power
frequency run slightly.
(2) It is required to match inverter with variable frequency motor running at low
speed with constant torque for long time. When match inverter with general
asynchronous motor running at low speed, it should take measures to make motor
heat dissipation or monitoring motor temperature in avoid of motor flash.
(3) It is necessary to take measures in advance for the damage caused for the bad
lubrication of the reduction box and wheel gear mechanical devices running at
low speed for long time.
(4) It is necessary to assure at first that the use speed range of motor bearings and
mechanical devices, also the increasing of motor vibration and noise should be
considered, when motor run over rated frequency.
(5) It is necessary to select the suitable brake assembly for hoisting device and big
inertia load to make sure the normal work when inverter stripping from power
grid for the overcurrent or overvoltage failure.
(6) Inverter start and stop control through terminal or other normal command
channel, otherwise it may cause inverter damage via connecting inverter input
terminal to big current switch just like contactor direct to start and stop inverter
frequently.
(7) It is necessary to make sure inverter cut off from operation without output,
when inverter and motor connect through switch components just like contactor
etc. Otherwise it will cause inverter damage.
(8) When inverter output frequency within some range, it may meet mechanical
resonance point of load device, through setting jump frequency to avoid it.
(9) Checking power supply voltage within allowed working range before usage,
otherwise, it need to change voltage or custom special voltage inverter.

1 Safety information and use notice points

(10)When inverter usage site altitude over1000 meters，inverter should derate
current to use, output current decrease about 10% of rated current per 1000 meters
increase.
(11)Motor should do insulation check before first usage or reusage after lay aside
for long time. Checking method show as graph 1-1 below with 500V voltage type
megohm meter , insulation resistance should not smaller than 5 MΩ，otherwise
inverter maybe damaged.
(12)Forbid inverter output side to assemble capacitor to improve power factor or
anti-thunder dependent resistor etc, otherwise it may cause inverter fault trip or
component damage show as graph 1-2.
Fig.1-1 motor insulation check Fig.1-2 capacitor at output side forbidden
1.4 Scraping handling notice:
Notices when handling with scrapped inverter and components:
(1) The unit: dispose the inverter as industrial waste.
(2) Electrolytic capacitor: It may cause explosion when electrolytic capacitor
under burning.
(3)Plastic: it may result in harmful and poisonous gas when plastic and rubber of
inverter burning, and safeguard preparations should be taken before burning.

1. EN-LCD2 long-distance keypad outer lead, do not support
keypad holder installed, only keypad installed support, mounting
size refer to Fig.2-7.
2. Except EN-LCD2 long-distance keypad, when other keypad
outer lead, user can adjust the hole size under actual situation on
keypad or keypad holder; thickness of install board between 1.0～
1.5mm is suggested.
3. When installed with keypad holder, it need to buy extra.
