DL100 Series Universal Low-Power Inverter
Precautions Ⅰ
Precautions
DL100 series universal low-power inverters are applicable to general industrial
single-phase and three-phase AC asynchronous motors. If this inverter is used for
equipment which is failed and may cause personal injury (e.g. nuclear control system,
aviation system, safety equipment and instruments), please take care and consult with the
manufacturer; if it is used for dangerous equipment, that equipment should be provided
with safety protecting measures to prevent accident expansion in the case of inverter
failure. The inverter is produced under strict quality assurance system. However, in order
to protect your personal safety and equipment and property safety, before using this
inverter, please read this chapter carefully and conduct transportation, installation,
operation, commissioning and inspection according to relevant requirements.
1．Precautions of unpacking inspection
When unpacking, please confirm if
(1) There is any damage during transportation and any components are
damaged or dropped.
(2) The model and specifications stated on the inverter nameplate is
consistent with your order. If there is any omission or damage, please
contact your supplier promptly.
Nameplate of the inverter
On the left side of the inverter body, there is a nameplate marked with the
model and rated parameters of the inverter.

2．Safety precautions
In this manual, the wordings of “Danger” and “Caution” are defined as below.
2.1 Installation
1. The inverter shall not be installed on combustibles.
2. The frequency inverter shall not be installed at places with direct sunlight.
3. The frequency inverter of this series shall not be installed in the environment
of explosive gases, for fear of the danger of explosion.
4. No foreign matter is allowed to be dropped into the frequency inverter, for
fear of causing fires or injury.
5. During installation, the frequency inverter shall be installed at the place able
to bear its weight; otherwise, it may fall down or damage properties.
Danger: Serious damage to the equipment or personal injuries may
be caused if operating without following requirements.
Caution: Moderate injuries or minor injuries of personnel and material
loss may be caused if operating without following requirements.
The inverter shall not be dismantled or modified without authorization.

DL100 Series Universal Low-Power Inverter
Precautions Ⅲ
2.2 Wiring
1. Wire diameter shall be selected according to applicable electric code, and
wiring shall be done by qualified technicians.
2. Wiring shall not be started unless the power supply of the inverter is
completely disconnected.
3. The grounding terminal of the inverter must be reliably grounded; otherwise,
there can be a danger of electric shock.
4. Before wiring, make sure the power supply has been disconnected for over 10minutes;
otherwise, there may be a danger of electric shock.
5. The electronic elements in the inverter is quite sensitive to static electricity,
hence no foreign articles shall be placed into the inverter or contact the main
board.
2.3 Maintenance
3．Precautions of use
In this manual, the wordings of “Tip” and “Attention” are defined as below:
1. The inverter shall be installed in the place with good ventilation.
2. The motor’s temperature can be a little higher than that of industrial frequency
power during operation of the inverter, which is abnormal.
3. With long-term operation at low speed, the operation life of motor can be
affected due to the poorer heat dissipation effect. In this case,special frequency
converter shall be selected or the motor’s load shall be decreased.
4. When the altitude is over 1000m, the inverter shall be derated. Increase of
altitude for every 1500 m shall be ground for derating by 10%.
Tip: To give some useful information.
Attention: To indicate any precautions during operation.
Wiring, inspection and other maintenance work shall not be
done until the power supply is disconnected for 10 minutes.
No alternating current power supply is allowed to be connected
onto the U, V, and W of the inverter.

DL100 Series Universal Low-Power Inverter
ⅣPrecautions
5. If the operating environment is beyond the allowed conditions of the inverter,
please consult the manufacturer.
4．Scrapping precautions
Following attentions shall be paid when the inverter and its components are
abandoned:
Explosion of the electrolytic capacitor: electrolytic capacitor in the frequency
converter may cause explosion while burning.
Waste gas from plastic burning: harmful and toxic gas may be produced during
combustion of plastic and rubber products of the converter.
Disposal: please dispose of inverters as industrial wastes.
The inverter’s output terminal shall not be connected to any
filter capacitor or other RC absorption equipment.

Chapter3 Inverter Wiring
3.1 Wiring precautions
(1) Make sure intermediate circuit breaker is connected between the
frequency inverter and power supply to avoid expanded accident
when the frequency inverter is faulty.
(2) In order to reduce electromagnetic interference, please connect surge
sorber on the coil of electromagnetic contactor, relay and etc. in the
surrounding circuit of the frequency inverter.
(3) Please use shielded wire of above 0.3mm² for the wiring of such
analog signals as frequency setting terminal AI and instrument loop
(AO), etc. The shielding layer shall be connected on the grounding
terminal E of the frequency inverter with wiring length less than
30m.
(4) The stranded wire or shielded wire of above 0.75mm² shall be
selected for the wiring of input and output loop (X1-X4) of relay; and
the shielded layer shall be connected to the common port CM of
control terminals, with wiring length less than 50 m.
(5) The control wire shall be separated from the power line of major
loop;it shall be at a distance of above 10cm for parallel wiring and
vertical for cross wiring.
(6) The connecting wire between the inverter and the motor shall be less than
30m; and when it is longer than 30m, the carrier frequency of the inverter
shall be appropriately reduced.
(7) All leading wires shall be fully fastened with terminals to ensure good
contact.
(8) The pressurization of all the leading wires shall be in compliance
with the voltage class of the frequency inverter.
Absorption capacitor or other RC absorbers shall not be
installed at U, V and W output end of the frequency
inverter, as shown in figure 3-1.

3.2 Wiring of peripheral elements
Power supply
The inverter shall be provided with power in accordance with specification
of input power supply designated by this operating manual
Air switch
1) When the frequency inverter is maintained or not in use for a long time,
2) the air switch will separate the frequency inverter from the power
supply;
3) When the input side of the frequency inverter has failures like short
circuit, the air switch can provide protection.
Contactor
It can conveniently control power-supply and power disconnection of the
inverter, and the power-on and power-off of the motor.
AC reactor
1) To promote power factor;
2) To reduce harmonic input of the inverter against the grid;
3) Weaken influenced caused by unbalanced voltage of three-phase power
supply.
Brake resistance
When the motor is at the dynamic braking status, it can avoid producing over
high pumping voltage in the DC loop.
