1 Safety information and use notice points
In order to ensure the safety of your personal and equipment, before using the
inverter, please read this chapter of contents conscientiously.
1.1 Safety precautions
There are three kinds of safe relevant warnings in this service manual, they
are as follows:
This symbol explains items that need to be paid attention to when being
operated.
This symbol is briefed on some useful information.
This symbol briefs on: If does not operate on request, may cause death,
severely injured or serious property loss.
.
(1) Forbid to connect U, V, W output end to AC power supply, otherwise cause the
complete damage of the inverter.
(2) Don't make P- and P + short-circuited, otherwise cause the inverter to be
damaged.
(3) The inverter is forbidden to install on the flammables, otherwise have danger of
fire.
(4) Don't install it in the environment with explosive gas, otherwise have danger of
causing explosion.

1.2 Use range
(1) This inverter is only suitable for three phases AC asynchronous motor in general
industrial field.
(2) While applying inverter to such equipments that relate much to the life, great
property, safety devices etc., must handle cautiously, and consult with producer,
please.
(3) This inverter belongs to the control device of general industrial motor, if used in
dangerous equipment, must consider the security safeguard procedures when the
inverter breaks down.
1.3 Use notice points
(1) EDS800 series inverter is voltage-type inverter, so temperature, noise and
vibration slightly increasing compared to power source running when using,
belongs to normal phenomenon.
(2) If need to run for a long time with constant torque of low-speed, must select
motor of frequency conversion for use. Use general asynchronous AC motor
when running at a low speed, should control temperature of the motor or carry
on heat dissipation measure forcedly, so as not to burn the generator.
(3) Such mechanical device needing lubricating as the gearbox and gear wheel, etc.,
after running at a low speed for a long time, may be damaged as lubrication
result become poor, please take necessary measure in advance.
(4) When the motor running with frequency above specified, besides considering the
vibration, noise increase of the motor, must also confirm speed range of the
motor bearing and the mechanical device.
(5) For hoist and great inertia load, etc., the inverter would shut off frequently due to
over-current or over-voltage failure, in order to guarantee normal work, should
consider choosing proper brake package.
(1) It is prohibited that connect AC220V signal to control ends except TA, TB, TC,
otherwise have danger of damaging property.
(2) If the inverter is damaged or without all parts, please don't install and operate it,
otherwise have danger of fire or cause personnel to be injured.
(3) When installing, should choose a place where can endure the inverter, otherwise
have danger of injuring personnel or damaging property while falling down.

(6) Should switch on/off the inverter through terminal or other normal order
channels. It is prohibited that switch on/off the inverter frequently by using
strong electric switch such as magnetic control conductor, otherwise will cause
the equipment to be damaged.
(7) If need to install such switch as the magnetic control conductor, etc. between
inverter output and the motor, please guarantee the inverter is switched on/off
without output, otherwise may damage the inverter.
(8) The inverter may meet with mechanical resonance of the load within certain
range of frequency output, can set up jumping frequency to evade.
(9) Before using, should confirm the voltage of the power is within the working
voltage range allowed, otherwise should vary voltage or order special inverter.
(10) In the condition of altitude above 1000 meters, should use the inverter in lower
volume, reduce output current by 10% of specified current after each 1500
meters height increasing.
(11) Should make insulation check to the motor before using it for the first time or
after a long time placement. Please inspect with 500V voltage-type megohm
meter according to method shown as graph1-1 and insulation resistance should
not be smaller than 5 MΩ, otherwise inverter may be damaged.
(12) To forbid assembling capacitor for improving power factor or lightningproof
voltage-sensible resistance etc., otherwise will cause malfunction trip of the
inverter or damage of the parts, shown as graph 1-2.

3 Installation and wiring
3.1 Installation ambient
3.1.1 Demand for installation ambient
(1) Installed in drafty indoor place，ambient temperature within -10ºC~40ºC，need
external compulsory heat sink or reduce the volume if temperature exceeds40ºC.
(2) Avoid installing in place with direct sunlight, much dust, floating fibre and metal

(1)Before wiring, assure power supply is cut off completely for 10 minutes and all LED indicator ligh
extinguished.
(2)Before internal wiring, confirm that DC volt. Between main loop end P+ and P- fall down to below DC36V.
(3)Wiring can only be done by professional person trained and qualified.
(4)Before electrification, check if voltage grade of the inverter is in line with that of power supply volt.,
otherwise will cause personnel injured and device damaged.
!
(1)Assure power cuf off completely for above 10 minutes before wiring, otherwise have danger of
getting electric shock.
(2)Forbid connecting power wire to output U, V, W of the inverter.
(3)There is current leakage in the inverter and leak current of middle/high power inverter is bigger than 5mA,
for safety reason，inverter and motor must be earthed safely, commonly use 3.5mm² above copper wire as
ground wire and ground resistance smaller than 10Ω.
(4)Before shipment compression resistance test of the inverter is passed，so user should not conduct
compression resistance test again.
(5)Should not assemble electromagnetic contactor and absorbing capacitance or other absorbing device,
see Fig.3-3.
(6)To be convenient to over current protect of input side and power off maintenance inverter should be
connected to power supply through relay.
(7)Connecting wire for relay input and output loop(X1~X8, OC1~OC4, FWD, REV), should use above
0.75mm² glued wire or shielding wire，one shielding layer end hung in the air, the other connected to
grounding end PE or E, connecting wire shorter than 20m.

3.4 Main loop terminal wiring
Fig.3-4 main loop simple wiring
3.4.1 Connection between inverter and fitting parts
(1) Must assemble disjunction device such as isolation switch etc. between
powersource and the inverter to assure personal safety when repairing the inverter
and needing compulsory power off.
(2) Power supply loop must have breaker or
fuse with over current protection function to
avoid malfunction expanding caused by failure
of after device.
(3) AC input reactor
If high-order harmonics between inverter and
Power supply is biggish which can’t fulfil
system requirement, or need to improve input
side power factor, AC input reactor is needed.
(4) Magnetic control conductor only be applied
to power supply control and don’t apply
magnetic control conductor to controlling on/off
of the inverter.
(5) Input side EMI filter
Can use EMI filter to inhibit high-frequency
conduction disturbance and emission
disturbance from inverter power supply wire.
(6) Output side EMI filter
Can use EMI filter to inhibit emission disturbance
noise and wire leakage current from output side.
(7) AC output reactor
Advise assembling AC outputreactor to avoid
motor insulation damage, too large over current
and inverter frequent protection when connecting wire from inverter to motor
