It is notadvisable to installan electromagnetic contactorin the sideof
output power supply, because theoperation of openand close tothe
contactor when themotor is runningmay cause damageto the inverter
arising from over-voltageproduced during thisprocess. But itis still
necessary to installa contactor ifone of thefollowing three pointsoccurs:
1.The system offrequency converting governorused to controlenergy-
saving usually worksat a ratedrotation speed. To run thegovernor
economically, thereis a mustto remove theinverter.
2.The inverter participatesin some importprocedure and cannotstop
operating for along period oftime. Torealize free shiftin various control
systems and improvethe reliability ofthese systems, thereis a mustto
install a contactor.
3.When an invertercontrols several motors,there is amust to installa
contactor.
Caution: DO NOToperate the contactorif there isoutput of theinverter.
1.5 Cautionsfor Operation
HAZARD
Do not operateelectrical equipment withwet hands.
An inverter storedfor a yearor longer shouldbe given
powerup test beforeuse so thatthe main circuitfilter capacitor
could be recovered.When the inverter is inthe state ofpowerup,
it is necessaryto raise thevoltage gradually tothe rated value
with a voltageregulator. Generally, the chargingtime should be
controlled within 1~2hours. Otherwise, thereis the dangerof
electric shock orexposure.

ON, nor putany foreign matter, i.e., rodor other matterinside the
inverter. Otherwise,it may resultin serious damageto the
equipment or deathto personnel.
Do not openthe front coverwhile the inverteris powered ON.
Otherwise, there isthe danger ofelectric shock.
Be careful toselect the RestartMode. Otherwise, thereis
the danger ofpersonnel death.
WARNING
If the inverterruns at afrequency higher than50Hz, DO confirm
it is withinthe speed rangeacceptable by yourmotor bearing and
mechanical device. Otherwise, there isthe danger ofdamage to the
motor.
It is notadvisory to runthe reduction box,gear and other
mechanism that needlubricating at lowspeed for along period.
Otherwise, it mayreduce the servicelife of theseequipment or
even damage theequipment.
A generalmotor should bederated before usedue to less
effective ofheat dissipation whenit runs ata low frequency. If itis
a constant torqueload, then aforced method ora special variable
frequency motor shouldbe used torelease heat.
DO cut off the powersupply of aninverter set asidefor a long
time to avoidforeign matter orother things enterin it whichmay
cause damage tothe inverter oreven lead tofire.
The output voltageof inverter isPWM impulse wave.DO NOT
install a capacitoror surgecurrent sink (i.e.,a varistor) inthe

3.3.2 Cautions forWiring
Hazard!
Wait atleast 10 minutesafter power OFFbefore opening the frontcover
of the inverter.
Verifythe charge indicatorlamp is OFFbefore proceeding thework,
and be surethat the voltagevalue of themain loop terminalP and DCis
less than 36VDC.
The internal wiringof the invertershould be operatedonly by
authorized qualified personnel.
WARNING!
Verifythe rated inputvoltage of theinverter is matched
with ACpower supply. Otherwise, thereis the possibilityof
damage to theinverter.
Install in orderand only operatewiring after finishing
main parts installation.Otherwise, there isan electric
shock or damageto the inverter.
Do not performover-voltage withstandto the inverter,
for this hadbeen done properlybefore EX-factory.
Be sure toinstall a non-fusecircuit breaker inthe input
power supply sideof the inverterto prevent expanding of
accident due toan inverter problem,which may cause
damage to thedistribution equipment orlead to fire.
Be sure toconnect the groundterminal and themotor
casing to theground wire whichmust be coppercore. The
diameter of thecopper core shouldconform to therelevant
national standard.The ground resistanceshould be less
than 10 .
FORBIDDEN!
DO NOT connectAC powersupply to theoutput terminals marked
"U", "V" and"W". Otherwise, therewill be damageto the inverter.
DO NOT connectcontrol terminals (exceptterminals marked
"TA","TB" and "TC")to AC220V power supply, which maycause
damage to theinverter.
When the open-ended output terminal of thecollector
connects to anyinductive load, i.e., the relaycoil, do inserta
diode at eachend of theload in parallel.
The control wirein the inverteror the controlcabinet should
be at least100mm away fromthe power cable.DO NOTput
them in thesame metallic channel. If thesignal wire andthe
power cable needto intersect, theyshould intersect atan angle
of 90 . The control wire mustadopt STP(shielded twisted pair
wire); the shielded layer mustconnect to theterminal GND;
and the powerwire is recommended to usemetallic shielded
cable
The unavoidable strongelectromagnetic interference ofthe
inverter may havebad influence onall the electricalequipment
and meters inthe same environment.Toreduce interference, the
output cable ofthe inverter canbe inserted inthe metal pipe
connecting to theground or inthe metallic shieldedcable, and
connect the metallicshielded layer tothe ground. Inaddition, a
magnetic loop puton the outputcable is alsoeffective to reduce
interference.
