Provided problems occur and solution is not provided in this instruction manual, contact your SANCH
ELECTRIC representative or contact with our company directly. Our professional technicians will serve
for you actively.And please continue to adopt products of SANCH, give valuable opinion and advice.
1. Reading Instructions
symbols of” DANGER” and” ATTENTION” in the manual indicates that, for safety running or
maintenance of inverters or other electrical products, attention shall be attached during delivering,
installation, operation and checks for the inverter. And these notes shall be applied for a better and safer
operation.
DANGER
indicates a potentially hazardous situation visiting. If not used correctly, personnel
damage even death may be caused.
CAUTION
indicates a potentially hazardous situation visiting. If not used correctly, serious
damage to inverter or machine may be resulted.
ATTENTION

Do not perform a withstand voltage test for components of inverter, it can cause
semi-conductor components to be damaged by high voltage.
Never connect the output terminals U/T1, V/T2, W/T3 to AC power supply.

IC of CMOS on control circuit of the inverter shall be damaged by electrostatic
influence. Do not touch main circuit board.
2. Products receiving
All products have been performed with strict test and inspection. After receiving the inverters, the
following checks shall be performed.
To check that SANCH inverter, an instruction manual.
To check whether model number correspond with model and capacity your purchase order.
To check whether there are damaged parts during transportation and delievering. If there are,
do not connect with power supply.
If any of the above checkpoints are not satisfactory, contact your SANCH ELECTRIC representative
for a quick resolution.
DANGER

Do not touch circuit board and other components after power supply off and
CHARGE indicators are still ON.

Never connect wires while power on. Do not check components or signal for
circuit board during operation.
Do not
dismantle or change inner wire, circuit or components unnecessarily.

1 SAFETY INSTRUCTIONS
1.1 NOTES FOR OPERATION
Before wiring
●Specification of app
lying power supply shall correspond to input voltage of the
inverter.
DANGER
●Main circuit terminals must be correct, L1/R, L2/ S and L3/ T is input terminals and it’s
forbidden to use mixing with U/T1, V/T2 and W/T3. Failure to observe this may cause
the inverter damaged.
CAUTION
●
When delivering the inverter, do not take the cover directly. Take the air fan seat to
prevent the cover got off. Inverters getting off which may cause damage to personal
or machine shall be avoided.
●Install the inverter on metal or other non-
inflammable materials. Do not fix it on
inflammable materials which may cause a fire hazard.
●
In case of several inverters are installed together in one control panel, a fan shall be
prepared to make sure temperature lower than 50℃, thus over-
heating or a fire
hazard shall be avoided.
●
Make sure applied power supply comply with label showed on the right of the
machine. Failure to observe this may cause action failure.
During operation DANGER
Never put in or take off the motor during operation, otherwise over-current even over
burning the main circuit of the inverter may happen.
When auto-restart function is set, do not approach the machine since motor can be
reset suddenly after being stopped.
The function set can make the stop key invalid, which is different from the emergency
stop key. Please pay attention to it.

CAUTION
●Never touch heatsink or discharging resistor since temperature may be very high.
●Since it is easy to change running speed from low to a high speed, verify safe working
range of motor and machine before running.
●Use brake according to the method described in wiring diagram.
●Do not check signals during running.
●
All parameters of the inverter have been preset at the factory according to line
frequency. Do not change the setting value at will.
During check and maintenance CAUTION
●Ambient temperature for operating the inverter shall be -10℃to + 50℃(+40℃
parallel installation) and 90%RH no condensation. However under this condition, the
ambient environment must be without drips of water or metal dust.
During rejection CAUTION
●Explosion may occur when burning the electrolytic capacitor of the main circuit and
printing plate. Toxic gas may be generated when burning control panel and other
plastic fittings. It shall be treated as Industrial waste.

between AC supply and inverter.
No fuse Breaker
No fuse Breaker:

Circuit breaker which complies with rated voltage and

shall be applied.
Do not use the magnetic contactor as RUN/STOP switch
for inverter.
Input side Noise Filter
Power ImprovingAC Electric Reactor

When the output capacity is greater than 500KVA or
enter-
wire electricity capacity acts, the instant jump of
voltage or current will be produced, resulting to damage
the internal circuit. So it is recommended that an AC
electric reactor is installed additionally to improve function
factors and decrease the power harmonic. The wiring
distance is within 10m.

Note: In the following several states, indicator lights are combined to indicate the inverter state.
set the inverter to operate, RUN indicator light is on and STOP flickers when the output
frequency is 0.
set the inverter to stop, RUN indicator light flickers and STOP is on when the output
frequency hasn’t decreased to 0.
If it is necessary to set the inverter to do the reverse operation when it is in forward operation
state, stop the forward operation first, then start the reverse operation. The FWD indicator
light flickers and REV is on before the forward rotating stops.
If it is necessary to set the inverter to do the forward operation when it is in reverse operation
state, stop the reverse operation first, then start the forward operation. The FWD indicator
light is on and REV flickers before the reverse rotating stops.
