Preface
This instruction manual, which includes operation descriptions and notes for maintenance, shall be
delivered to the end-user.
For safety running and effective operation, this instruction manual shall be read thoroughly prior to use,
which shall also be preserved for later use. 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, V, W to AC power supply.
IC of C
MOS 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 and a cover is inside of the package
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
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.
Make sure grounding terminals are correctly grounded. 220V level: Grounding
Ⅲ; 200V level: Special Grounding

CAUTION
1 SAFETY INSTRUCTIONS
1.1 NOTES FOR OPERATION
Before wiring
Specification of applying power supply shall correspond to input voltage of the inverter.
DANGER
Main circuit terminals must be correct, R/L1, S/L2 and T/L3 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 40℃, thus over -
heating or a fire
hazard shall be avoided.
●
Operator shall be dismantled or refitted after power supply is off. Fixed operator shall
be processed as diagram shows to prevent operator fault or no display.
●Make sure applied p
ower 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.
●Do not remove the cover while current is flowing. Failure to observe this may result in
electrical shock to personnel.
●When auto-restart function is set, do not approach the machine since motor can be
reset suddenly after being stopped.
●
Since STOP button can be selected by function set, which is different from usage of
emergency stop/on switch, attention shall be given to the usage.

3
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.
●Pay attention to relative settings before using the brake.
●Do not check signals during running.
●All parameters of the invert
er have been preset at the factory according to line
frequency. Do not change the settings unnecessarily.
●
Do not perform dismantling or checks while power supply and charging indicator”
CHARGE” are still on.
During check and maintenance CAUTION
●Ambient temperature for operating the inverter shall be -10℃to + 40℃and 90%RH
non moistring condensation.
●After removing the dust-cover, ambient temperature for operating the inverter shall be
-10℃to + 50℃
and 95%RH non moistring condensation. However under this
condition, the ambient environment must be without drips of water or metal dust. If
there are, the dust cover shall be refitted and check whether ambient temperature is
within -10℃to + 40℃simultaneously.
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.

1.2 NOTES FOR OPERATION ENVIRONMENT
Make sure the inverter is protected from the following during operation:
Direct Sunlight.
Corrosive gas
or
fluids Oil l
Salt or saline Rain, moisture Iron chips and dust
Large impelling
Extreme low
temperatures
Extreme high ambient
temperatures (Above 40℃)
Electromagnetic waves and
ultra high-
angle rays (For
example: locations of
welding machines and etc.)
Radioactive materials
Locations of inflammable
materials

2 DESCRIPTIONS FOR SANCH AND INSTALLATION
2.1 OPERATION ENVIRONMENT
Since operation environment can directly influence functions and operation life, to ensure proper
performance and long operation, follow the recommendations below when choosing allocation for
installing the inverter. Make sure it is protected from the following:
Extreme cold and heat.
Use only with the ambient temperature range: -10℃to + 40℃; -10℃to + 50℃applicable when dust
cover is removed.
Rain, moisture
Direct sunlight.(Avoid using outdoors)
Corrosion of oil sprays or salt
Corrosive fluid and methane
Dust or metallic particles in the air.
Radioactive materials and inflammable materials
Electromagnetic interference (Avoid using together with welding machine or dynamic machines.)
Vibration.
(If inverter must be used in this environment, an anti vibration pad is necessary).
Attention shall be attached to clearance of inverters allocated closely. A fan shall be installed to
make sure temperature is lower than 40℃
correct configuration
For cooling off, face shall be toward front and upper parts shall be upwards.
Clearance shall meet the following specifications: (If the inverter is installed inside the cabinet or
environment is allowable, dust cover shall be available to be removed for ventilating.)
