PRECAUTION
Never modify the products. Failure to observe this warning
can result in electrical shock or personal injury. SAJ is not
responsible for any modification of the frequency products
made by the user, since that will void your guarantee.

Notes for Safe Operation
Read this instruction manual thoroughly before installation, operation,
maintenance or inspection of the frequency inverters. In this manual, safe
operation are classied as “WARNING” or “CAUTION”.
WARNING
Indicate a potentially dangerous situation which, if not avoided, could result
in death or serious injury to personnel.
CAUTION
Indicate a potentially dangerous situation which, if not avoided, could result
in minor or moderate injury and damage to equipment. It may also be used
for warning against unsafe practices.
Even items described as ( CAUTION) may result in a vital accident in some
situations. Please follow these important notes:
NOTE
These are steps to be taken to ensure proper operation.
Before Installation
WARNING
Do not install or operate any frequency inverter that is damaged or has
missing parts.
Choose the motor of insulation class B or above. Otherwise it may cause
an electrical shock.

-02-
8000B Series
Installation
WARNING
Install the frequency inverter on nonflammable material like metal.
Otherwise it may cause a fire.
WARNING
Make sure that the mounting environment away from metal dust. Otherwise
it may cause damage to the frequency inverter.
CAUTION
When mount over two inverters in the same cabinet or enclosure, install a
fan or other cooling device to keep the temperature inside below 50℃.
Do not let the conductor head or screws fall into the inside of the inverter.
Otherwise it may cause damage to the inverter.
Wiring
WARNING
Ensure only qualified personnel to operate. Otherwise it can cause an
electrical shock.
Make sure the inverter is isolated from power supply by the circuit breaker.
Otherwise it may cause a fire.
Verify that the power supply is turned OFF before start wiring. Otherwise it
may cause an electrical shock or fire.
Make sure that the ground terminal is grounded correctly. Otherwise it may
cause an electrical shock.

-03-
8000B Series
CAUTION
Never connect the AC power supply to output terminals U, V and W.
Otherwise the inverter will be damaged and the guarantee is invalid.
Make sure that wiring conform to EMC requirements and local power safe
standard. Make sure to use right wire according to this instruction manual.
Otherwise it may cause an accident.
Braking resistor or braking unit cannot be directly connected to DC bus
terminals (P+) and (N-). Otherwise it may cause a fire.
Before Turn on the AC Power Supply
WARNING
Make sure that the voltage of inverter conforms to the local power supply
voltage. Verify that the wiring of input and output is correct and there is no
short-circuit in peripheral circuit. Tighten the terminal screws. Otherwise
these may cause damage to the inverter.
Turn on the input AC power only after the front cover is put correctly.
Otherwise it may cause an electrical shock.
CAUTION
Never perform a hi-pot or withstand voltage test of the inverter. Otherwise
it may cause damage to the inverter.
Make sure that the optional parts are connected correctly. Otherwise it
may cause damage to the inverter.

-04-
8000B Series
When the Power is On
WARNING
Do not open or remove the front cover when operation. Otherwise it may
cause an electrical shock.
Never touch the inverter and optional parts by wet hands. Never touch the
connection terminals. Otherwise it may cause an electrical shock.
When the power is on, the inverter will automatically check the power
supply circuit. Do not touch U, V, W terminals and motor connection
terminals. Otherwise it may cause an electrical shock.
CAUTION
It is dangerous for the personnel to approach the motor and load during
rotation of the motor. Do not change the factory parameters or settings
unnecessarily. Otherwise it may cause a damage or injury.
Operation
WARNING
When select the function of restart, do not approach the mechanical load.
Otherwise it may cause an injury if it restarts suddenly.
Do not touch the heat sink or discharging resistor. Otherwise it may cause
harmful burns to the body.
Never change or check signals if not a professional or qualified personnel.
Otherwise it may cause damage and injury.
CAUTION
Make sure nothing fall into the mechanical load or inverter. Otherwise it
may cause damage.
Start or stop inverter by corresponding buttons only. Otherwise it may
cause damage.

-05-
8000B Series
Maintenance
WARNING
After the main circuit power supply is OFF, make sure the charge LED
is OFF when maintain or inspect. Never maintain or inspect the inverter
and mechanical load when the power supply is still ON. Otherwise it may
cause damage and injury.
Only qualified or authorized professional personnel can maintain, replace
and inspect the inverter. Otherwise it may cause damage and injury.

8000B Series
Notes for Other Important Operations
CAUTION
1. Check Insulation of the Motor
Check insulation of the motor and wire when the motor is used again after
long time idle or for the rst time. Disconnect the wire between the motor and
the inverter before check insulation. Make sure the insulation resistor is not
below 5MΩ.
2. Thermal Overload Protection of the Motor
When the rated capacity of inverter is larger than that of the motor, install
thermal overload relay for the motor or regulate the motor protection
parameters of the inverter.
3. Consider the Bearing Capability of the Load
The inverter can provide output frequency from 0 Hz to 600 Hz. If the motor
needs to work at over 50 Hz, user should consider the bearing capability of
the load.
4. Avoid Mechanical Resonance Frequency
Regulate the skip frequency parameter of the inverter to avoid mechanical
resonance frequency of the load.
5. Prohibition of Installation of Phase Advancing Capacitor
If a phase advancing capacitor or surge suppressor is connected in order to
improve the power factor, it may become overheated and damaged by inverter
high harmonic components. Also, the inverter may malfunction because of
over current.
6. Installation of Magnetic Contactor
If a magnetic contactor is installed at the power supply side, do not use it to
control the start of the inverter. If necessary, the time span should be one hour
or above. Otherwise frequent switching may cause the inverter to malfunction.
If a magnetic contactor is installed between the output terminals and motor
(output side of the inverter), make sure there is no output of inverter before
switch on and off. Otherwise it may cause damage to the inverter.

-07-
8000B Series
7. Allowable Voltage Range and Power Supply Phase
Make sure the inverter works under allowable voltage range. If necessary, use
boosting transformer or step-down transformer to change the voltage of power
supply. Never change the 3-phase of inverter into 2-phase. Otherwise it will
cause damage to the inverter.
8. Thunder Stroke Protection
Even there is protection device to protect the inverter from induction thunder
stroke, it’s necessary for users in frequent thunder stroke area to install other
protective device.
9. Altitude and Degradation Use
At an altitude of 1000m or above, it could be better that use the motor with
lower rated capacity. Otherwise the inverter may become overheated because
of rare air. For example, in order to control the motor of 4kW rated capacity, it
could be better to use 5.5kW inverter.
10. Dispose of Scrap Inverter
The scrap capacitor of main circuit and PCB (printed-circuit board) may
explode when it is burned. In order to protect the environment, do not burn
waste plastic parts and scrap capacitor.
11. Choose the Right Matching Inverter for the Motor
The standard matching motor is 4-pole inductive motor. If not, choose the right
matching inverter according to the rated current of the motor.
According to the actual working situation of the motor, the factory setting
of motor standard parameter can be revised. Otherwise it may cause low
efciency to the unit.
