Chapter 1 Safety points and precautions Chapter 1 Safety points and precautions
1.2 Precautions
1.2.1 Examination for motor insulation
The motor should be given the insulation examination when it is used at first time
and reused after long-time no service and when it is checked regularly, to prevent
the inverter being damaged for poor insulation of motor windings. When conducting
the check for insulation, must separate the motor wires from the inverter. It is
suggested that 500V megohmmeter should be used to measure, the measured
insulation resistance should not be less than 5M.
1.2.2 Thermal protection for motor
When the rated capacity of motor doesn't match with that of inverter, especially,
the rated power of inverter is larger than that of motor, please adjust the related
motor-protection parameters inside the inverter or mount a thermal relay in front of
motor additionally to protect the motor.
1.2.3 Running at above power frequency
The inverter can provide the output frequency of 0～600Hz. If user wants it to
run at 50Hz above, please take the bearing capacity of mechanical device into the
consideration.
1.2.4 Vibration of mechanical device
The inverter may meet the mechanical resonant points of load device at some
power frequencies, which can be avoided through setting the hopping frequency
parameters inside the inverter.
1.2.5 Motor heat and noise
Because the inverter output voltage is PWM wave, including the certain harmonic,
the temperature rise, noise and vibration of motor will be increased slightly
compared with that when the inverter runs at power frequency.
1.2.6 Varistor or capacitor for improving the power factor on the output side
Because the inverter outputs PWM wave, if the capacitor for improving the power
factor or lightning-protection varistor is mounted on the output side, the
instantaneous over current is easily produced to damage the inverter, please don't
install them.
1.2.7 Contactors mounted at input and output terminals
If the contactor is mounted between the power supply and inverter input terminal
additionally, it is not allowed to control the start and stop of inverter. If necessary,
the interval of control should not be less than 1hour, because the frequent charge
and discharge will easily reduce the service life of capacitor that is in the inverter. If
the contactor is mounted between the output terminal and motor, please make sure
that the inverter performs the making and breaking operation when it has no output,
otherwise the inverter module will be damaged easily.
1.2.8 Use beyond the rated value
SY8000 series inverter should not be used beyond the permissible working
voltage specified in this manual, otherwise, the inverter parts will be damaged. If
necessary, please use the step-up or stepdown device for transformation treatment.
1.2.9 Changing three-phase input into two-phase input
SY8000 series three-phase inverter is not allowed to be used as two-phase one,
otherwise, the fault or damage of inverter will happen.
1.2.10 Lighting impact protection
The inverter has the lightning over current protection device, so, it has a certain
self-protection ability to resist the induction lightning. For the lighting frequent
occurrence area, a protection device should be mounted in front of inverter.
1.2.11 Altitude and derating use
In the area where the altitude exceeds 1,000m, the heat emission efficiency of
inverter gets bad for the tenuous air, therefore, it is necessary to reduce the
capacity. Please contact us for technology enquiry for this case.
1.2.12 Some special methods
If user needs the connection methods that are not specified in this manual, such
as the common DC bus, please contact us.
1.2.13 Attentions against the rejection of inverter
The electrolytic capacitor at main circuit and the one at the printed board may be
exploded when they are burned. The plastic part may produce the poisonous gas
when it is burned, therefore, they shall be treated as the industrial rubbish.
1.2.14 Applicable motor
1.2.14.1 The standard applicable motor is the four-pole squirrel cage
asynchronous induction motor. If your motor is not the abovementioned one, please
select the inverter according to the rated current of motor. If needing the drive of
permanent magnet synchronous motor, please contact us.
1.2.14.2 The cooling fan of non-frequency conversion motor is connected
coaxially with the rotator, the cooling efficiency of fan is lowered with the rotation
speed, therefore, a strong exhaust fan or frequency-conversion fan is mounted
against too much heat.
1.2.14.3 The inverter has provided the standard parameters of built-in motor,
according to the actual situations, please perform the motor parameter
identification or amend the default to accord with the actual value, otherwise, the
running efficiency and protection performance will be influenced.
1.2.14.4. If the cable or motor inner has the short circuit, the inverter will make
the alarm or it will be exploded, please perform the insulation short-circuit test for
the initially-installed motor and cable, and this test is also often conducted in daily
maintenance. Please pay attention to that when conducting this test, please switch
off the inverter and all tested parts.

2.7 Daily maintenance of inverter
2.7.1 Daily maintenance
The effect of temperature, humidity, dust and vibration leads to the aging of inner
parts of inverter,potential fault or reduction of service life of inverter. Therefore, it is
necessary to implement the daily and regular maintenance for inverter.
After switching off the power, if the filter capacitor still has the high
voltage, the inverter can't be maintained immediately, only waiting
the charge lamp goes out ,and the bus voltage measured by the
multimeter should not exceed 36V, the maintenance can be performed.

5）Main circuit insulation test
Reminder: When testing the insulation resistance with the megohmmeter (DC 500V
megohmmeter), separate the main circuit lines from the inverter. Never use the insulation
ohmmeter to test the insulation of control circuit. HV test needn't to be performed, because
this test has been finished before the inverter leaves factory.
2.7.3 Change of wearable parts of inverter
The wearable parts of inverter include the cooling fan and electrolytic capacitor for
filtering, their service life is closely related to the service environment and maintenance
status. In general, their life is shown as follows:
Fan
Electrolytic capacitor
Service life
2~3 years
4~5 years
User can determine the age limit according to the running time.
1） Cooling fan
Possible cause for damage: Bearing abrasion and blade aging.
Examination standard: Check whether the fan blade has the crack, whether the fan has
the abnormal vibration when it is started.
2）Electrolytic capacitor for filtering
Possible cause for damage: Bad quality of input power, higher environment temperature,
frequent jump of load, aging of electrolyte.
Examination standard: Leakage of liquid, projection of safety valve, and test of static
capacitance and insulation resistance,
2.7.4 Storage of inverter
After user purchases the inverter, please pay attention to following points for temporary
storage and long-time storage.
1）Put the inverter with the original package into our packing case when it is
stored.
2）The long-term storage will result in degradation of electrolytic capacitor, so,
the inverter must be electrified once every two years, the electrified time should be
5hours at least, the input voltage should rise to the rated value step by step with
the voltage regulator.
2.8 Guidance for selecting type
Two control modes are available: Common V/F control and SVC control.
When selecting the inverter, first, you must identify the system technical requirements of
frequency-conversion speed regulation, application location of inverter, load characteristics,
etc., and take the applicable motor, output voltage, rated output current, etc. into the
consideration, then to select the machine type at your request and determine the running
way.
Basic principle: The rated load current of motor should not exceed the rated current of
inverter, in general, select the inverter according to the applicable motor capacity that is
specified as the manual, please compare the rated current of motor with that of inverter. The
overload capacity of inverter makes actually sense to the starting and braking operation.
Whenever the inverter has the short-time over load, the load speed will be changed. If the
speed accuracy is demanding, please take a higher class into account.
Fan and water pump type: The overload capacity is undemanding. Because the load
torque is directly proportional to the square of speed, the load (except the rose fan) is very
light when it runs at a low speed. And, these loads have no special requirements on the
rotation accuracy, so, the square torque V/F is selected.
Constant-torque load: Many loads such as the extruder, agitator, conveyer belt, plant
trolley, crane translating mechanism have the constant-torque characteristics, however,
their rotation speed and dynamic performance are undemanding. Accordingly, multi-
segment V/F operation way is available when choosing the type.
The controlled object has a certain dynamic and static state requirement. The strong
mechanical characteristics are required for this type of load when it runs at a low speed, to
meet the control system requirements of dynamic and static indicators. SVC control way is
available.
Chapter 3 Mechanical and electrical installation
3.1 Mechanical installation
3.1.1 Installation environment
1）Environment temperature: The ambient temperature has a large impact on
the service life of inverter, the running environment temperature of inverter should
not exceed such temperature range （-10℃～50℃）.
2）The inverter is installed on the surface of flame-retardant object, it should
have the enough space for ventilation, because it produces much heat easily when
working. And, it should be vertically installed at the mounting rack with the screw.
3）Please install it in the firm area without easy vibration occurrence. The
vibration should not be more than 0.6G. Especially, it should be kept away from
the punch.
4) It is installed in the area free from the direct sunlight, dampness and drip.
5）It is installed in the area free from the corrosive, flammable, explosive gas,
etc..
6）It is installed in the location free from the oil pollution, much dust and
metallic dust.

Note: When the inverter is installed vertically, please mount a heat-insulated
baffler shown as fig. 3-2.
Please pay attention to the following points about heat emission when performing
the mechanical installation.
1）The inverter should be installed vertically, which enables the heat to emit
upwards easily, but it should not be mounted reversely. If many inverters need to
be installed in a cabinet, you'd better install them side by side. If the inverters
need the top and bottom installation, please mount a heat-insulated baffler shown
as fig. 3-2.
2）Make sure the inverter has the enough space for heat emission, the
installation space is shown as fig. 3-1. However, when laying it, please consider
the heat emission of other parts in the cabinet.
3）The mounting rack must be made of the flame-retardant material.
4）For the area with full metallic dust, it is suggested the installation outside the
cabinet of radiator should be adopted, and, the space inside the full-seal cabinet
should be as large as possible.
