instructions
1.2.9 Others
CAUTION
During transport or under any specific condition, the inverter may not be placed in a
halogen (fluorine, chlorine, bromine, iodine) environment. Otherwise, the inverter may
be damaged or its components will be burned out.
1.3 Precautions
1.3.1 Motor insulation inspection
When the motor is used for the first time, or reused after storing for a long time, or
in a regular inspection, the user must inspect the insulation of the motor to prevent
the poor insulation of the windings of motor from damaging the inverter. The motor
connection must be divided from the inverter during the insulation inspection. It is
recommended to use a 500 V Mega-Ohm-Meter and the insulation resistance shall
not be less than 5 MΩ.
1.3.2 Thermal protection of motor
If the rated capacity of the motor selected is not matching that of the AS500 series
inverter, especially when the rated power of the inverter is greater than that of the
motor, make sure to adjust the parameters for motor protection inside the AS500
inverter or to install a thermal relay to the motor to guarantee the protection to the
motor.
1.3.3 Motor heat and noise
Since the output voltage of the inverter is PWM wave with some harmonic, the
temperature rise, noise and vibration may increase compared with the inverter
running at power frequency.
When a conventional motor driven by an inverter is in prolonged low speed
operation, the motor temperature will rise because the heat dissipation effect of the

1-8

Cha
p
ter 1Safet
y
instructions
motor becomes poorer. If a prolonged constant-torque low-speed operation is
required, a variable frequency motor must be selected, or forced air cooling be
provided.
1.3.4 Caution to input and output
Because the AS500 inverter outputs PWM wave, the capacitor used for improving
power factor and piezoresistance used for lightening-proof should not be installed
at the output side of the inverter. Otherwise the inverter may have transient
over-current and may be damaged.
No permission for capacitor connection at the output side of the inverter refers to
Figure 1-1.
Figure 1-1 Schematic diagram for non-permission for capacitor connection at the output side of the
inverter
If a contactor is required to be installed between the inverter input terminal and the
power supply, it is prohibited to start or stop the inverter with the contactor.
If switches like contactors are connected between the output terminal and the motor,
make sure to start and stop the inverter when the inverter has no output, it is
prohibited to pick up the contactor when the inverter is outputting, otherwise the
modules in the inverter may be damaged.
Terminals are recommended for the startup / shutdown of the inverter. The user is
absolutely not permitted to directly shut down or start up the inverter via such
switches as contactor on the input terminal of the inverter; otherwise, damages to
equipment may be caused.

instructions
1.3.5 Usage out of the Range of Rated Voltage
The AS500 series inverter shall not be used out of the specified range of operating
voltage. Otherwise, the internal components of the inverter may be damaged. If
needed, please use corresponding voltage regulation device to change the voltage.
1.3.6 Lightning Strike Protection
There are lightning over current protection devices inside the inverter, which has
certain self-protection capacity for sensing the lightning. The user should install
other lightning protection device at the front end of the inverter where lightning
strike occurs frequently.
1.3.7 Leakage protection
Quick startup or shutdown during inverter operation necessarily induces
high-frequency leakage currents, which may sometimes cause misoperation of the
leakage protection circuit. In the event of the aforesaid problems, reduce the carrier
frequency and the length of the lead-in wire appropriately; besides, the leakage
protector must be correctly installed.
Keep the following points in mind when installing a leakage protector:
It is more proper to install the protector at the input terminal of the inverter and
behind the air circuit breaker (not a fuse circuit breaker).
The selected leakage protector must be insensitive to higher harmonics
(sensitivity: Above 30 mA) or specially suited for inverter applications. If a common
leakage protector is selected, it must have the sensitivity above 200 mA and the
action time above 0.1 s.
1.3.8 Derating
When the ambient temperature exceeds 40 , the inverter must be derated by 1%℃
for every increment of one degree Celsius. Also, forced external heat dissipation
must be provided.
At 1,000 m above sea level, the thinner air will deteriorate the heat dissipation effect

1-10
Shanghai Sigriner STEP Electric Co., Ltd.
Cha
p
ter 1Safet
y
instructions
of the inverter. Therefore, the inverter must be derated by 1% for every increment of
100 m.
When the set carrier frequency exceeds the factory settings, the inverter must be
derated by 10% for every increment of 1 kHz.
For derating, please contact our company for detailed technical support.
1.3.9 About applicable motor
The inverter is applicable to asynchronous squirrel-cage motor and permanent
magnet synchronous motor. Please be sure to select the applicable inverter
according to the Nameplate of the motor.
The inverter has already been configured with default parameters which are
applicable to asynchronous squirrel-cage motor. To perform the motor parameter
identification according to the actual conditions will promote the operation effect.
The short circuit of cable or motor interior may cause the inverter alarm or to be
damaged. Therefore, perform insulation short test for the initially installed motor
and cables, and also make such test during the routine maintenance. Please make
sure that the inverter be cut from the testing parts when the test is undergoing.
