Because the output voltage of the inverter is the PWM wave
，
it
contains some harmonics wave, Therefore, there will be some increase in
temperature
、
noise
、
libration in motor and work-frequency.
Varistors for surge protection and capacitors used to improve the
Power Factor
Don’t connect any varistor or capacitor to the output terminals of the
inverter, as the inverter output voltage waveform is pulse wave.
Otherwise, it may cause tripping or damage to devices.
If the circuit breaker or contactor needs to be connected between
the inverter and the motor, please only operate them when the inverter
has no output. Do not turn off the contactor when the inverter is active. It
is to avoid damage to the inverter. Otherwise it may cause damage to the
devices.
Using outside rated voltage
The inverter could not be used at an operating voltage out of the
specified range. If needed, please use suitable voltage regulation device.
Try to change the three-phase input into two-phase input
It’s not permitted. Don’t use the three-phase inverter as a two-phase
one, or it will result in failure or damage.
Protection against lightning stroke
There are transient surge suppressors inside the inverter. They can
protect it against lightning stroke. If it is in frequent lightning stroke area,
more protection device should be added in the leading end.
Derating due to altitude
Derating must be considered when the inverter is installed at a
high altitude, above 1000m. The cooling effect of the inverter is less
effective in the thin air. For more details, please contact your local
supplier or A-TS.
For some special usages
If the customer needs to use the wiring diagram that the manual
did not mentioned, such as the common DC bus, please contact local
supplier or A-TS.
