8.1.4 Measure of Inverter
Because there is high-order harmonic wave in the input& output voltage and current,
the choice of wrong measure instrument will induce big measure inaccuracy. Suggest
measure by the instrument as follows:
Item

Output
Voltage
Current
Power

8.1.5 replace of components
Differ ent Inv erter c ompone nts hav e different operating life, meanwhile, the
operating environment also change their operating life, in order to let the Inverter
work normally and chronically, should replace some of the components according to
the conditions. Suggest the approximate change time as the table below:
Name of components
Replace time
Cool fan
Electroanalysis capacitance
Print circuit board
Other device
2-3 years
4-5years
5-8years

examination conditions
Transportation and Deposit
8.2.1 transportation of Inverter
put the Inverter upward when transport it, acutely quiver,
impulse or heavy press is not allowed, and also should avoid rain
and snow.
8.2.2 storage of Inverter
If the transport need temperate keeping or long-term storage, but not be used
immediately, should pay attention to the following points:
The storage temper ate should be within the bound of 20 to +60, and also
the ground should be not humid, no dust, no metal power and ventilated.
if the Inverter not be used more than one year, should process charge
test to revive the characteristic of the main circuit filter capacitance in the
Inverter.
when charging the Inverter, rise the vol tage slowly till up to the rated
input voltage, the charge time should be within 1 to 2hours.
