9-4. Measuring and Judgment
※
If the current is measured with the general instrument, imbalance will
exists for the current at the input terminal. Generally, differing by not
more than 10% is normal. If it differs by 30%, inform the factory to
replace the rectification bridge, or check if the error of three-phase
input voltage is above 5V.
※
If the three-phase output voltage is measured with a general
multi-meter, the reading is not accurate due to the interference of
carrier frequency and only for reference.

10-1. MCCB OR ELCB
As power switch of the inverter, MCCB or ELCB can protect supply power,
but can't control inverter to run or stop.
10-2. Noise filter
The filter is used to restrain the conduction of electrical magnetic wave
interference noise produced by the converter or shock the interferential form
