9.3 Preservation and maintenance
If the frequency inverter is not in use immediately after purchased, and need
to be temporarily stored or long-term stored up, pls obey belowing rules:
9.3.1 Frequency inverter should be stored in the place with standard
temperature range、 fine ventilation and no humidity、 dust or metal
dust.
9.3.2 If frequency inverter has not been put into use yet for more than 1
year, user should carry on charging testing to restore the
characteristic of the inner main circuit filter capacitor. During
charging, user can use the pressure regulator to elevate slowly the
input voltage of the frequency inverter to the rated input voltage.
The charging time should be above 1-2 hours. At least test once every
year as narrated above.
9.3.3 Frequency inverters are not allowed to be carried out the pressure
testing, otherwise, it will lead to frequency inverter life lessening
or damage. Before the insulation testing, user should use 500 MΩvolt
megger measures the frequency inverter. Its insulation resistance
should not smaller than 4MΩ
9.4 Measurement and judgment
When using the general ohmmeters to measure current, the current in the
input end will has imbalance phenomenon. Generally the difference within 50%
is regular. If using general multimeter to measure the output three-phase
