Parts For Regular Replacement; Storage - Powtran pi130 series User Manual

"√" means routine or regular check to be needed
Do not disassemble or shake the device gratuitously during check, and never
unplug the connectors, otherwise the system will not run or will enter into fault state and
lead to component failure or even damage to the main switching device such as IGBT
module.
The different instruments may come to different measurement results when
measuring. It is recommended that the pointer voltmeter shall be used for measuring
input voltage, the rectifier voltmeter for output voltage, the clamp-on ammeter for input
current and output current, and the electric wattmeter for power.

9-2.Parts for regular replacement

To ensure the reliable operation of inverter, in addition to regular care and
maintenance, some internal mechanical wear parts (including cooling fan, filtering
capacitor of main circuit for energy storage and exchange, and printed circuit board)
shall be regularly replaced. Use and replacement for such parts shall follow the
provisions of below table, also depend on the specific application environment, load and
current status of inverter.

9-3.Storage

The following actions must be taken if the inverter is not put into use immediately
(temporary or long-term storage) after purchasing:
※
It should be stored at a well-ventilated site without damp, dust or metal dust, and
the ambient temperature complies with the range stipulated by standard
specification
※
If the time that the inverter is set aside exceeds one year, a charge test should be
made so as to resume the performance of the filtering capacitor of main circuit.
When charging, the voltage regulator can be used to slowly rise input voltage of
the inverter until the rated input voltage, the charging time is 1 to 2 hours or more.
The above test shall be performed at least once a year.
