Periodic Maintenance
Periodic Off-Line Maintenance Recommendation
Depending on the operating environment, a six-monthly internal inspection by an authorized person is highly
recommended. During this inspection, if any dust has accumulated, it can be vacuumed/removed, and air filters cleaned
and/or replaced. At the same time, verify the integrity of the cable connections to ensure that they are tightly fastened.
Periodic On-Line Diagnostic Test
This is recommended to be done once in six months by the client or maintenance staff. The unit will continue to
operate normally automatically while the diagnostic test is conducted.
When you turn on 27.5 KVAR, 55 KVAR or 82.5 KVAR, the current flowing will be nearly same as the values that have
been mentioned in the DEFAULT CURRENT table below.
