Mode of Connection

For safe operation,the items below for maintenance and check should carried out.

Checking Points

Solutions

If the temperature is still normal.

When temperature rises abnormally (above15), which is created by either the failure or the inproper ambient temperature (-40~+45).
the causes should be investigated.

If it is rusty.

Adopt rust-proof teratment such as the derusting coating.

If there is opening on the outer casing

If there is opening on the outer casing, the capadtof should be replaced for a new one.

If it is exposed to the rain or water.

Change the installation place.

If the set screw is loosen.

For the cause of vibrtion. the solution to the problem is to change the installation place or to take anti-vibration measures.

If there is iron powder or dust accumulated.

If there is too much such iron power or dust, the installation, place should be changed ;and itcan be cleaned by bruch when there is a little.

If the outer casing is swelling.

The swelling is caused by the starting of the protector. Investigate the cause of capacitor damage and replace the old capacitor for a new one

If there is oil leakage.

Check if there is opening on the outer casing, and replace the old capacitor for a new one at once.
