Hello Sazzad, Please install a mesuring device like a power meter to monitor voltage fluctuations along 24 hr/day. I am very much sure that the problem is comming from the fluctuations and it is very important to have a record for the problem in order to avoid more MM4 failures. And I do recommend not to install more MM4 drives withoutLine commutating chocke
Attached a document that show you in a simple way how to measure % line impedance.
