Rectifier Current Sharing Unbalance
When multiple rectifiers are operating in parallel and the current sharing unbalance
among them is greater than 3%, check if the communications cables are correctly
connected.
If the current sharing unbalance still persists, following the verification suggested above,
then replace the rectifier which has had its current sharing function disabled.
