Operation and Features SPD’s do not require a great deal of operator intervention after installation. NOTE: The PM Series has a green LED for each phase which extinguishes when the module is no longer providing protec-tion (fault condition). All of the PM Series of SPDs contain a diagnostic circuit ...
