• If the new DC-EMV is not equipped with
varistors, take the varistors from the old DC-
EMV using the insertion tool (STP-IT). Keep the
varistors in a safe place for later use on the
new DC-EMV.
7 Installing the DC filter assembly

• Connect the cables to the ESF. When doing so,
ensure that the assignment is correct.
