Preparation for Inductor Removal:

• Shut down and lock out all power to ATevo.
• Remove safety shield.
• Disconnect the battery and dc load(s) from the DC Output Circuit Breaker (CB2+/-).
• Check with a voltmeter before proceeding, including any installed remote sense wires.
• Remove enclosure shroud.
• For Main Filter Inductor (L1), disconnect wires labeled ‘L1-1’ and ‘L1-2’ at Power Board lugs.
• For Secondary Inductor (L2), disconnect wires labeled ‘L2-1’ and ‘L2-2’ at Power Board lugs.

	The Filtering Inductors (L1 & L2) are heavy. Be prepared to support their weights before proceeding.

• Remove two (2) screws at top corners of the inductor mounting plate.
• Carefully lift the existing Inductor (L1 or L2) out of the bottom slots, and off of the enclosure back wall.
• Position new Inductor (L1/L2) with same orientation as existing.
• Slide inductor into bottom slots, making sure top mounting holes in plate align with holes on enclosure back wall.
• Install mounting screws into top corners of inductor plate.
• Route wires (natural leads) from inductor to corresponding lugs labeled on Power Board (A2).
• Insert wires into lugs and tighten.
• Check your work.
• Replace safety shield and close the front panel door.
