SUMMARY: An assembly error may allow a mounting screw to damage the output filter

capacitors.

OPERATIONAL IMPACT: When the screw shorts to the case of the capacitor, arcing can occur

damaging the filter network.

ACTION: Remove the bottom, right, side panel. Locate the output filter assembly (C2-C6).

Inspect the mounting screws used to secure C2-C7 to the holding bracket of the MM250, If the

screw on either end is touching the capacitor it must be replaced with a shorter screw. See

enclosed photographs.
