14.3.8. Replacing Filter Capacitor Board Assembly (A7)

• See also Service Instruction (JD5078-00).

The Filtering Board assembly (A7) consists of a capacitor bank (C1x) and bleed resistor (R9x) mounted on a printed circuit board.

Preparation:

• Shut down and lock out all power to ATevo.
• Wait several minutes to allow internal voltage potentials in capacitors to bleed off.
• Remove safety shield and check with a voltmeter.
• Along left side of ATevo, locate the Filter Capacitor Board (A7) assembly on top of heatsink, above power board and rectifier.

Removal of Existing Capacitor Board Assembly:

• Remove (2) nuts from studs connecting Power Board (A2) to Capacitor Board (A7).
• Remove (1) screw at top center of Capacitor Board.
• Remove existing capacitor board assembly.

Installation of New Capacitor Board Assembly:

• Place new Capacitor Board Assembly (A7) onto studs on Power Board (A2) and replace (2) nuts and (1) screw.
• Replace safety shield, close front panel door.
• Restart ATevo.
