Assembly (A7 or C1x) Assembly (A7 or C1x)
For ATevo models rated 16-50 Adc, the Filtering Assembly (A7) consists of a capacitor bank
(C1x) and bleed resistors (R9x), mounted on a printed circuit board. Models rated 75-100 Adc,
feature discrete blue electrolytic filter capacitor 'cans' (C1x).
Preparation: 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.
For ATevo models rated 16-50 Adc: For ATevo models rated 16-50 Adc:
• See also Service Instruction (JD5078-00).
• Along left side of ATevo, locate the Filter Capacitor Board (A7) assembly on top of
heatsink, above power board and rectifier.
Removal of Existing Board: Removal of Existing Board:
• Remove two (2) nuts from studs connecting Power Board (A2) to capacitor board.
• Remove one (1) screw at top-center of Filter Board.
• Remove existing capacitor board assembly.
Installation of Replacement Board: Installation of Replacement Board:
• Place new Filter Board (A7) onto studs of Power Board, and replace two (2) nuts and one
(1) screw.
• Replace safety shield, and close front panel door.
• Restart ATevo.
For ATevo models rated 75-100 Adc: For ATevo models rated 75-100 Adc:
• See also Service Instruction (JD5078-01).
• Locate the C1 discrete capacitor can(s) near the top-left of the enclosure.
Removal of Existing Capacitor (C1x) Assembly: Removal of Existing Capacitor (C1x) Assembly:
• Remove the screws attaching the capacitor to connection wires and/or bus bar.
• Loosen the screw on the capacitor bracket at the bottom of the capacitor mounting.
• Make note of polarization ± of the capacitor screw terminals.
• Remove capacitor(s) from bracket(s).
