Replacing Auxiliary I/O Board
Preparation: Preparation:
• 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.
Wires connected to the Relay Outputs (A4-TB4), Binary Inputs (A4-TB1), and
Analog Inputs (A4-TB3) may still have wetting voltages or signal voltages
present.
Removal of Existing Auxiliary I/O Board: Removal of Existing Auxiliary I/O Board:
• Analog Inputs terminals (A4-TB3) and Binary Inputs terminals (A4-TB1) are removable. If
any wires are present on these terminals, pull the terminal blocks out of their sockets.
• Remove wires connected to Relay Output terminal block (A4-TB4).
• Remove (4) screws that connect Auxiliary I/O Board (A2) to Heat Sink Assembly (A6).
• Remove Auxiliary I/O Board (A4) from Rectifier / Heat Sink Assembly (A6) by pulling it
forward, toward front of ATevo.
Installation of New Auxiliary I/O Board: Installation of New Auxiliary I/O Board:
• Align header socket at top right of Auxiliary I/O Board (A4) with header pins on Power
Board (A2).
• Push Auxiliary I/O Board onto header pins of Power Board and align (4) mounting holes
with standoffs on Heat Sink Assembly.

Assembly Assembly
For ATevos rated 30-50 Adc, the Filtering Assembly (A7) consists of a capacitor bank (C1x) and
bleed resistors (R9x) mounted on a printed circuit board. ATevos rated 75-100 Adc, feature
discrete blue electrolytic filter capacitor 'cans' (C1x).
Preparation: Preparation:
• Shut down and lock out all power to ATevo.
