12.2 Connections to Auxiliary I/O Board

12.2.1 System Connections

The Auxiliary I/O Board (A4) plugs into the top of the Power Board
(A2). All system connections are factory wired when the Auxiliary I/O
option is ordered with the ATevo.

12.2.2 Wiring Relays Connections

Connections to the relays are made through an 18-position terminal
block (A4-TB4). Connections to the six (6) programmable relay
contacts are clearly labeled on the board.
PROCEDURE
1. De-energize and lock out all ac and dc voltages to ATevo.
2. Allow internal voltages to dissipate.
3. Remove safety shield and verify no hazardous voltages are
present with a voltmeter.
4. Route remote annunciator wiring to Auxiliary I/O Board (A4)
through an unused enclosure knockout.
5. Connect wiring (use #22-14 AWG) to appropriate terminals on
the Auxiliary I/O Board (A4-TB4).
6. Strip each wire 0.25in / 6.4mm, and tighten terminal screws.
7. Replace the safety shield and close the front panel door.
8. Re-energize ATevo.
NOTES
• Alarm contacts are rated at 0.5A @ 125 Vac/Vdc.
• Signal terminal block (A4-TB4) is compression type, accepting
#22-14 AWG wire.
• Terminals are labeled in non-alarm condition.
