12.2.2. 12.2.2. Wiring Relay Connections Wiring Relay 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 Procedure
1. De-energize and lock out all external 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 (#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. Restart ATevo.
Notes Notes
• Alarm contacts are rated at 0.5A @ 125 Vac/Vdc.
• Signal terminal block (A4-TB4) is compression screw type, accepting #22-14 AWG wire.
• Terminals are labeled in the non-alar
relays energized.
*
Not 'shelf state'
• If user alarm contacts (A4-TB4) are to drive inductive dc loads (e.g. a larger dc relay) an
external protective diode must be installed at the dc relay to avoid equipment damage.
Refer to Application Note Application Note (JD5011-00).
