Firmware Flash Compatibility and RAM Retention Protocols
The IC693ACC302 interfaced directly via dedicated 2-pin battery connectors delivers sustained 3 VDC power to preserve non-volatile CMOS logic registers and system firmware flash parameter pointers during main backplane power de-energization. Integrating high-capacity internal chemistry rated at 15 Ah allows extended retention periods up to 75 months. Deterministic voltage delivery prevents volatile RAM data corruption across host CPU modules without interrupting backplane bus arbitration cycles during power-up or shutdown transitions.
Frequently Asked Questions
Q: What is the physical connection interface for the IC693ACC302 battery module?
A: The module connects to host CPU hardware using a 24 AWG twisted red and black wire harness terminated with a 2-pin female keying connector.
Q: How long can the IC693ACC302 maintain volatile RAM contents when main backplane power is removed?
A: The module provides continuous memory retention power for up to 75 months under standard operating thermal limits ranging from 0 to 60 deg C.
Field Installation Guidelines
- Mount the battery module securely to a vertical panel using the designated mounting holes, ensuring adequate distance from high-heat output devices inside the enclosure.
- Connect the 2-pin female harness connector directly to the matching male battery header on the target Series 90-30 or PACSystems CPU board.
- Ensure polarity alignment (red positive wire, black negative wire) when seating the keyed wire harness connector.
- Do not expose the ABS plastic housing to environmental temperatures exceeding 60 deg C or open flames.
