The IC695ACC403 delivers regulated hold-up energy to the PACSystems RX3i CPU during main supply dropouts, preserving internal system registers and user application memory. By executing autonomous power transfer without disturbing backplane bus communication velocity, the unit prevents controller halt cycles during momentary voltage transients. Firmware flash compatibility across connected CPU modules ensures synchronized diagnostic reporting through the front-panel status LED, maintaining data integrity without hardware jumper reconfiguration.
Q: What are the physical clearance requirements when mounting the IC695ACC403 module?
A: The IC695ACC403 requires a minimum clearance of 25.4 mm (1 in) around the unit to facilitate adequate thermal convection and heat dissipation.
Q: Can the IC695ACC403 module be exposed to direct water spray or high moisture environments?
A: No. The IC695ACC403 is not water splash resistant and must be installed inside a protective NEMA or IP-rated enclosure where ambient moisture is managed.
Q: What wire gauge is recommended for connecting power and ground to the screw terminals?
A: The screw terminals on the IC695ACC403 are designed to accept #18 AWG wiring for DC power inputs and frame grounding.
