Series 90-30 GE Fanuc IC693ACC302 Battery Modules

The GE Fanuc IC693ACC302, also cataloged as the IC693ACC302 Auxiliary Battery Module, operates as a dedicated hardware component for continuous voltage maintenance within Series 90-30 Programmable Logic Controller assemblies.

Hardware Specifications

Backplane Bus Communication Velocity and Firmware Flash Compatibility

The hardware contains an internal isolated current delivery path that links directly to the peripheral logic rails of the local chassis, maintaining zero load influence over the main backplane bus communication velocity data packets. While lacking active communication controllers, the assembly preserves volatile internal registers, configuration maps, and system application execution blocks across structural power drops without generating hardware synchronization exceptions. The continuous current delivery pattern ensures consistent firmware flash compatibility baselines during unexpected power loss cycles, blocking systemic logic register degradation when the system scales via complex distributed layouts linked to Profinet or EtherNet/IP deterministic networks.

Frequently Asked Questions

Q: Does the IC693ACC302 auxiliary battery module support hot-swap replacement while the PLC system is running?

A: Yes. The module can be replaced while the primary power supply of the PLC rack is energized. The internal primary capacitor on the CPU card maintains the memory registers for a maximum duration of 30 minutes, allowing sufficient time to swap out the spent cell without losing logic applications.

Q: What are the restrictive parameters if the polarization on the 2-pin cable interface is reversed?

A: The physical design of the 2-pin female connector contains a keyed molded plastic shell that matches a corresponding male guide slot on the CPU housing. This structure prevents physical reversal of the pins, shielding the logic components from destructive reverse polarity currents.

Field Installation Guidelines

• Mount the external battery containment bracket to the subpanel adjacent to the baseplate assembly using standard hardware fasteners, verifying that it resides out of the path of dropping condensation.
• Route the polarized lead wires through local enclosure tracking slots, ensuring that the cable jacket remains uncompressed by high-voltage terminal lines or mechanical hinge points.
• Verify that the terminal connection pin engagement locks fully into the matching receptacle on the Series 90-30 CPU card to avoid high-resistance vibration disconnections.
• Dispose of the replaced lithium cell according to local environmental regulation constraints, keeping the old battery assembly away from heat radiation sources exceeding 100 deg C.
