Usage Notes

This CPU motherboard is exclusively designed for B&R APC620 series chassis; it is incompatible with other B&R IPC models (e.g., APC810, APC910) or third-party industrial chassis. When installing the board, strictly follow anti-static procedures (use ESD mat and gloves) to avoid electrostatic damage to components. Ensure all power and data cables are securely connected to prevent loose contacts and system instability. The onboard battery must be replaced every 2.5 years to maintain RTC accuracy and BIOS settings; use only the specified 3 V lithium battery (0AC201.9). Do not install non-compatible memory modules (e.g., DDR2/DDR3, ECC) as this may cause system boot failure or damage to the board. Regularly clean the board and connectors every 3–6 months based on on-site environmental conditions to prevent dust accumulation and ensure reliable operation. For ambient temperatures above 45°C or continuous high-load operation, install the optional chassis fan kit to enhance thermal dissipation and prevent overheating.
