The Yokogawa HHR-30HF5G1, also cataloged as the HHR-30HF5G1 Battery Back-up System, operates as a dedicated hardware component for auxiliary energy storage and uninterrupted power supply maintenance within industrial automation platforms.

Hardware Specifications

Energy Storage and Standby Power Performance

The HHR-30HF5G1 functions as a high-capacity energy reservoir, utilizing lead-acid chemistry to provide 12 VDC output to critical control system components during primary power interruptions. The system is engineered to handle the discharge characteristics required by PLC controllers, I/O modules, and field instrumentation buses. Its design incorporates standard terminal interfaces to ensure compatibility with industrial power distribution cabinets, allowing for integration into UPS (Uninterruptible Power Supply) logic paths to maintain process uptime and data retention functionality during transient line failures.

Frequently Asked Questions

Q: Can the HHR-30HF5G1 be connected in parallel with other battery units?

A: Yes, parallel connection is possible to increase total ampere-hour (Ah) capacity. However, all connected units must be of the same model, age, and state of charge to prevent cross-charging currents that may lead to premature degradation.

Q: What is the optimal maintenance cycle for this lead-acid battery?

A: Periodic inspection of terminal connections for oxidation and voltage checks at 6-month intervals are required. The battery should be replaced if the internal resistance significantly increases or if the capacity fails to meet the system's defined hold-up time requirements.

Field Installation Guidelines

• Ensure the battery is installed in an upright position to prevent electrolyte leakage and to facilitate proper gas venting through the integrated relief valves.
• Verify that the cabinet or enclosure provides adequate ventilation, as lead-acid batteries can generate hydrogen gas during charging cycles.
• Utilize appropriately sized copper conductors for all DC power connections to minimize voltage drop between the battery and the protected equipment.
• Secure the unit within the rack or shelf using mechanical brackets to prevent displacement due to industrial floor vibrations.
• Conduct a discharge test upon initial commissioning to confirm that the battery supplies the expected 12 VDC under the rated system load.
