• Replacement module for compact control cabinets

Key specifications

• Nominal voltage: 12 V
• Capacity: 7 Ah
• Battery chemistry: sealed lead-acid (SLA)
• Maintenance: valve-regulated, low-maintenance design
• Intended use: short-term backup for low-current access and automation systems
• Physical form: compact sealed module suitable for cabinet installation

How to use

Install the module in the designated compartment of the control unit or mounting bracket, observing polarity when connecting the positive and negative terminals. Ensure the installing system is powered down or in a safe state during replacement. After connection, verify charging current and status indicators on the host device, and confirm that the backup functions activate correctly during a simulated mains failure. Follow the installation instructions provided by the primary equipment manufacturer to maintain warranty and functional compatibility.

Recommendations

Store and operate the module at temperatures recommended for sealed lead-acid batteries, avoid deep discharges where possible, and replace the module at end-of-life or when capacity degradation compromises backup time. Periodically test backup operation as part of routine maintenance to ensure dependable emergency power when mains interruptions occur.
