5. Operating Instructions
5.1 Initial Power-Up
After connecting the external battery cabinet to the UPS, power on the UPS system according to its specific user manual. The UPS will automatically detect the connected battery cabinet(s) and adjust its runtime calculations accordingly.
5.2 Monitoring
Monitor the battery status and runtime information through the UPS display or management software. The added battery capacity from the external cabinet will be reflected in the UPS's reported runtime.
5.3 Extending Runtime
The primary function of the GXT5-EBC48VRT2U is to provide extended runtime for your connected equipment during a power outage. When the UPS switches to battery mode, the external battery cabinet will seamlessly provide additional power, allowing for longer operation or a more graceful shutdown of critical systems.
6. Maintenance
6.1 Battery Care
- The GXT5-EBC48VRT2U utilizes lead-acid batteries. These batteries are designed for long life, especially with the integrated external temperature compensation sensors that help optimize charging based on ambient temperature.
- Avoid frequent deep discharges, as this can shorten battery life.
- Ensure the battery cabinet is kept in a well-ventilated area to prevent heat buildup, which can degrade battery performance.
- Battery replacement should only be performed by qualified service personnel.
6.2 Cleaning
Periodically clean the exterior of the battery cabinet with a soft, dry cloth. Do not use liquid or aerosol cleaners, as they may damage the unit or pose an electrical hazard.
