UPS Maintenance

Replacing Batteries

NOTE DO NOT DISCONNECT the batteries while the UPS is in Battery mode.

With the hot-swappable battery feature, UPS batteries can be replaced easily without turning the UPS off or disconnecting the load.

If you prefer to remove input power to change the battery: 1) Press and hold the Off button until the long beep ceases (approximately five seconds), then unplug the UPS; 2) Wait 60 seconds while the internal processor shuts down before you disconnect the battery.

Consider all warnings, cautions, and notes before replacing batteries.
