5. SYSTEM BATTERIES
The batteries used in the XRT series of UPS’s and the XRTBP battery packs are sealed,
When batteries are replaced, dispose of the batteries according to local regulations or return the batteries to your dealer or distributor for proper disposal. If you cannot dispose of the old batteries, they may be returned to Minuteman for proper disposal. Call Minuteman Technical Support for instructions on returning the batteries.
NOTE: Only the XRTBP battery packs are to be used with the XRT units. The XRT UPS has the DC battery negative terminal tied to the AC ground at the remote communications port. Other battery systems may have the DC battery positive terminal tied to AC ground. This would result in a direct short and may damage the unit and void your warranty.
STORAGE INSTRUCTIONS
If the UPS is to be stored, allow the batteries to fully charge for 24 hours, then store the unit in a cool, dry location. For extended storage in moderate climates, the batteries should be charged for 8 hours every 3 months. Repeat this operation every 2 months in high temperature locations.
