REPLACING THE BATTERIES
WARNING!
This uninterruptible power source contains potentially
hazardous voltages. It is recommended that you turn the UPS off and
disconnect the input power cord from the receptacles prior to connecting or
disconnecting the battery terminals. Only UPS’s that have external battery
packs can be changed “HOT”, that is with your AC power connected to the unit, and
while supplying power to your equipment. If battery pack(s) MUST be changed while
power is on, they can only be changed while the AC line is supplying power to the
protected equipment. Be EXTREMELY careful while plugging or unplugging additional
