1. WhichEBP’sdoIconnecttoanACinputsource?
• It is possible to plug in every EBP into an AC input source. The more connected the
faster the recharge time. It is recommended
 that every third EBP be connected to
incoming AC utility to properly charge the batteries in a complete system. Leaving too
manychargersconnectedmay causean overcharge situationwhichcoulddamage the
batteries.
2. WhichLED’saresupposedtobelitonthefrontofeachEBP?
• WhenanEBP isconnectedtoanACinputsourceandtheunitischarging,aGREENLED
onthefrontoftheEBPwillbeilluminated.
3. Are any LED’s  on the front of the EBP supposed to be lit if it is not connected to an AC input
source?
• No.TheUPSand/ortheEBP’sthatarepluggedintoanACinputsourceareresponsible
for charging the entire system. The EBP is still working and has the capability of
