IMPORTANT
Checking string polarity must be conducted separately for each battery string (pair of battery trays). These
checks also assure that all battery-to-battery jumpers in the battery tray assemblies are connected. Be sure to
disconnect the current battery tray pair before moving to the next pair. Strings should not be connected in
parallel until after each and every string polarity has been verified. Failure to do this could result in a serious arc-
flash injury
