DANGER:
After connectors are mated, power bus will be "live" (i.e., have voltage on
it).
Connect together gray connectors on STR( ) (1, 2, or 3) battery string cable
and STR( ) (1, 2, or 3) cable from control & distribution panel.
26. Dress and secure cables to the top of the battery compartment as necessary
to keep them above batteries (in case of flood).
27.
NOTE:
To measure battery string voltage accurately, disconnect any battery
strings other than battery string being measured. [To disconnect other
battery strings, unplug STR( ) battery string cable connector (gray) from
STR( ) battery cable connector (gray) from control & distribution panel.]
On control & distribution panel [Figure 3], connect DMM to BAT( ) (1, 2, or 3)
test point and PVR test point for battery string being installed.
