22. Connect battery string cable to battery string: plug
BAT1 (+)
(female) connec-
tor to
BAT (+)
connector from battery
1
and
BAT8 (
−
)
(male) connector to
BAT
(
−
)
connector from battery
8
.
23. Condition DMM to measure DC volts. Measure battery string voltage at gray
STR( )
connector (across clips) of battery string cable.
24. Does meter indicate battery string voltage of 49.5 V DC (absolute) or higher?
If
YES,
then proceed to Step
25.
If
NO,
then continue with Step
24.
25. Recheck battery connections for proper (positive to negative) sequence. Cor-
rect if necessary. If connections are correct, check individual battery voltage
(can be measured through cover). Any battery that indicates less than 6.2 V
DC should be replaced. If all batteries indicate less than 6.2 V DC, refresher
charge may be necessary. Refer to manufacturer's instructions for refresher
charge operation.

!
DANGER:
After connectors are mated, power bus will be "live" (i.e., have voltage on
it).
Connect together gray connectors on
STR( )
(1, 2, 3, or 4) battery string cable
and
STR( )
(1, 2, 3, or 4) cable from control & distribution panel.
27. Dress and secure cables to the top of the battery compartment as necessary
to keep them above batteries (in case of flood).
28.
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 4], connect DMM to
BAT( )
(1, 2, 3, or
4) test point and
PVR
test point for battery string being installed.
