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.
