DANGER:
When connecting batteries together, be careful not to connect together
the positive and negative terminals of the same battery.
Connect batteries together by plugging
BAT (
−
)
connector from one battery
into
BAT (+)
connector from next battery [Figure 2]. Repeat for remaining bat-
teries in battery string.
21. 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
.
22. Condition DMM to measure DC volts. Measure battery string voltage at gray
STR( )
connector (across clips) of battery string cable.
23. 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.
24. 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.
25. Connect together gray connectors on
STR( )
(1 or 2) battery string cable and
STR( )
(1 or 2) cable from the power shelf. Verify battery cable
J140
is plugged
in
P140
on the side of the power shelf.
26. Dress and secure cables to the top of the battery compartment as necessary
to keep them above batteries (in case of flood).
