18. Place batteries 1 through 4 in positions shown in Figure 2.
19. Connect other end of patch cord [Figure 2] to BAT (+) connector of battery 4.

!
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).
