Final Assembly Check Procedure

1. For future identification of all cells, number individual
cells in sequence, beginning with number one (1) at the
positive end of the battery. The last cell of the
battery is located at the negative output terminal.
2. Read and record the voltages of the individual cells
to assure that they are connected properly. The total bat-
tery voltage should be approximately equal to the num-
ber of cells connected in series multiplied by the meas-
ured voltage of one cell. If the measurement is less,
recheck the connections for proper polarity. Verify that
all cell and battery connections have been properly
torqued.
3. Measure and record the intercell connection resistance
using a micro-ohms meter. This helps determine the
adequacy of initial connections and can be used as a ref-
erence for future maintenance requirements.Refer to the
recording forms in Appendix A of this manual. Review
the records of each connection and detail resistance
measurements. Clean, remake, and remeasure any con-
nection that has a resistance
measurement greater than 10% of the average of all the
same type connections (i.e. intercell, intermodule, etc.).
4. Battery performance is based on the output at the
battery terminals. Therefore, the shortest electrical
connection between the battery system and the
operating equipment results in maximum total
system performance.
Select cable size based on current carrying capability and
voltage drop.
Cable size should not provide a greater voltage drop
between the battery system and operating equipment than
specified. Excessive voltage drop in cables will reduce the
desired reserve time and power from the battery system.

Safety Shield Assembly

1. All Safety Shield Brackets should already be installed at
this time. Refer to Cell Installation Section for bracket
installation.
2. Safety Shields are designed with a "keyhole" type
attachment
3 One shield will cover two modules. Hang the first shield
on the top brackets through the large part of the keyhole.
At the same time aligning the cutout at the bottom of the
shield with the second set of brackets. After all shields
are in place tighten, but do not torque hardware.

Top Protection Shield Installation

For side terminal assembly, attach top protective cover
to highest front shield.
For top terminal assembly, cut protective cover to fit
between the terminals and then attach to front shield.
SYSTEM OPERATIONS
Charger Voltage
These batteries are designed for continuous float applica-
tions. When setting the float voltage on the charger, the
system should be set to float at the nominal cell float voltage
times the number of cells per string. The charger must be
able to maintain the system voltage within ± 0.5% of the
desired level at all times. The desired float voltage varies
with temperature according to the table in the next column.
