USE CAUTION WHEN HANDLING THE
DDm MODULES
After a cell has been inserted into a
module at the factory, a loose fit could
develop because of recombination. The
cell could slip very easily from the
module if the module/cell is turned so
that the open end of the module is lower
than the closed end of the module.
Serious personal injury could result if the
cell slides unintentionally from the
module. Keep shipping/installation
retainer in place until modules are safely
positioned on the shelves.
BATTERY CELL INSTALLATION
DDm battery cells are designed for shipment
and use in steel modules.
1. BEFORE installing the cells, check the
voltages. The minimum acceptable cell
voltage is 2.05 vpc.
If a cell has a voltage below 2.05 vpc, call
your nearest EnerSys sales/service
representative for resolution, or call the
corporate office number listed on the back of
this manual and ask for EnerSys Integrated
Systems & Services.
2. Inspect each terminal for visual signs of
mechanical defects.
If terminals are acceptable:
3. Place the FIRST DDm module onto the
LOWEST EMPTY shelf, with the terminals
toward the front. See Figure 18.
