DC Plug Polarity
The charging cables are connected to the DC output of the charger with the red cable to the
positive bussbar, and the black cable to the negative bussbar. The red cable is terminated into
the “+” side of the battery connector, and the black cable is terminated into the “-“side of the
connector. The output polarity of the charger must be observed when connecting to the battery
(read warning above). Improper connection will open the DC fuses in the power modules.
GLOSSARY
Wi-iQ
®
Device
This unit, permanently mounted on the battery, ensures that certain battery parameters can be
sent to the charger for the purposes of optimizing the charge and monitoring the charging and
discharging characteristics.
Charging Profile
The charging profile defines the rate of current charge over time. The charger adapts to the
battery’s age and level of discharge. Controlling the overcharge coefficient, whatever the
battery’s discharge level, reduces the amount of electricity consumed.
Thin Plate Pure Lead (TPPL)
This is an advanced lead acid battery design used in NexSys
®
batteries. TPPL technology
provides longer service life, higher power density, longer shelf life and fast recharge capabilities.
Cold Storage Profile
This is a charging profile that allows the configuration of the charger for use with batteries in cold
storage application. The profile is an IEI (constant current, constant voltage, constant current)
type with a number of user configurable parameters.
Gel-Bloc Profile
This charging profile is an I-E-I (constant current, constant voltage, constant current) charging
profile designed for Gelled Electrolyte type sealed lead acid batteries.
IONIC™ Profile
The IONIC™ charging profile diagnoses the battery throughout the recharge and adjusts the
charging profile to effectively charge the battery. The intelligent diagnostic sampling provides
more rapid optimized charging of flooded cell batteries subject to very high demands. The short
current pulses stimulate gas formation in the active material, causing sulfuric acid to be
distributed outside the plates and balances out differences in density, homogenizing the
electrolyte across the surface of the plates.
NXBLOC Profile
This charging profile allows charging of NexSys TPPL bloc batteries at rates of 0.2 to 0.7 C6.
NXSTND Profile
This charging profile allows charging of NexSys 2V batteries at rates of 0.20 to 0.25 C
