Connecting the batteries or other DC loads
The output has a common Negative(-) terminal and 3 Positive terminals for connection of 3
banks of batteries. Each Positive connector has it‘s own internal isolating diode which works as
a battery isolator. If more than one bank of batteries is connected, these will be charged at the
sametime (The maximum charging current of 15 A of SEC-1215E / SEC 2415E and 30 A of
SEC-1230E will be shared among the connected banks of the batteries depending upon their
discharged states) as long as the AC power is available to the charger. In case the AC power fails
or if there is no output from the charger, the isolating diodes will prevent charging/discharging
among the batteries connected to the banks.
CAUTION! When a bank consisting of more than one battery in parallel is to be charged,
make sure that their negatives are connected to the common negative terminal of the charger and
their positives are connected to the same positive terminal of the charger. For example, when
charging a bank consisting of 3 batteries connected in parallel, their 3 negative terminals should be
connected to the common negative terminal of the charger and all their 3 positive terminals should
be connected to the same (one of the 3) positive terminals of the charger. Alternatively, the negative
terminals of the 3 batteries should first be shorted and then connected to the common negative
terminal of the charger and similarly, the 3 positive terminals of the battery should first be shorted
and then connected to one of the 3 positive terminal sof the charger.
When connecting a single battery or other DC load, it can be connected to the common
negative and any one of the 3 positive terminals.
