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 same time ( The maximum charging current of 15 A of SEC-1215A
/ SEC-2415A and 30 A of SEC-1230A 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 con-
nected 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
terminals of 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
