6.7. Charging the Batteries
All DPSI systems switch on the batteries positive pole, i.e. both
batteries are, if connected to the DPSI RV, connected together by the
negative (ground) pole. Simultaneous charging is not always possible
because most chargers which possess several charging outputs,
measure using the negative line but join the positive wires. Separate
charging of the batteries, if still connected to the DPSI is possible
anytime!
If charging of the battery should be possible, even if it is connected to
the DPSI, a second cable has to be soldered to the battery, which
serves as a charging cable. This cable runs in parallel to the
connection cable to the DPSI.
If in doubt, it is reasonable and safer to detach the batteries from the
DPSI for charging. Pull the plug in zigzag movements from the holding
clamps of the DPSI (see photo).
Hint:
It is possible to charge the battery (e.g. via an additional charging cable which is
soldered on) if it is attached to a DPSI. Here, only one battery must be charged
rather than both at once. Please observe correct polarity always!
