Do not short-circuit the main switch with other power supplies. The main switch
should be mounted on the boat, and the back plate of the main switch should
not be removed.
Only use the same batteries (same model, same capacity, same age and same
manufacturer) in series and/or in parallel. Variations in batteries will cause dam-
age.
Never reverse the polarity. Please pay more attention when connecting batteries
in series and/or in parallel configuration. Always double check by referring to
Figure 4-3.
