Wiring your ProMar1 DS Series Charger Correctly
Simply choose the illustration that has the same number of charger outputs as your
ProMar1 DS Series Battery Charger and matches your application. Then wire exactly as shown
for proper charger operation.
Incorrect wiring can result in reverse polarity. In the event this happens, the ProMar1 DS
Series has been designed to not fail as a result. Reverse polarity will cause the charger to "internally
disconnect" and provide "no output" until the (reverse polarity) is corrected. A reverse polarity is
caused by putting the "Red" + positive lead on a - negative battery terminal and/or a “Black”
- negative lead on a + positive battery terminal. In the event of miswired battery(s), the charger
will illuminate a red Battery Trouble Status LED for the specific battery requiring attention.
When connecting each jacketed battery charger cable, make sure it is connected
to only
one 12 VDC battery
and observe the polarity and color of all connections:
Red Wire = + (Positive) Battery connection
Black Wire = - (Negative) Battery connection
The black wire can never be connected to a terminal with red wires. Only black.
Important: The pair of red and black wires in 1 cable jacket MUST GO TO THE SAME 12 VDC battery.
Each charger cable
must
be connected to 1 battery,
just as shown. Observe
black to (-) and red to (+).
Do this for each battery.

Installation
When connecting to an engine start battery, connect the battery bank cable 1 that is LABELED:
"Use on Engine Battery
1
".
Note: ProMar1 DS Series Waterproof Marine Battery Chargers are designed for any combination
of group 24, 27, 29, 30 and 31 batteries. Each battery charger DC output cable must be connected
to one (1) 12 Volt DC battery (even if batteries are configured for 24 Volt DC or 36 Volt DC trolling
motor or system applications). Most specifically you do not have to remove series or parallel jumper
cables to use your ProMar1 DS Series Charger. See typical wiring diagrams for these systems in the
installation section of this manual.
Note: The ProMar1 DS Series must be connected to batteries to operate. It will not operate
as a 12 volt power supply.
If there are more charger outputs than batteries, then a set of leads can be taped off
until needed for an additional battery. Please note the Fault LED for taped / not used output
will illuminate red until it is connected to a healthy battery.
