Installation
2. Fuse Selection - As illustrated in the diagram, each positive conductor from the charger to the
battery/battery bank must be fused. Choose a fuse that is 10 amps higher than the charger output (e.g.
60 amps, choose a fuse of 70 amps). These fuses come in a variety of sizes and types. When choosing
the proper fuse consider the connection to the DC cable (inline types for smaller amperages, stud and
nut connections for larger amperages) as well as the availability of replacements. Fuses and holders
are available through ProMariner or your local marine supply store.
3. Ground - This is extremely important and often overlooked. There is one common battery
ground with the positive battery connections on the ProNauticP. There is also a "Chassis Ground".
a. Battery Negative - As shown in the diagram, this is connected to a bus bar or terminal
stud (not included) that can handle, at a minimum the amperage of the charger output
(1260 = 60 amp minimum). This conductor shall be of equal size to the DC positive conductor
chosen above. The battery negative terminals are connected to this bus bar or terminal stud.
b. Bonding Stud A.K.A Chassis Ground - This stud is connected to the boats bonding system
as well as the bus bar or terminal stud mentioned above. This conductor is permitted to be
one size smaller than the DC positive conductor chosen above; in the case of a DC to the
case fault, this conductor is critical in carrying the fault current to trip the fuse or breaker,
the AC ground CAN NOT handle high DC amperages.
4. Empty Charger Banks - In the event of an empty charger bank there is no need to use a jumper as
done with traditional chargers. Simply leave the DC positive unloaded and the unit will perform correctly.
Remote Temperature Sensor Probe
Probe Connections:
Battery End (ring terminal) – Connect to the NEGATIVE terminal of the battery.
Charger End – Attach the "phone" style plug into the charger port labeled "Temp Sense".
Note: Once the temperature sensor is connected the charger will adjust its charge based on
the batteries temperature. This is known as thermal compensation, where the charger will cut
back if necessary to increase battery life. This is especially useful for AGM and GEL batteries
which are inherently temperature sensitive.
The ProNauticP comes standard with a
temperature probe that is plug and play. The
temperature probe must be connected while
the charger is powered down or before it is
connected to the breaker during installation.
For best performance, attach the probe to the
negative terminal of the "house" battery/bank.
