Maintenance
This unit is solid state and requires no constant adjustment or constant attention; however,
the following items should be checked:
Installation
Please note DC organizer is color
coded ensuring proper polarity
connections are made.
1. Choosing Conductors – Unlike AC
conductors, DC is sensitive to voltage drop,
the longer the round trip, the larger the
conductor needs to be. Follow the table
below for your installation. Like AC, use
only UL 1426 “Boat Cable” with a jacket
temperature rating of 105° C this is
commonly available at any marine supply
store. Do not use solid cable, speaker wire
or welding cable.
NOTE: Larger DC cables (generally 4 AWG and larger) require specialty tools to ensure proper
termination with ring terminals. DO NOT solder terminals of any size.

Verify LED status panel shows no fault condition and indicates
normal operation.
Condition of fuses/breakers check for as-new condition on
fuses (e.g. no discoloration or corrosion) and that a breaker
will manually trip and reset.
Check for proper ventilation and that no debris has collected
on the fan shroud or items have been improperly stored
around the ProNauticP.
Check battery terminal connections (both at battery and the
ProNauticP Charger) for corrosion, clean and reconnect
immediately upon signs of corrosion.
Per manufacturer’s instructions, check and top off batteries
with distilled water. Use of tap or bottled drinking water will
damage battery plates due to mineral content.
Check wire condition, overheating due to excessively long
or too small conductors will result in hardening of the insulation
or even burn marks at connections; If any of these signs
exist, immediately remedy the situation by installing the
proper conductors.
