Battery Circuit Requirements
Battery Positive Connection
The electronic panel operates on either a 12 VDC or 24 VDC electrical systems. The unswitched
battery positive connection to the panel is made at the weather proof connector. The panel
provides switched positive battery protected by a 15 Amp fuse (12 V or 24 V systems).
Protection for the unswitched battery positive circuit is dependent on specific equipment
configuration. The overload protection should not exceed 125% of the sum of all output currents
plus 5 Amps for the panel. Powering the panel through dedicated circuits with appropriate
overload protection reduces the possibility of panel damage.
Circuit breakers are preferred over in-line fuses for circuit protection. Over current protection
devices should ideally be located in a central location. If automatic reset circuit breakers are
used, consideration of the environment of the breaker is critical and may affect the trip point.
The trip point of some circuit breakers can be significantly reduced below the rated trip point if
the circuit breaker is exposed to high temperatures.
Warning!
Disconnecting the battery while the engine is running
may damage electrical components.
When using a battery disconnect switch, LOFA recommends using a
2 pole switch to disconnect both the battery and alternator output.
Battery Negative Connection (Grounding)
Warning!
Improper grounding can cause electrical noise, unreliable operation and may
damage the panel or other components. All ground connections must be free from
foreign materials, including paint, which may interfere with proper grounding.
A reliable ground must be provided for the panel.
LOFA recommends the ground connection be made directly to the battery
negative.
Grounding through frame members is not recommended.
All ground paths must be capable of carrying any likely fault currents.
Do not reverse the battery polarity. Attempting to crank the engine when the
polarity of the battery connections is reversed may damage the panel.
Note
A maximum of three ring terminals should be connected to a ground stud in order
to ensure integrity of the ground connection. The use of more than three terminals
can cause the connection to become loose.
Voltage Drop
If panel voltage drops below 6 volts for more than one tenth of a second, the panel may reset
causing the self-test to reactivate and the engine to shut down after 10 seconds. Resetting the
panel is equivalent to quickly turning the key switch to off and back to run without starting the
