Fault Protection
The power supply provides automatic protection for short-circuit overload, over-
voltage, and over-temperature situations.
In overload, over-temperature and short-circuit condition the power supply will shut
down. It will then automatically attempt to restart every 30 seconds until the fault is
removed.
For Reverse Battery protection an external battery fuse must be installed, refer to
Battery Fusing.
Fusing
Electronic Load Fuses
Each load output is protected by internal electronic fuse. Electronic fuses are low
maintenance and do not require replacement if a short circuit or over current
condition occurs. L3 to L14 are 10A, and L1 and L2 are 15A outputs. Their locations
are shown in Name and Function of Parts.
L1 is also set as a persistent load, allowing for this output to stay on if the battery
voltage falls below low voltage threshold 1 or if the Remote switch button via the
Trek
is pushed. This output will turn off if the battery discharges down to low voltage
threshold 2. Only light or temporary load MUST be added to L1, such as an electric
step.
Electronic fuses eliminate the requirement for the user changing fuses, when a
short occurs. The status of the output can be checked by LED indicators shown in
Name and Function of Parts. The output will return once the fault is removed.
Note:
The LED indicators have a narrow viewing window. One has to be directly above
them in order to view them.
Battery Fusing
Battery fusing with maximum rating of 40A must be added to the positive line of the
battery terminal and be installed as close as possible to the battery. See location
shown in Figure 3: DC Wiring Diagram for
BatteryPlus35SR
and
BatteryPlus35HA
Auxiliary (AX) Fusing
AX fusing must be added to the positive line of the AUX+ terminal. A fuse rating
not exceeding 30 Amps must be used. See location shown in Figure 3: DC Wiring
Diagram for
BatteryPlus35SR
and
BatteryPlus35HA
