Reverse polarity
NOTE: The unit will operate optimally below 55°C with good airflow. At higher
temperatures the unit will de-rate output current.
NOTE: Appropriate connections must be made to the wires with a continuous current
rating of at least 25A for the LFP1225(LV) or 40A for the LFP1240(LV). Failure to do so
may cause damage to the unit and vehicle.
2 INSTALLATION
Mount the unit to a flat surface close to the auxil-
iary battery and away from any heat sources. The
LFP1225(LV)/LFP1240(LV) has 6 wires and is should
be installed as described over the following pages.
2.1
RED wire - Input Source Positive
The RED wire should be connected to the positive input
from the source - this can be either from a vehicle’s
starter battery or from a solar panel.
Appropriate size fuses should be used as per the
specifications table on page 2.
