Operation

CAUTION
A reverse polarity connection (positive to negative) will
blow a fuse in the inverter and may permanently damage
the unit. Damage caused by a revers polarity connection
is not covered by warranty.
Determine Battery Capacity
Battery type and size affects the performance of the inverter and PFL. We
recommend that for optimum power as much battery capacity as possible is
used.
Connect the Battery Cables
To operate safely and effectively the inverter needs proper DC cables to be used
between the battery and battery connection posts on the PFL. Because the
inverter has low-voltage and high-current input, low resistance wiring between
the battery and the inverter is essential to deliver the maximum amount of usable
energy to the PFL
Cabling Guidelines
 Use 4AWG copper (90ºC insulation rating) as the smallest battery cable size.
This will minimise the voltage drop between the battery and the PFL. If the
cable causes an excessive voltage drop, the inverter will shutdown when
drawing higher currents because the inverter input drops below 10.5V.
 Keep all cables as short as possible, and ensure that each cable between the
battery and PFL is no longer than 6ft (1.8m).
 Ensure all wires and cables are terminated correctly, with appropriate sized
connectors.
 Do not use aluminium as it has about 1/3 more resistance than copper cable
of the same size. Additionally it is difficult to make good low-resistance
connections to aluminium wire

WARNING
Do not complete the next step if:
a) inflammable fumes are present, explosion or fire may results.
b) the PFL is connected to mains supply.
