The inverter can be operated in any position, however, if it is to be mounted on a wall, mount it
horizontally (fig 3a) so that indicators, switches, outlets and terminal blocks located on the front panel
are visible and accessible. Do not mount on wall in positions shown in figs. 3(b) & 3(c).

CAUTION
The power inverter must be connected only to batteries with a nominal output voltage of 12 V. The
unit will not operate from a 6 Volt battery, and will sustain permanent damage if connected to a 24 V
battery.
CAUTION
Loose connectors may cause overheated wires and melted insulation. Check to make sure you have not
reversed the polarity. reverse polarity connection will result in a blown fuse and may cause permanent
damage to the inverter. Damage due to reverse polarity is not covered by warranty.
CONNECTING TO A DC POWER SOURCE
Please ensure that the DC side wires and external fuses are selected as given below.
Note that an external fuse is required to protect the battery wires from short circuit. A battery is an
unlimited source of current and can deliver extremely high (up to 10,000 A of current) into a short circuit
that will melt the wires and cause fire hazard.
Current limiting fuse with Ampere Interrupting Capacity (AIC) of 10000 A or more or Class T fuse is,
therefore, recommended.
