6. Do not install in engine compartment – please install in a well ventilated area.
7. This inverter is not tested for use with medical devices.
IMPORTANT WIRING INFORMATION
Substantial power loss and reduced battery operating time results from inverters installed with wires
that are not sized correctly based on the length and the current required to be carried. Current flowing
through a wire produces voltage drop along its length due to the resistance of the wire and due to
the value of the current carried through it. The resistance of the wire is inversely proportional to the
cross-sectional area of the wire (designated in mm 2 or AWG) and directly proportional to its length i.e.
thinner and longer wire has higher resistance and hence, produces higher voltage drop. Similarly, thicker
and shorter wire has lower resistance and hence, produces lower voltage drop. Hence, symptoms of
low DC input voltage / battery power can result from wires that are either excessively long or have an
insufficient cross-sectional area (designated in mm 2 or AWG). The wires should be sized based on the
maximum current they are required to carry and the distance between the battery and the inverter to
limit the voltage drop to 2% to 5%.
Wires are rated based on its insulation, temperature and operating environment. Please ensure that the
wire insulation is of the appropriate type for the operating environment.
The installer/operator should be especially aware of the requirements to maintain secure, tight, water-
resistant electrical connections and to provide for strain relief for DC wires and appliance wiring.
