Calculating Cable Sizes - Motomaster ELIMINATOR 299-5299-0 Owner's Manual

The Mobile Digital Power Inverter must only be installed in a location that is:
Dry Do not allow water or other liquids to drop or splash on it.
Cool Ambient air temperature should be between 32 °F and 105 °F (0°C
and 40°C)—the cooler the better within this range.
Ventilated Allow at least 3"(7.5cm) of clearance around the inverter for air
flow.Ensure that the ventilated openings on the DC end and on the
AC end of the unit are not obstructed.
Safe Do not install the inverter in the same compartment as batteries or
in any compartment capable of storing flammable liquids like
gasoline.
Close to Do not use excessive DC cable lengths:they increase wire resistance
battery and reduce input power.Longer AC wires are preferable to longer
DC wires:wire resistance(and therefore voltage drop)is less and
the cost is lower.
Protected from Do not mount the inverter where it will be exposed to gases
battery gases producted by batteries.Battery gases are corrosive,and prolonged
exposure to battery gases will damage the inverter.
Calculating Cable Sizes
To operate safely and effectively, the Mobile Digital Power Inverter needs proper
cables and fuses. Because the Mobile Digital Power Inverter has low‐voltage and
high‐current input, it is essential that you use low‐resistance wiring between the
battery and the inverter to deliver the maximum amount of usable energy to your
load.
For safe and efficient operation, you will need to calculate cable sizes for your:
• DC input cables from the battery to inverter (one way).
WARNING:Fire hazard
Never use a DC cable longer than 5'(1.5m).A cable longer than 5'(1.5m)
Can potentially generate enough heat to start a fire or result in poor
Inverter performance.
