3-4-6. Close to batteries
– Avoid excessive cable lengths but do not install
the Inverter in the same compartment as batteries.
Use the recommended wire lengths and sizes (see section 3-5).
Also do not mount the Inverter where it will be exposed to the
gases produced by the battery.
These gases are very corrosive and prolonged exposure also will
damage the Inverter.
3-5. Making DC Wiring Connections：
Follow this procedure to connect the battery cables to the DC input terminals
of the Inverter. Your cables should be as short as possible (Ideally,
less than 6 feet / 1.8 meters ) enough to handle the required current in
accordance with the electrical codes or regulations application. Cables are
not an adequate gauge (too narrow) or too long will decrease the inverter
performances such as poor surge capability and low input voltage warnings
frequently and shutdowns. UVP warning presents due to DC voltage drop
across the cables from the inverter to the batteries.
The longer or narrower the cables, the greater the voltage drop.
Increasing your DC cable size will help improve the situation.
Following cable recommendations for the best performance of inverter.
(Apply both 120V and 230V versions )
WARNING!
The installation of a fuse must be on positive cable.
Failure to place a fuse on
“+” cables running between
the inverter and battery may cause damage to the
inverter and will void warranty.
WARNING!
Shock Hazard. Before proceeding further, carefully
check that the Inverter is NOT connected to any
batteries, and that all wiring is disconnected from any
electrical sources. Do not connect the output terminals
of the Inverter to an incoming AC source.
