● Do not connect loads between the inverter and the battery.
● Ensure that the battery cables are connected to the battery terminals of the
inverter. If a battery cable is connected incorrectly to the DC input terminal of
the inverter, the inverter may be damaged or even a re may occur.
● The battery cables must be connected correctly. That is, the positive and
negative terminals of the battery connect to the positive and negative battery
terminals of the inverter, respectively. Otherwise, the inverter may be damaged
or even a re may occur.
If power cables are not installed or routed as required during the installation of
the inverter and the battery, the positive or negative terminal of the battery will
be short-circuited to ground. In this case, an AC or DC short circuit may occur and
damage the inverter. The resulting device damage is not covered by the product
warranty.
Procedure
Step 1 Assemble the positive and negative connectors by referring to 5.5 Connecting DC
Input Power Cables.
● The battery voltage will result in serious injury. Use dedicated insulation tools
to connect cables.
● Ensure that cables are connected correctly between the terminals of the battery
and the battery switch, and between the battery switch and the battery
terminals of the inverter.
Cables with high rigidity, such as armored cables, are not recommended as battery
cables, because poor contact may be caused by the bending of the cables.
Step 2 Insert the positive and negative connectors into corresponding battery terminals
on the inverter.
After the positive and negative connectors snap into place, pull the battery cables
back to ensure that they are connected securely.
