Battery Connection
CAUTION: For safe operation and regulation compliance, DC overcurrent protection and means of
disconnect should be installed between the battery and inverter. In many cases individual battery units
will come with breakers, however overcurrent and disconnecting means should be added for banks of
multiple batteries. Please refer to the typical amperage in table below for required fuse or breaker size.
WARNING! All wiring design and install must be
performed by qualified personnel.

Please follow the below steps for battery connection:
1. Insert the ring connection end of the battery cable through the cable gland of the inverter.
2. Ensure the bottom (flat) side of the cable ring termination is fully seated on the inverter battery terminals.
3. Tighten the terminal nut
s to
a torque of 5 Nm (3.6ft
lbs)
. Make sure polarity at both the battery and the
inverter/charge
is
correctly
connected and ring terminals are tightly screwed
to
the
battery terminals.
WARNING: Shock Hazard
Arc and shock hazards are present! Do not touch uninsulated wires, and use caution when
making connections. Ensure all equipment is turned off, use proper safety equipment, and follow
best practices.
CAUTION!! Do not place anything between the inverter terminal and the battery cable ring
connector. Overheating and equipment damage can occur.
CAUTION!! Do not apply anti-oxidant substance on the terminals.
CAUTION!! Before making the final DC connection or powering on DC circuits ensure both
positive and negative cable runs are correctly connected throughout the system. Incorrect or loose
connections will damage equipment and pose electrical shock, arc, and fire risks.
