3.3.1 Choose DC Cable
It is suggested the battery pack be kept as close as possible to the inverter or DC load. The following
is a suggested wiring option for 1meter DC cable.
Please find the following minimum wire size, in case of DC cable longer than 1m, please increase
the cross section of cable to reduce the loss.

Performance of any product can be improved by thicker cable and shorter runs, so if in doubt, round
up and keep the length as short as possible.
For more wiring configurations for your specific system, please contact your distributor for more
information.
WARNING
The torque rating range for DC terminal is 9NM-12NM, and the suggested torque rating
is 9NM. Over torqueing may cause the bolt to break.
3.3.2 Fabrication of DC Cable
You can choose a DC cable manufacturing method according your battery connection ports.
a) Copper o-terminal
Manufacturing steps of battery connected power DC line:
Step 1: select the battery model, select the corresponding model wire, and peel off the front section
of the cable for 15mm;
Step 2: use the corresponding M8 or M6 o-terminal;
Step 3: insert the stripped wire into the o-terminal and press it tightly with the crimping fixture;
Step 4: select the box terminal crimping according to the model of circuit breaker between inverter
and battery;
Step 5: install the connecting wire according to the requirements of Chapter3.4.3 (reverse connection
of positive and negative wires is strictly prohibited).
b) Aviation terminal
