3.6.2 Power cable wiring
Please charge all lithium batteries to 100% SOC before wiring! After charging,
make sure to disconnect the Battery Switch or MEH-B from the lithium battery,
and the lithium battery is in the OFF state!
Step 1: Remove the protective cover of the lithium battery (+) terminal.
Step 2: Connect the parallel cables L6(positive) between the lithium batteries. Torque requirement:
12N.m. Make sure the wiring is tight and firm.
Step 3: Connect the cable L1 between the fuse and the (+) terminal of the load or charger. Torque
requirement: 12N.m.Make sure the wiring is tight and firm.
Step 4: Connect the cable L2 between the fuse and the (+) terminal of the lithium battery. Torque
requirement: 12N.M.Make sure the wiring is tight and firm.
Step 5: Install the protective cover of the lithium battery (+) terminal.
Do not connect the (-) terminal first, otherwise it may cause a short circuit!
Step 6: Remove the protective cover of the lithium battery (-) terminal.
Step 7: Connect the parallel cables L7(negative) between the lithium batteries. Torque
requirement: 12N.M . Make sure the wiring is tight and firm.
Step 8: Connect the cable L3 between the (-) terminal of the load or charger and the (-) terminal of
lithium battery. Torque requirement: 12 N.M .Make sure the wiring is tight and firm.
Step 9: Install the protective cover of the lithium battery (-) terminal.
