STEP 1: Disassemble the MC4 connector (female in the picture)
Bolt, metal terminal, gasket and nut from leftThe shape of the metal terminal is different between the male and female terminals, so please do not confuse it.
STEP 2: Crimp the metal terminals with a crimping tool.
Please choose the "crimping hole" that is suitable for the tool side. Insert the sheathed cable into the base of the copper wire that is seen. Hold strong. When the handle is open, the cable is crimped complete.
STEP 3: Attach the bolt
Deep until you hear a "click", push the metal terminal into the bolt.
Depending on the MC4 connector, the packaging may be difficult to reach out.Do not force it, check if the seal is properly contained. Tighten the area where your fingers do not spin and use the MC4 connector wrench for further tightening. Finished!!
