Perform the 45 N (10 lb) pull test on each wire. Each terminal and each connector should easily withstand 45 N (10 lb) of tension and each wire should remain in the connector body. This test checks whether the wire was properly crimped in the terminal and whether the terminal was properly inserted into the connector. Expected Result:Each terminal and each connector easily withstands 45 N (10 lb) of pull and each wire remains in the connector body.Results:
OK - All terminals pass the pull test. Proceed to Test Step 5.
Not OK - A wire has been pulled from a terminal or a terminal has been pulled from the connector.Repair: Use the 1U-5804 Crimp Tool to replace the terminal. Replace damaged connectors, as required.
