(3) Precautions
q Align the mating tool W.FL-LP-IN or the
mating end of the tool W.FL2-LP-IN.OUT over
the plug end of the cable assembly.
w Firmly place the tool over the plug until it is
secured in the tool.
e Place the plug cable assembly (held in the
tool) over the corresponding receptacle.
r Assuring that the plug and receptacle are
aligned press-down perpendicular to the
mounting surface until both connectors are
fully mated.
t Remove the mating tool by carefully pulling it
up.Removal of the tool
q To disconnect connectors, insert the extraction side of insertion and extraction jig W.FL2-LP-IN.OUT and perform as
described in the diagram below.
Do not twist connectors excessively during mating / unmating.
