FOREWORD
C. Disconnections in wiring.
•
If the wiring is held and the connectors are pulled apart, or
components are lifted with a crane with the wiring still
connected, or a heavy object hits the wiring, the crimping
of the connector may separate, or the soldering may be
damaged, or the wiring may be broken.
D. High-pressure water entering connector.
•
The connector is designed to make it difficult for water to
enter (drip-proof structure), but if high-pressure water is
sprayed directly on the connector, water may enter the
connector, depending on the direction of the water jet.
•
Accordingly, take care not splash water over the
connector. The connector is designed to prevent water
from entering, but at the same time, if water does enter, it
is difficult for it to be drained.
•
Therefore, if water should get into the connector, the pins
will be short-circuited by the water, so if any water gets in,
immediately dry the connector or take other appropriate
action before passing electricity through it.
E. Oil or dirt stuck to connector.
•
If oil or grease are stuck to the connector and an oil film is
formed on the mating surface between the male and
female pins, the oil will not let the electricity pass, so there
will be defective contact. If there is oil or grease stuck to
the connector, wipe it off with a dry cloth or blow it dry
with compressed air and spray it with a contact restorer.
★ When wiping the mating portion of the connector, be
careful not to use excessive force or deform the pins.
★ If there is oil or water in the compressed air, the
contacts will become even dirtier, so completely
remove the oil and water from the compressed air
before cleaning with compressed air.
