3.
Disconnections in wiring
If the wiring is held and the connectors are pulled apart,
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, the soldering may be damaged, or the wiring may be
broken.
4.
High-pressure water entering connector
The connector is designed to make it difficult for water to enter
(drip-proof structure). If high-pressure water is sprayed directly on
the connector, water may enter the connector, depending on the
direction of the water jet. Be careful not to 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. If water gets into the connector, the pins will be
short-circuited by the water. If any water gets in, immediately dry
the connector or take other appropriate action before passing
electricity through it.
5.
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; there will be a 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. Remove the oil and water from the
compressed air completely before cleaning with compressed
air.

Disconnecting connectors
A. Hold the connectors when disconnecting.
•
For connectors held by a screw, loosen the screw fully,
then hold the male and female connectors in each hand
and pull apart.
•
For connectors which have a lock stopper, press down the
stopper with your thumb and pull the connectors apart.
★ Never pull with one hand.
