Connectors UIC 558 – Installation and Maintenance Instructions
Plugging Procedure
NOTICE
Inappropriate handling when plugging or disconnecting may damage the connectors. The functional safety of
the connectors is no longer guaranteed when parts are damaged.
X
Make sure that the slots (1) and guideways (2) of receptacle and plug always interlock when plugging
(
Fig. 19
)!
X
Take care that plug and receptacle do not tilt and that they are plugged without force.
X
Make sure before the plugging procedure that plug and receptacle as well as the hinged lid of the recepta-
cle are not contaminated. Remove any existing dirt.
X
Make sure that when not mated,
-
the plug is always inserted into a dummy receptacle,
-
the hinged lid of receptacles is closed according to its intended use.
X
Open the hinged lid of the receptacle by an angle of at least 110° but not more than 130° (refer to
Fig. 20
).
Overstretching of the hinged lid may shorten the operational life span of the torsion spring and may dam-
age the hinge mechanism.
X
Always close the hinged lid by hand, don’t let it slam!

In case of a very low or very high ambi-
ent temperature which approximates the
limits of the allowable operating tem-
perature range specified in our catalogue

”,
-
a higher effort may be needed for the
plugging and unplugging and
-
the operational life span of plug and
coupling receptacle may thus be re-
duced due to increased wear and tear.
