Connectors UIC 558 – Installation and Maintenance Instructions
Dangers and Security Measures
3. Dangers and Security Measures
3.1 Electrical Dangers
DANGER
The connectors contain components that carry voltage. Risk of electric shock!
Always observe the following safety regulations before beginning any work on electrical
constructions:
X
Disconnect
X
Ensure that it is not possible to reconnect unintentionally
X
Clearly mark your work area
X
Make sure that there is no voltage present
X
Earth and short circuit the installation
X
Insulate or cover adjacent energized parts
X
Only an electrically skilled person may determine if there is no voltage present
WARNING
Dirt, moisture, snow and ice in the interior of coupling receptacles or dummy receptacles contami-
nate the plug. The coupling of a contaminated plug to the coupling receptacle may lead to electric
shock, short circuit and damage to the connectors!
X
Always check if the interior of the receptacles is free from dirt, moisture, snow and ice before
inserting a plug into a coupling receptacle or a dummy receptacle.
X
Do not insert a plug into a receptacle when the latter is contaminated, moist or contaminated
with snow and ice.
X
Remove dirt, moisture, snow and ice without residues from the interior of receptacles and from
the plug.
X
Never couple a contaminated plug to the coupling receptacle.
3.2 Other Dangers
WARNING
Exclusively use the connectors for purposes as indicated in the specications and data sheets.
A wrong application can cause accidents and severe damages to persons.
X
The manufacturer doesn‘t take the responsibility for accidents which were caused by improper
use of the product.
X
We recommend the use of fault current safety systems in constructions with voltages higher
than safety extra-low voltage.
WARNING
The plugging and disconnecting of the connectors on-load can cause electric arcs. When explosive
substances or ignition sources of any kind are nearby, there is a risk of fire and explosion!
X
Never plug and disconnect the connectors on-load.
