oppoverbøyde kabelsko. Disse avslutningene skal ha riktig størrelse i forhold
til ledningene, og skal klemme sammen både isolasjonen og lederen.
Aviso Quando forem requeridas montagens de instalação eléctrica de cabo
torcido, use terminações de cabo aprovadas, tais como, terminações de cabo
em circuito fechado e planas com terminais de orelha voltados para cima.
Estas terminações de cabo deverão ser do tamanho apropriado para os
respectivos cabos, e deverão prender simultaneamente o isolamento e o fio
condutor.
¡Atención! Cuando se necesite hilo trenzado, utilizar terminales para cables
homologados, tales como las de tipo "bucle cerrado" o "espada", con las
lengüetas de conexión vueltas hacia arriba. Estos terminales deberán ser del
tamaño apropiado para los cables que se utilicen, y tendrán que sujetar tanto
el aislante como el conductor.
Varning! När flertrådiga ledningar krävs måste godkända ledningskontakter
användas, t.ex. kabelsko av sluten eller öppen typ med uppåtvänd tapp.
Storleken på dessa kontakter måste vara avpassad till ledningarna och måste
kunna hålla både isoleringen och ledaren fastklämda.

Distance Limitations for Signaling
Improperly installed wires can emit radio interference. In addition, the potential for damage
from lightning strikes increases if wires exceed recommended distances or if wires pass
between buildings. The electromagnetic pulse (EMP) caused by lightning can damage
unshielded conductors and destroy electronic devices. If your site has previously
experienced such problems, you might want to consult experts in electrical surge
suppression and shielding.
Radio Frequency Interference
You can reduce or eliminate the emission of radio frequency interference (RFI) from your
site wiring by using twisted-pair cable with a good distribution of grounding conductors.
If you must exceed the recommended distances, use a high-quality twisted-pair cable
with one ground conductor for each data signal when applicable.
Electromagnetic Compatibility
If your site is susceptible to problems with electromagnetic compatibility (EMC),
particularly from lightning or radio transmitters, you might want to seek expert advice.
