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.
