Pozn\u00e1mka: Ak je vyhraden\u00fd uzem\u0148ovac\u00ed vodi\u010d ulo\u017een\u00fd v tom istom ochrannom potrub\u00ed ako f\u00e1zov\u00fd vodi\u010d, mal by ma\u0165 rovnak\u00fa \u00farove\u0148 izol\u00e1cie ako f\u00e1zov\u00fd vodi\u010d. <\/p>\n\n\n\n
2) Pri svietidl\u00e1ch vo v\u00fdbu\u0161nom prostred\u00ed z\u00f3ny 2 a z\u00f3ny 22 mo\u017eno ako uzem\u0148ovac\u00ed vodi\u010d pou\u017ei\u0165 spo\u013eahliv\u00fd kovov\u00fd potrubn\u00fd syst\u00e9m elektrick\u00e9ho pripojenia, ale nemo\u017eno pou\u017ei\u0165 potrubia na prepravu v\u00fdbu\u0161n\u00fdch nebezpe\u010dn\u00fdch l\u00e1tok. <\/p>\n\n\n\n
3) Vyhraden\u00e9 uzem\u0148ovacie vodi\u010de pre elektrick\u00e9 zariadenia a svietidl\u00e1 by mali by\u0165 samostatne pripojen\u00e9 k hlavn\u00e9mu uzem\u0148ova\u010du (sieti) a pracovn\u00fd nulov\u00fd vodi\u010d v elektrickom obvode by sa nemal pou\u017e\u00edva\u0165 ako ochrann\u00fd uzem\u0148ovac\u00ed vodi\u010d. <\/p>\n\n\n\n
4) Na spojenie medzi elektrick\u00fdm zariaden\u00edm v prostred\u00ed s nebezpe\u010denstvom v\u00fdbuchu a uzem\u0148ovac\u00edm vodi\u010dom by sa mal prednostne pou\u017ei\u0165 viacvl\u00e1knov\u00fd pru\u017en\u00fd dr\u00f4t s minim\u00e1lnym prierezom meden\u00e9ho dr\u00f4tu najmenej 4 mm\u00b2. Na \u010dastiach n\u00e1chyln\u00fdch na mechanick\u00e9 po\u0161kodenie by sa mali nain\u0161talova\u0165 ochrann\u00e9 trubice. <\/p>\n\n\n\n
5) Ak s\u00fa do elektrick\u00e9ho zariadenia zaveden\u00e9 pancierov\u00e9 k\u00e1ble, uzem\u0148ovac\u00ed vodi\u010d by mal by\u0165 pripojen\u00fd k uzem\u0148ovacej skrutke vo vn\u00fatri zariadenia; oce\u013eov\u00e1 p\u00e1ska a kovov\u00fd kryt by mali by\u0165 pripojen\u00e9 k vonkaj\u0161ej uzem\u0148ovacej skrutke zariadenia. <\/p>\n\n\n\n
6) Skrutky pou\u017e\u00edvan\u00e9 na uzemnenie alebo nulov\u00e9 spojenie v prostred\u00ed s nebezpe\u010denstvom v\u00fdbuchu by mali ma\u0165 zariadenia proti uvo\u013eneniu; pred utiahnut\u00edm uzem\u0148ovacieho vodi\u010da by sa mali uzem\u0148ovacie svorky a spojovacie prvky natrie\u0165 mazivom z energetickej zmesi. <\/p>\n\n\n\n
Existuje mnoho po\u017eiadaviek na uzemnenie elektrick\u00fdch zariaden\u00ed v prostred\u00ed s nebezpe\u010denstvom v\u00fdbuchu. V procese n\u00e1vrhu a in\u0161tal\u00e1cie by sa okrem splnenia uveden\u00fdch po\u017eiadaviek mali dodr\u017eiava\u0165 aj pr\u00edslu\u0161n\u00e9 normy.<\/p>","protected":false},"excerpt":{"rendered":"
