SVARĪGI

Dr

ošības norādījumi šīs iekārtas pievienošanai un uzstādīš anai

Turpmākie drošības norādījumi attiecas uz visām ES dalībvalstīm. Tie ir
stingri jāievēro, lai nodrošinātu atbilstību Zemsprieguma direktīvai.
Turpmāk norādītais jāievēro arī valstīs, kas nav ES dalībvalstis, ja vien
šos norādījumus neaizstāj vietējie vai valsts standarti.

1.

Visi pieejamie iekšējie un ārējie zemējuma punkti ir atbilstoši jāiezemē.

2.

Pēc uzstādīšanas vai problēmu risināšanas visi drošības pārsegi un
drošības zemējuma savienojumi ir jāpievieno atpakaļ. Visiem zemējuma
savienojumiem vienmēr jābūt iezemētiem.

3.

Elektropadeves vadiem jāatbilst IEC227 vai IEC245 prasībām.

4.

Visai elektroinstalācijai jābūt piemērotai lietošanai apkārtējā
temperatūrā, kas pārsniedz 75°C.

5.

Visu izmantoto kabeļu blīvju iekšējiem izmēriem jābūt tādiem, lai
atbilstoši nostiprinātu kabeli.

6.

Lai nodrošinātu šīs iekārtas drošu darbību, savienojums ar
elektropadeves tīklu jāizveido, izmantojot slēdzi, kas kļūmes gadījumā
atvienos visas

ķēdes, kurās ir vadītāji. Slēdzī var būt iestrādāts arī

mehānisks pārtraucējslēdzis. Ja tāda nav, tad ir jāuzstāda cita veida
ierīce iekārtas atvienošanai no strāvas padeves un tā atbilstoši un skaidri
jāmarķē. Slēdžiem jāatbilst kādam vispāratzītam standartam, piemēram,
IEC947. Visai elektroin

stalācijai jāatbilst vietējiem standartiem.

7.

Vietās, kur iekārta vai tās pārsegi ir marķēti ar labajā
pusē norādīto simbolu, visticamāk, zem tiem ir bīstams
spriegums. Šos pārsegus drīkst noņemt tikai tad, ja
iekārta ir atvienota no strāvas padeves, – un šos darbus
drīkst veikt tikai atbilstoši apmācīti remontdarbu
darbinieki.

8.

Vietās, kur iekārta vai tās pārsegi ir marķēti ar labajā
pusē norādīto simbolu, apdraudējumu izraisa zem tiem
esošās karstās virsmas. Šos pārsegus drīkst noņemt tikai
atbilstoši apmācīti remontdarbu darbinieki, kad iekārta ir
atvienota no

strāvas padeves. Iespējams, dažas virsmas

arī pēc iekārtas atvienošanas paliks karstas.

9.

Ja iekārta vai pārsegi ir marķēti ar labajā pusē esošo
simbolu, skatiet operatora rokasgrāmatā ietvertos
norādījumus.

10. Visi

šajā izstrādājumā izmantotie grafiskie simboli atbilst

vienam vai vairākiem no šiem standartiem: EN61010-1,
IEC417 un ISO3864.

11. Ja

iekārtai vai uzlīmēm ir marķējums "Neatvērt, kamēr pieslēgta strāvai"

vai tamlīdzīga norāde, tas nozīmē, ka sprādzienbīstamā vidē ir
uzliesmošanas bīstamība. Šo iekārtu drīkst atvērt tikai tad, ja ir atvienota
strāva un ir nogaidīts iekārtas atdzišanai nepieciešamais laiks, kas
norādīts uzlīmē vai ekspluatācijas rokasgrāmatā, – un šos darbus drīkst
veikt tikai atbils

toši apmācīti remontdarbu darbinieki.
