OLULINE TEAVE 

Juhtmestiku ja seadme paigaldamisega seotud ohutusjuhised 

Alljärgnevad ohutusjuhised rakenduvad eriti kõigi Euroopa Liidu 
liikmesriikide suhtes. Antud juhiseid tuleb täpselt järgida, et kindlustada 
vastavus madalpinge direktiiviga. Euroopa Liitu mittekuuluvad riigid 
peavad samuti alljärgnevaid juhiseid järgima, va juhul, kui on olemas 
vastavad kohalikud riiklikud standardid. 

1.  Ettenähtud maanduspunktide, nii sisemiste kui väliste jaoks tuleb 

tagada nõuetekohased maaühendused. 

2.  Pärast paigaldamist või rikketuvastust tuleb kõik turvaümbrised ja 

turvamaandused uuesti oma kohale seada. Kõigis olukordades tuleb 
säilitada kõigi maandusklemmide terviklikkus. 

3.  Toitejuhtmed peavad vastama IEC227 või IEC245 nõuetele. 

4.  Kogu juhtmestik peab sobima kasutamiseks üle 75°C õhutemperatuuri 

juures. 

5.  Kõik juhtmetihendid peavad sisemõõtmete poolest tagama 

nõuetekohased kaabliühendused. 

6.  Seadme ohutu töötamise tagamiseks peab ühendus toiteallikaga 

toimuma vaid läbi automaatkorgi, mis veaolukorras lülitab välja kõik 
voolukandjad. Automaatkorgil võib olla ka mehhaaniliselt reguleeritav 
lahklüliti. Vastasel juhul peab seadme toiteallikast lahtiühendamiseks 
olema teine ja selgelt osutatud moodus. Automaatkorgid või -lülitid 
peavad vastama tunnustatud standarditele nagu nt IEC947. Kogu 
juhtmestik peab vastama kohalikele standarditele. 

7.  Seadmel või ümbristel asuv paremale osutav sümbol 

tähistab selle all leiduvat ohtlikku pinget. Selliste 
sümbolitega ümbriseid võib eemaldada vaid juhul, kui 
seade on toiteallikast lahti ühendatud ning ka siis ainult 
vastavate oskustega spetsialisti poolt. 

8.  Seadmele või ümbristele märgitud paremale osutava 

sümboli all valitseb kuumadest pindadest tulenev oht. 
Nimetatud sümbolitega ümbriseid võib eemaldada vaid 
vastavate oskustega spetsialist, kui seade on 
toiteallikast lahti ühendatud. Teatud pinnad võivad 
puudutamise jaoks liiga kuumad olla. 

9.  Seadmel või ümbristel leiduva paremale osutava 

sümboli korral vt juhiste jaoks Toimimisjuhendit. 

10.  Kõik selle toote juures kasutatavad graafilised sümbolid 

lähtuvad ühest või enamast järgmistest standarditest: 
EN61010-1, IEC417 ja ISO3864. 

11.  Kui seadmele või siltidele on kirjutatud "Ärge avage voolutarbimine 

korral" vms, valitseb plahvatusohtlikus keskkonnas süttimise oht. 
Seadet võib avada ainult siis, kui toide on lahti ühendatud ning seadmel 
on võimaldatud sildil või kasutusjuhendis osutatud aja jooksul maha 
jahtuda -- ning ka sellisel juhul ainult vastavate oskustega spetsialisti 
poolt.
