Räjähdysvaarallisten tilojen turvallisuusohjeita

•

USB väylää/liitintä EI saa käyttää räjähdysvaarallisissa tiloissa.

•

USB väylää/liitintä EI saa käyttää räjähdysvaarallisissa tiloissa. Käytettävä ehdottomasti ja ainoastaan hyväksyttyjä paristoja.

•

Käyttäjän vastuulla on laitteen käyttö räjähdysvaarallisissa tiloissa. Mittausovellus ja käyttöympäristö on ehdottomasti selvitettävä ennen käyttöä.



Käyttöön hyväksytyt paristot

nVision mittari on turvallinen määritellyissä räjähdysvaarallisissa tiloissa ainoastaan, kun käytetään seuraavia paristoja:

Approved Battery Type

Ta=

Marking

Rayovac Max Plus 815

-20 to 50° C

Ex ia IIB T4 Ga

Duracell MN1500

-20 to 45° C

Energizer E91, EN91

-20 to 50° C

Ex ia IIB T3 Ga

Duracell MN1500

Replace batteries with approved type in non-hazardous locations only

Monia muita paristotyyppejä on testattu, mutta on osoittautunut, etteivät ne täytä räjähdysvaarallisten tilojen vaatimuksia.

Energizer tuotemerkkiä valmistaa Energizer Holdings, Inc., ja Eveready Battery Company, Inc.
