Switch Relays Warning
Switch Relays Warning
Warning
The switch relays are rated at 1 Amp and have a voltage limit of 30 VDC and 0.3
Amp at a voltage limit of 125 VAC. It is dangerous to exceed these limitations
in a hazardous environment.
An electrical arc can occur when you connect or disconnect the relay wires
with field side power applied. This could cause an explosion in switch
installations in a hazardous location. Before proceeding, be sure that power
is removed or the area is not hazardous.
Statement 1061
Waarschuwing
De schakelrelais van 1 ampère hebben een spanningslimiet van 30 volt
gelijkstroom en 0,3 ampère bij een spanningslimiet van 125 volt wisselstroom
Het is riskant om deze beperkingen te overschrijden in een gevaarlijke
omgeving.
Een lichtboog kan optreden als u de relaisdraden aansluit of ontkoppelt
terwijl er stroom aan de kant van het alarmapparaat wordt toegepast. Dit kan
leiden tot een explosie bij schakelinstallaties op een gevaarlijke locatie. Zorg
dat de stroom is uitgeschakeld of het gebied niet gevaarlijk is voordat u
doorgaat.
Varoitus
Kytkinreleiden luokitus on 1 A jänniterajan ollessa 30 VDC ja 0,3 A
jänniterajan ollessa 125 VAC. Näiden rajojen ylittäminen on vaarallista
vaarallisessa ympäristössä.
Relejohtoja kytkettäessä tai irrotettaessa voi muodostua valokaari, jos
kenttäpuolen virta on päällä. Tämä voi aiheuttaa räjähdyksen, jos kytkin
asennetaan vaaralliseen paikkaan. Varmista ennen jatkamista, että virta on
katkaistu tai ettei alue ole vaarallinen.
