WARNING
• InthecasewheretheenclosureofthePressure
Transmitterismadeofaluminium,ifitismounted
inanareawheretheuseofcategory1G
apparatusisrequired,itmustbeinstalledsuch,
thatevenintheeventofrareincidents,ignition
sourcesduetoimpactandfrictionsparksare
excluded.
• Electrostaticchargemaycauseanexplosion
hazard.Avoidanyactionsthatcausethe
generationofelectrostaticcharge,suchasrubbing
withadryclothoncoatingfaceoftheproduct.
• InthecasewheretheenclosureofthePressure
Transmitterismadeofaluminum,ifitismountedin
anareawheretheuseofcategory2Dapparatusis

riskfromelectrostaticdischargesandpropagating
brushdischargescausedbyrapidowofdustis
avoided.
• TosatisfyIP66orIP67,applywaterproofglandsto
theelectricalconnectionport.
• Whenthelightningprotectoroptionisspecied,
theapparatusisnotcapableofwithstandingthe
500VinsulationtestrequiredbyEN60079-11.
 Thismustbetakenintoaccountwheninstalling
