The safety grounding requirements are determined by the application and the connected instruments The Pointek CLS500 transmitter does not have any special requirements due to the galvanic separation between the measurement section and the loop section Depending on the DCS characteristics there are three possible grounding options e ifthe DCS measures the current through the loop compared to a common zero Volt point do not ground the negative side of the current loop because measurement inputs can be short circuited e ifthe DCS measures the current in the positive wire or connector the negative side of the current loop can be grounded e Ifthe DCS has galvanically separated inputs for each measurement channel the grounding method can be chosen as required In hazardous applications a Stahl type barrier is required and it is typically mounted on a DIN rail inside a customer supplied enclosure located in the non hazardous area Example 1 E a If no specific Ex conditions apply Pointek CLS500 be directly connected to the DCS The supply voltage however should remain within the limits set by the Pointek CLS500 Connecting a Pointek CLS500 to a DCS does not influence that equipment One of the connection cables can be grounded if desired o 36 22 2 13 lt lt 32
