36658-EN-121026

Circuit of the indicating and adjustmentmodule: (spring contacts in the electronicscompartment; with double chamber housingversion also in the connection compartment)


Only for connection to the indicating and adjustmentmodule.With the double chamber housing version, theindicating and adjustment module may be mountedeither in the electronics compartment or in theconnection compartment.

The intrinsically supply and signal circuit is galvanically separated from parts that can be grounded.

The metallic parts of the DPT-10-AG-5/4****-*********-** are electrically connected with the earthterminals.

For applications requiring instruments of category 2G, the intrinsically safe power supply and signalcircuit can correspond to protection class ia or ib. For connection to a circuit with protection class ib,the ignition protection type identification is Ex ib IIC T6.

For applications requiring instruments of category 1G or category 1/2G, the intrinsically safe powersupply and signal circuit must correspond to protection class ia.

For applications requiring instruments of category 1G or 1/2G the DPT-10-AG-5/4****-*********-** ispreferably connected to appropriate equipment with galvanically isolated, intrinsically safe circuits.

7 Grounding

DPT-10-AG-5/4****-*********-**must be electrostatically (transition resistance ≤ 1 MΩ) grounded, e.g.via a ground connection terminal.

8 Impact and friction sparks

When used as category 1G or 1/2G instruments, the DPT-10-AG-5/4****-*********-** in aluminium/

titanium versions must be mounted in such a way that sparks from impact and friction betweenaluminium/titanium and steel (except stainless steel, if the presence of rust particles can beexcluded) cannot occur.
