7 Impact and friction sparks

When used as category 1/2G instruments, the DPT-10-AF-R/A/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.

8 Material resistance

The DPT-10-AF-R/A/5/4****-*********-**must only be used in media against which the materials of thewetted parts are sufficiently resistant.

9 Ignition protection type flameproof enclosure Ex "d"

The terminals for connecting to the operating voltage, i.e. signal circuits, are integrated in theconnection compartment according to protection type flame-proof enclosure "d".

The thread gap between "Ex-d" connection compartment and cover is a flameproof gap.

The "Ex-d" connection compartment is provided with a M20 x 1.5 or ½-14 NPT thread for connectingto a certified "Conduit" system or for mounting an "Ex-d" cable gland certified according toEN 60079-1. Cable glands of simple construction may not be used. Please take note of section 13.1

and 13.2 of EN 60079-1. When connecting to a "Conduit" system, the corresponding seal must belocated directly on the "Ex-d" connection compartment.

Unused openings must be sealed according to EN 60079-1 paragraph 11.9.

A certified "Ex-d" cable gland is automatically supplied with the delivery. It is suitable for insertion ofarmoured or unarmoured cables depending on the ordered version. The instructions in the documentaccompanying the respective cable gland must be observed. The "Ex-d" cable gland must bescrewed tightly into the housing. The supplied cable gland is suitable for the housing temperaturerange mentioned in the DPT-10-AF-R/A/5/4****-*********-** specification. If a different cable gland isused, the separately certified cable gland or the temperature classes on the electronics determinesthe maximum permissible ambient temperature on the housing.

Before opening or in case the lid of the "Ex-d" connection compartment is open (e. g. duringconnection or service work), make sure that either the supply line is completely voltage free or noexplosive atmosphere is present.

The connection cable to the "Ex-d" connection compartment must be sufficiently secured againstdamage and laid in conformity with EN 60079-14.

The cover of the "Ex-d" connection compartment must be screwed in completely beforecommissioning and secured by screwing out the lid locking screw all the way to the stop.

The cover of the "Ex-d" connection compartment with the caution label "Do not… is present" and thecover of the "Ex-i" connection compartment without caution label must not be exchanged. The coversmust be mounted on the corresponding connection compartments.
