Intended use

The EC-type examination certificate and the operating

instructions included in the delivery have to be read before

commissioning and the included notes must be observed on all

accounts.

Installation/Commissioning

These devices may only be installed, connected and operated

by trained and qualified staff. Qualified staff must have

knowledge of protection classes, directives and regulations

concerning electrical equipment designed for use in explosion

hazardous areas and if necessary, of the regulations applicable

to safety-related systems.Please verify that the classification

and the marking on the device comply with the actual application

conditions.

Comments

The use of Turck RFID extension cables (…/S2500) with

a length of up to 200 m to the RFID read/write head TN-

R42TC-EX connection to Turck fieldbus components (product

series BL20, BL67, TBEN-…) is possible under the following

prerequisite.- A sufficiently dimensioned power supply with

a stabilized output voltage of 24 VDC is used.- The voltage

drop on the cable is taken into account in such a manner

that the operating voltage range of the read/write head (10…

30 VDC) is not fallen short of at a current consumption of

approx. 75 mA (DC resistance cable loop: 116 Ω/km).- Installing

the cable taking into account avoiding interference (e.g.

separate installation of the RFID cable of supply cables of

motors; frequency converters etc.) and generally avoiding EMC

influence (see also installation handbook HF, d101582).- In

the explosion-hazardous area, the requirements with regard

to the EN 60079-14 standard are observed. The suitability of

all components for the customer-specific application must be

checked using tests
