Use in areas requiring ignition protection

Pos: 5 /Ex-technische Sicherheitshinweise/Temperatur/TTR200/Allgemeine Sicherheitshinweise zum Ex-Schutz, TTR200 @ 15\mod_1195564087109_3101.doc @ 141669
Special regulations must be observed in explosion-protection zones for the auxiliary power
connection, signal inputs/outputs and ground connection. Information on ignition protection in
the separate chapters must be observed.
Notice - Potential damage to parts!
All parts must be installed in accordance with manufacturer information and relevant
standards and regulations.
Startup and operation must comply with EN 600790-14 (Installation of equipment in potentially
explosive atmospheres).
2.1

Approvals

The approvals for use of the TTR200 temperature transmitter in explosion-protection areas can
be found in the section "Explosion-protection relevant information" in the operating instructions.
2.2

Level of protection

The adapters for the model TTR200 temperature transmitter meet the IP 20 level of protection
in accordance with IEC 60529:1989.
2.3

Electrostatic charging

When using the transmitter in zone 0, make sure you prevent electrostatic charging of the
TTR200-E1H temperature transmitter (observe warnings on equipment).
2.4

Grounding

If for functional reasons, the intrinsically safe circuit has to be grounded by connection to the
equipotential bonding system, it may only be grounded at a single location.
2.5

Interconnection

If transmitters are operated in an intrinsically safe circuit, proof that the interconnection is
intrinsically safe must by provided in accordance with DIN VDE 0165/Part1 (EN 60079-25/2004
and IEC 60079-25/2003). In general, intrinsically safe circuits require proof of interconnection.
2.6

Configuration

The TTR200-E1 temperature transmitters can be installed in the explosion-protection area in
compliance with the proof of interconnection and directly in the explosion-protection area using
approved handheld HART terminals as well as by coupling an ignition-proof modem to the
circuit outside the explosion-protection area.
2.7

Explosion-protection relevant information

For additional information, refer to the section "Explosion-protection relevant information" or the
data sheet.
