Conditions For The Application Of The Above Equipment In Zone 2 Hazardous Areas - Honeywell ST 3000 Bedienungsanleitung

This certificate applies to the following equipment:
ST 3000 Smart Pressure Transmitters, Series 100 and 900, Release 100 and 900, 4-20 mA,
DE, HART, and FOUNDATION
This equipment has no arcing or sparking parts and no ignition-capable hot surfaces, and therefore conforms to
Clause 6.3.1.3 of VDE 0165/2.91, IEC 60079-14, and EN 50021 for operation in Zone 2 hazardous areas
providing that the following conditions are observed. The equipment contains no intrinsically safe or energy-
limiting components. The listed equipment are 2-wire devices that receive their power and signal carrier from
the same 4-20 mA signal current or Fieldbus supply. In normal operation, the maximum current supply is 23
mA for £ 4-20 mA analog, DE or HART, and £ 260 mA for Fieldbus

Conditions for the application of the above equipment in Zone 2 hazardous areas:

1. The installation of this equipment in Zone 2 hazardous areas must comply with VDE specification 0165, IEC
60079-14, EN 50021 and/or valid national standards for installation and operation.
2. Before commissioning this equipment, it must be verified that the power supply voltage cannot exceed the 42
Vdc maximum for 4-20 mA analog, DE and HART equipment, and 32 Vdc for Fieldbus equipment.
3. The electronic assemblies in these units are non-repairable items and if faulty, must be replaced. The
electrical power supply must be switched off before any replacement and during any time that the wiring
terminations are being connected or disconnected.
4. The technical data supplied by the manufacturer must be adhered to.
