1 GENERAL SAFETY INFORMATION
1.1 Scope of the document
These instructions are applicable only to the explosion-protection version of the TDR level transmitter. For all other data, use the Quick Start and other chapters of the Handbook. If you do not have these documents, please contact the nearest office or download them from the manufacturer's internet site.
INFORMATION!
The information in this chapter only contains the data applicable to explosion protection. The technical data for the non-Ex version in the Handbook shall be valid in its current version, provided that it is not rendered invalid or replaced by this chapter.
WARNING!
Installation, commissioning and maintenance may only be carried out by "Personnel trained in explosion protection".
1.2 Device description
This device is a 2-wire level transmitter that uses TDR (Time Domain Reflectometry) / Guided Radar technology. It measures the level, distance, volume and mass of liquids, liquid gases, pastes, powders, slurries and granular products. It is also suitable for the continuous and simultaneous measurement of level and interface of 2 liquids. Measurements are displayed via a DTM (device type manager) for remote communication or an optional integrated display screen with wizard-driven setup and online help functions.
OPTIFLEX 4300 C
The level transmitter is approved for use in potentially explosive atmospheres when equipped with the appropriate options.
Ex ia-approved devices can also be equipped with an external sensor to measure process temperature, pressure, etc.
1.3 Standards and approvals
DANGER!
In compliance with European Directive 94/9/EC (ATEX 100a), the ATEX version of the device described in these Supplementary Instructions conforms to European Standards EN 60079­0:2006, EN 60079-1:2007, EN 60079-11:2007, EN 60079-15:2005, EN 60079-26:2007, EN 61241­0:2006, EN 61241-1:2004 and EN 61241-11:2006. The Ex ia and Ex d [ia] versions are certified for use in hazardous areas by the KEMA Quality B.V. under KEMA 04ATEX1219 X.
WARNING!
Carefully read the ATEX approval certificate. Obey the boundary conditions.

2.1 Precautions
2.1.1 General notes
WARNING!
When you install the device, obey the conditions in the EC-Type Examination certificate. These conditions include:
The special conditions for safe use.
The Essential Health and Safety Requirements.
DANGER!
This installation must agree with EN 60079-14: Electrical installations in hazardous areas.
2.1.2 Electrostatic discharge
DANGER!
Risk of electrostatic discharge from the blue plastic sun cover, the conduit of the remote housing option and the optional plastic protective sheath for the single rod probe. Make sure that all personnel and equipment are correctly grounded.
INSTALLATION 2
Figure 2-1: ESD warning sticker (below the device nameplate)
1 Text: Plastic Parts 2 Text: Warning! Potential electrostatic hazard - see instructions
Take the necessary antistatic precautions if you:
handle,
install or
use
the device in potentially explosive atmospheres. Do not install in a location (near to ventilation systems, for example) where the electrostatic charge can increase.
