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!
