1 GENERAL SAFETY INFORMATION
1.1 Scope of the document
These instructions are applicable only to the explosion-protection version of the radar level
transmitter. For all other data, use the Quick Start and 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 these supplementary instructions 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 these supplementary
instructions.
WARNING!
Installation, commissioning and maintenance may only be carried out by "Personnel trained in
explosion protection".
1.2 Device description
OPTIWAVE 6300 C
This device is a 2-wire level transmitter that uses FMCW (Frequency-Modulated Continuous
Wave) radar technology. It measures level, volume, distance to surface, and reflectivity of solid
particles, granulates and powders.It is suitable for installation on storage tanks and silos.
Measurements are displayed via a DTM (device type manager) for remote communication or on
an optional integrated display screen with wizard-driven setup and online help functions.
The level transmitter is approved for use in potentially explosive atmospheres when equipped
with the appropriate options.
1.3 Standards and approvals
DANGER!
In compliance with IECEx scheme rules, the IECEx version of the device described in these
Supplementary Instructions conforms to International Standards IEC 60079-0:2004, IEC 600791:2007-04, IEC 60079-11:2006, IEC 60079-26:2006, IEC 61241-0:2004, IEC 61241-1:2004 and
IEC 61241-11:2005. The Ex ia / Ex iaD and Ex d[ia] / Ex tD[iaD] versions are certified for use in
hazardous areas by KEMA Quality B.V. under IECEx KEM 06.0025X.
WARNING!
Carefully read the IECEx approval certificate. Obey the boundary conditions.
The certificate is given on the CD-ROM supplied with the device. You can also download the
certificate from our internet site.

GENERAL SAFETY INFORMATION 1
1.4 Equipment protection levels (EPL)
1.4.1 Ex ia / Ex iaD-approved devices
These devices are suitable for use in potentially explosive atmospheres of all flammable
substances in Gas Groups IIA, IIB and IIC. The Ex ia-approved device is certified for applications
for which an EPL of Ga, Ga/Gb or Gb is necessary. The Ex iaD-approved device is certified for
zone 20, zone 21/20 or zone 21 (combustible dust atmospheres).
DANGER!
The device must be fitted with the appropriate options.
1.4.2 Ex d[ia] / Ex tD[iaD]-approved devices
These devices are suitable for use in potentially explosive atmospheres of all flammable
substances in Gas Groups IIA, IIB and IIC. The Ex d[ia]-approved device is certified for
applications for which an EPL of Ga/Gb or Gb is necessary. The Ex tD[iaD]-approved device is
certified for applications in zone 21/20 or zone 21 (combustible dust atmospheres).
DANGER!
The device must be fitted with the appropriate options.
