1.1 Software history
"Firmware revision" agrees with NAMUR NE 53. It is a series of numbers used to record the
revision status of embedded software (firmware) in electronic equipment assemblies. It gives
data on the type of changes made and the effect that changes have on compatibility.
Data about software revisions is shown in menu C5.1.2 Identification. For more data, refer to
Function description on page 77. If it is not possible to refer to the device menu, record the serial
number of the device (given on the device nameplate) and speak to the supplier.

1.4 Radio approvals
1.4.1 European Union (EU)
This level transmitter is approved to be used outside metallic tanks.
LPR (Level Probing Radar) devices
Use approved personnel to install the device. If the device is operated in the open air (outdoors),
it agrees with the RED (Radio Equipment Directive) if you obey these instructions:
• The antenna must always point downwards. The boresight direction of the antenna must be
vertical. No other angles are permitted.
• Install the device more than 4 km / 2.485 mi away from radio astronomy sites.
• If the device is 4...40 km / 2.485...24.855 mi away from radio astronomy sites, do not install the
device more than 15 m / 49.21 ft above the ground.
INFORMATION!
LPR (Level Probing Radar)
LPR (Level Probing Radar)LPR (Level Probing Radar)
LPR (Level Probing Radar) devices measure level in the open air or in a closed space (a metallic
tank etc.). You can use LPR devices for TLPR applications. The LPR devices meet the
requirements of the RED (Radio Equipment Directive) for use in the member countries of the EU.

3.1 Pre-installation requirements
•Heat sources (sunlight, adjacent system components etc.) can increase the internal
temperature of the device and cause damage. Make sure that the internal temperature is not
more than the maximum limit. The maximum permitted ambient temperature is +80°C/
+176°F. The maximum permitted surface temperature is +80°C / +176°F.
•Do not subject the signal converter to heavy vibrations. The devices are tested for vibration
and agree with EN 60068-2-6. If there is vibration, we recommend that you use the electrical
cable clamp with a device hanger.
