2.6 Personal safety
2.7 Warnings and cautions
2.7.1 General
When it is required to open the instrument in an explosive hazardous environment.
Warning!
In hazardous areas it is compulsory to use personal protection and
safety gear. This can be:
• Safety helmet, fire-resistive overall, safety shoes, safety glasses,
working gloves, LEL-meter.
Pay attention to the kind of product in the tank. If there is any danger
for your health, wear a gas mask and take all necessary precautions.
Warning!
Take appropriate precautions when chemical or toxic product vapors
are present (compressed air, chemical protection suit, detection
equipment).
NOTE
The emitted microwave energy is far below the accepted limits for
exposure of the human body. The antenna generates a maximum
radiation of 0.1 mW/cm2.
Warning!
Make sure that all power to the device is switched off before you open
the covers of the device. Failure to do so may cause danger to
persons or damage the equipment. All covers of the device must be
closed before switching the power on again.
Warning!
Treat the flange surface of the cover and the housing with care.
Keep the flange surface free of dirt.
The O-ring must be present and undamaged.

2.10.1 EN302372-1 ANNEX B
The following installation requirements shall be fulfilled:
1 SmartRadar FlexLine instruments are required to be installed at a permanent
fixed position at a closed (not open) metallic tank or reinforced concrete tank, or
similar enclosure structure made of comparable attenuating material;
2 Flanges and attachments of the radar equipment shall provide the necessary
microwave sealing by design.
3 Sight glasses shall be coated with a microwave proof coating when necessary
(i.e. electrically conductive coating);
4 Manholes or connection flanges at the tank shall be closed to ensure a low-level
leakage of the signal into the air outside the tank.
5 Whenever possible, mounting of the radar equipment shall be on top of the tank
structure with the orientation of the antenna to pointing in a downward direction;
6 Installation and maintenance of the radar equipment shall be performed by
professionally trained individuals only.
NOTE
This device is certified to measure liquid levels in metal, concrete or
similar materials, enclosed tanks.
NOTE
The radiated output power of the device is far below the exposure
limits. Nevertheless, use the device in such a manner that the
potential for human contact during normal operation is minimal.
