invalidate the Ex approval of the SmartRadar.
NOTE
Only for use in ATEX and IEC Ex approved installations.
NOTE
Install the compound glands according to the instructions provided
by the manufacturer.
Warning!
If the SmartRadar is installed in a hazardous area:

Warning!
- Minimum incoming wire cross section should be at least 0.2mm2
and may consist of a single-, fine- or multi-wire. With the use of
wire with a cross section between t0.2mm2 and <0.5mm2, the
maximum current I [A] should be reduced to a maximum of I =
0.55A.
- With a minimum wire cross section of t0.5mm2 the maximum
current I should not be higher then 3A and may consist of a single-
, fine- or multi-wire.

4.11.1 Grounding
The SmartRadar housing must be properly grounded to the ground reference
(generally the tank), according to local regulations. This is a safety grounding
requirement.
4.11.2 Introduction
Location
The terminal compartment is located at the rear, inside of the device (refer to figure
4.7). If there is a SmartConn present, you use the terminals of the SmartConn (refer
to figure 4.6). These terminals are numbered identical to the terminal compartment in
the device.
Warning!
When measuring the ground resistance, use a suitable instrument
which is approved for use in hazardous areas.
Caution!
Safety depends on proper grounding. Check the resistance of the
ground connection directly after installation. The measured ground
resistance must be below the maximum prescribed by local and/or
national grounding requirements.
Caution!
The intrinsically safe options have been certified for use in hazardous
areas. Make sure that the certificate of approval is available on site
and act in accordance with the instructions as given in the certificate.
Caution!
Intrinsically safe wiring must be separated from all other wiring. The
cable lay-out must be in accordance with local and/or national
regulations.
NOTE
Connect the armouring of the cable externally in the cable gland at
both ends of the cable.
Installation FlexLine

Connections
The intrinsically safe cabling must enter at the gland (C) only. This entry is marked
"Ex-i". Refer to figure 4.6. "Ex-i entry with SmartConn". Blue marked cables are
recommended for the intrinsically safe options.
