Depending on local regulations this device can be cabled by using compound
glands, direct entry or conduits.
Warning!
Only use Ex-d certified materials of an appropriate IP value.
Warning!
Improper installation of cable glands, conduits or stopping plugs will
invalidate the Ex approval of the SmartRadar.
NOTE
Only for use in ATEX and IEC Ex approved installations.
4.10.1 Compound glands
Explosion proof (Ex-d) compound glands with an appropriate IP value must be used.
NOTE
Install the compound glands according to the instructions provided
by the manufacturer.
4.10.2 Conduits
Explosion proof (Ex-d) conduits with an appropriate IP value must be used. Refer to
the type plate on the device.
Warning!
If the SmartRadar is installed in a hazardous area:

4.11 Electrical connection
Warning!
Cables must always comply with the defined cable specifications.
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.
NOTE
The field cabling entering the SmartConn box must be as short as
possible.
NOTE
Depending on the ambient temperature classification the cables
must be suitable for Ta > 70 °C.
23
FlexLine
4.11.1
Installation
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.
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.
4.11.2
Introduction
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.
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.
24
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.
Fig. 4.6 Ex-i entry with SmartConn
A Blue terminals, for intrinsically safe connections.
B Grey terminals, for non-intrinsically safe connections.
C Glands for intrinsically safe cabling only.
NOTE
The SmartConn box is also available with 6 cable entries.
Terminals
The terminal compartment is divided into two zones:
25
FlexLine
Installation
Fig. 4.7 Terminal layout without SmartConn
• Blue terminals (A), for intrinsically safe connections, such as HART, VITO and
SmartView.
• Grey terminals (B), for non-intrinsically safe connections.
The indices of the terminals are variable. For each option there are indices on the
terminal row. They are specified in a label attached in front of the terminal row, as is
schematically indicated in figure 4.8.
The terminals for the power supply are standard.
Some terminal contacts can be double labelled. In this case the white text on black
label is the first option for connection. The black text on white label is the second
option for connection.

4.11.3
Installation
Non-intrinsically safe connections
The non-intrinsically safe connections are connected to the grey wiring terminal.
If local and or national regulations allow, the power supply, Enraf fieldbus and
hardware relay outputs can be combined in one, unshielded, cable.
A separate cable can also be used for each.
Power supply
Connect the power supply to either:
- DC: 24 - 65 Volt
- AC: 65 - 240 Volt
NOTE
The DC polarity is not critical.
NOTE
Install an explosion proof mains switch in the mains cable to the
SmartRadar.

4.12 Finishing installation with SmartConn
Warning!
Check if the separation between intrinsic and non intrinsic cabling is
sufficient and complies with any local and/or national regulations.
1. Replace the cover on the SmartConn.
2. Tighten the 4 bolts of the cover. Use an Allen key (4 mm).
3. The installation is now completed.

4.13 Finishing installation without SmartConn
Warning!
Tighten all bolts with a torque of 30 Nm (711 ft·lbf) to prevent danger of
explosion!
Caution!
Always clean the flange of the housing and the cover, before you
close the cover.
4.13.1 Close the cover of the device
Warning!
Make sure the flange of the housing is clean and the O-ring is not
damaged before closing the cover.
1. Close the cover. Make sure that the cover does not squeeze any cables inside the
housing.
2. Tighten the 16 bolts of the cover. Tighten the bolts crosswise. Use an Allen key
(8mm).
4.13.2 Replace the top cover
1. Open the display cover.
2. Place the 2 hooks at the rear of the top cover behind the axis of the cover.
3. Push down the top cover carefully.
4. The installation is now completed.
