General Requirements
1.1
Safety Instructions
•
The REX 3900 gauge must be installed by suitably trained personnel according to the accompanied instructions and in accordance
with the applicable code of practice.
•
An “X” suffix on the approval number (e.g. Baseefa
03ATEX0071X) indicates that special conditions for safe use
apply.
•
Make sure that the connected power supply is in accordance with
the marking on the REX 3900 gauge.
•
Select external fuse rating with respect to area temperature classification (T1-T6) and maximum expected ambient temperature to
prevent overheating of the W11 wiring (0.5 mm2), see Figure 3-1.
Example: maximum allowed (fault) current in a T4 installation with
70°C ambient is 7.5 A according to the lead seal compartment certificate PTB 97 ATEX 1047 U.

Chapter 2 Explosion Protection Techniques
Explosion Protection Techniques
TankRadar REX equipment is often used in areas where flammable
materials are handled and where an explosive gas atmosphere may be
present, so called hazardous areas. To protect the environment and the
personnel, precautions must be taken to ensure that this atmosphere
cannot be ignited. Consequently, equipment within hazardous areas
must be explosion protected.
A number of different explosion protection techniques have been
developed over the years. Intrinsic Safety, Flameproof/Explosionproof
enclosures and Increased Safety are different techniques.
The basic principles of explosion protection are:
2.1
•
Flammable materials are grouped according to the energy needed
to ignite them.
•
Equipment located in hazardous areas are classified according to
the maximum surface temperature that it can produce and this
must be safe with the flammable gases that may be present.
•
Hazardous areas are classified according to the probability that an
explosive atmosphere is present, and this dictates whether or not
a particular explosion protection technique may be used.
Intrinsic Safety
Intrinsic safety, IS, is based on the principle of restricting electrical
energy available in hazardous-area circuits such that any sparks or hot
surfaces, that may occur as a result of electrical faults in components,
are unable to cause ignition. Intrinsic safety is the only technique
accepted for Zone 0 hazardous areas. For example, temperature
measurement with the DAU is intrinsically safe.
Note!
Special care and skills is necessary for troubleshooting in Intrinsically
Safe circuits.
Instruments for troubleshooting in Intrinsically Safe circuits must be
approved for the intended use.

Chapter 2 Explosion Protection Techniques
2.2
308016EN, Edition 5
April 2013
Flameproof/Explosion Proof
Flameproof/Explosion proof enclosures can be used when an explosion
is allowed inside the enclosure as long as it does not spread to the
outside. The enclosure must be strong enough to withstand the pressure
and must have narrow gaps to allow the pressure to escape without
igniting the atmosphere outside the equipment.
Note!
2.3
The flameproof/explosionproof enclosure must not be opened while the
unit is powered or when an explosive gas atmosphere is present.
Damaged enclosures must be taken out of service.
All cover fastening screws must be present and firmly tightened.
Increased Safety
This type of protection is intended for products in which arcs and sparks
do not occur in normal service nor under fault conditions, and in which
excessive surface temperatures are prevented. Increased Safety is
achieved by enhancing insulation values and creepage and clearance
distances above those required for normal service, thus providing a
safety factor against accidental breakdown. Electrical connections are
carried out in such a way that self-loosening is not possible.

Safe Connection of TankRadar REX
3.1
Cabling
The permanently attached cables are to be suitably terminated and
protected against impact. On the REX gauge this must be applied for
cable outputs W11 and W12.

Note!
Integrated Junction Box, JBi
The cover of the Integrated Junction Box may not be opened while
energized.
The intrinsically safe wiring to the internal TIC/TMC Board at output W12,
must be adequately segregated from the nonintrinsically safe wiring to
output W11.
3.3
Customer Supplied Junction Box
Customer supplied junction box, used for connection of output W11 to
customers field cabling, must be certified for use in hazardous area.
Leads from Radar Tank Gauge to junction box must be protected
according to national code of practice.
The intrinsically safe wiring to the internal TIC/TMC Board at output W12,
must be adequately segregated from the nonintrinsically safe wiring to
output W11.

Grounding
TH3900_GroundLug.eps
The housing must be grounded according to national code of practice.
Normally this means that the grounding lug on the flameproof enclosure
is connected to a potential equalizing network, normally the tank shell.
Figure 3-2. Grounding lug.
If the enclosure is connected to a tank structure without a potential
equalizing network, the protective ground with the power supply must not
be connected.

Chapter 4 Installation of Rosemount TankRadar
Installation of Rosemount TankRadar REX
According to Underwriters Laboratory (UL)
The enclosed "SYSTEM CONTROL DRAWING FOR HAZARDOUS
LOCATION INSTALLATION" drawing number 9150072-966, shows
specific requirements which have to be fulfilled to secure a safe
installation and use of Rosemount TankRadar REX in hazardous area.
The approval plate on explosion proof enclosure indicates installed
options.
Omission may jeopardize safety, and Rosemount Tank Radar AB will not
take any responsibility if requirements in the drawing are not fulfilled.

Note 1. Make sure a continous electric path exists from the cable shield to Radar Unit chassis. Shorter
cables may be specified for performance reasons. See installaton manual.
Note 2. W12 is optional and may contain up to 15 wires connected to six separate intrinsically safe circuits.
Separation between different IS circuits must be maintained in junction boxes.
Note 3. The WBS 500 from Oy Labkotec AB is an acceptable alternative.
Note 4. The intrinsically safe wiring must be in accordance with the National Electrical Code ANSI/NFPA 70, NEC
Article 504 and ANSI/ISA RP12.6. In Canada, the installation must be in acordance with the Canadian Electrical
Code, CEC Part 1.
Note 5. The ground of the radar unit must be connected to earth ground of the AC feeder supply circuit. The
resistance between the ground lug and the earth ground must be less than 1 ohm.
Note 6. The radar unit must not be powered by or connected to equipment that uses or generates more than
250V RMS with respect to earth ground.
Note 7.The outputs at W12 are intrinsically safe "ia" for use in Class I, Zone 1, Group IIB; Class I, Division 1,
Groups C and D Hazardous Locations.
Note 8. Intrinsically safe apparatus must be simple apparatus or be third party approved such that:
Voc <= Vmax, Isc <= Imax, Ca >= Ci + Ccable and La >= Li + Lcable.
Note 9. For Ccable and Lcable, if the capacitance per foot or the inductance per foot is not known, then the following
values shall be used: Ccable = 60pF / foot and Lcable = 0.2uH / foot.
Wiring must be protected by
explosionproof (flexible) conduit.
