… 2 Use in potentially explosive atmospheres in accordance with
ATEX and IECEx
Installation instructions
ATEX / IECEx
The installation, commissioning, maintenance and repair of
devices in potentially explosive atmospheres must only be
carried out by appropriately trained personnel. Works may be
carried out only by persons, whose training has included
instructions on different types of protection and installation
techniques, concerned rules and regulations as well as general
principles of zoning. The person must possess the appropriate
competences for the type of work to be conducted.
When operating with combustible dusts, comply with
EN 60079-31.
The safety instructions for electrical apparatus in potentially
explosive areas must be in accordance with Directive
2014/34/EU (ATEX) and IEC 60079-14 (Installation of electrical
equipment in potentially explosive areas).
Comply with the applicable regulations for the protection of
employees to ensure safe operation.
Cable entries
Devices with type of protection ‘Ex d’ without supplied
cable glands
For devices with the ‘Ex d – flameproof (enclosure)’ type of
protection which are supplied without cable glands, observe the
instructions in Flameproof (enclosure) – Zone 1 on page 15.
For information on the cable gland used, refer to the relevant
data sheet and operating instructions.
Devices with type of protection ‘Ex d’ with cable glands
If devices in ‘Ex d – flameproof (enclosure)’ type of protection
with cable gland are ordered, an Ex d certified cable gland is
factory-installed.
Cable gland data
• Thread: 2 × M20 × 1.5 or 2 × ½ in NPT
• Temperature range: −50 to 85 °C (−58 to 185 °F)
• Cable outside diameter: 3.2 to 8.7 mm (0.13 to 0.34 in)
• Material: nickel-plated brass
The cable entry is only suitable for fixed installations and non-
reinforced cables with round and smooth plastic sleeves and
suitable outside diameter. The cables must be attached
appropriately in order to prevent them being pulled out or
twisted.
The operating instruction and approvals supplied with the cable
glands, as well as any applicable requirements in accordance
with EN 60079-14 must be taken into account accordingly.
Installation instructions for cable glands
The sealing rings of the cable glands harden at low
temperatures. Before installation, bring the sealing rings to a
temperature of at least 20 °C for 24 hours. Before inserting the
sealing rings and fixing them onto the cable gland, knead the
rings to ensure they are soft and flexible.
IP rating IP66 / 67 is only achieved by installing the black
neoprene sealing ring between the cable gland and the housing
and by observing the tightening torque of 3.6 Nm (Figure 2,
item 2).
Cables must be protected against extreme mechanical loads
(caused by tension, torsion, crushing, and so on). Even under
operating conditions, it must be ensured that the cable entry
remains hermetically sealed. The customer must provide a strain
relief device for the cable.
A40 mm
B12 mm
CØ8.5 / 12 mm
Figure 1: Stripping the connection cable
1.Check that cable used is suitable (i.e., check the mechanical
resilience, temperature range, creep resistance, resistance to
chemicals, outside diameter, and so on).
2.Strip the cable in accordance with Figure 1.
3.Check the outer sleeve for damage and soiling.
4.Insert the cable in the cable gland.
Figure 2: Tighten cable glands
5.Tighten the cable gland until the cable is firmly enclosed by
the sealing ring (Figure 2, item 1). Do not tighten more than
1.5--times of the specified torque on the housing (see
assembly instructions for cable gland)!

TTF300 FIELD-MOUNT TEMPERATURE TRANSMITTER | OI/TTF300-EN REV. G 11
Maintenance
Check the cable glands during each maintenance session. If the
cable is slack, retighten the cap(s) of the cable glands.
If it is not possible to retighten them, the cable gland will need
to be replaced.
M20 × 1.5 plastic cable gland for various types of protection
The optionally supplied M20 × 1.5 plastic cable gland has a
limited temperature range. The permissible ambient
temperature range of the cable gland is −20 to 80 °C
(−4 to 176 °F). When using the cable gland, make sure that the
ambient temperature is within this range.
The cable gland must be installed in the housing with a
tightening torque of 3.8 Nm. On the cable side, when installing
the connection of the cable gland and cable, check for integrity
to ensure that the required IP rating is met.
Electrical connections
Grounding
If, for functional reasons, the intrinsically safe circuit needs to be
grounded by means of a connection to the potential
equalization, it may only be grounded at one point.
Intrinsic safety installation check
If transmitters are operated in an intrinsically safe circuit, proof
that the interconnection is intrinsically safe must be provided in
accordance with IEC/EN 60079-14 as well as IEC/EN 60079-25.
The supply isolators / DCS inputs must feature intrinsically safe
input protection circuits in order to eliminate hazards (spark
formation).
In order to provide proof of intrinsic safety, the electrical limit
value must be used as the basis for the EC-type examination
certificates for the equipment (devices); this includes the
capacitance and inductance values of the cables.
Proof of intrinsic safety is said to have been provided if the
following conditions are fulfilled when a comparison is carried
out in relation to the limit values of the equipment:

Installation in a potentially explosive atmosphere
Transmitters can be installed in all kinds of industrial sectors.
Potentially explosive systems are divided into zones,
meaning that a wide range of different instruments are also
required. For this, pay attention to the country-specific
guidelines and certificates!
Note
Ex relevant specifications must be taken from the EC-type
examination certificates and other relevant certificates that
apply in each case.
With transmitters for PROFIBUS PA and FOUNDATION
Fieldbus H1 applications, FISCO interconnection methods can be
used.

The ‘flameproof enclosure’ type of protection is only achieved by
correctly installing a specially certified cable gland with the Ex d
type of protection with the corresponding marking.
The sensor instrumentation must be provided by the user in
accordance with the valid Ex-standards.
As far as the installation and mounting of components is
concerned (explosion-proof cable entries, connection parts),
only those components are approved which at the least
technically comply with the current version of the PTB 99 ATEX
1144 X type examination certificate and for which a separate
examination certificate exists. At the same time, it is imperative
that the operating conditions listed in the respective component
certificates are complied with.
The transmitter must be connected using suitable cable and
cable entries or pipeline systems that satisfy the requirements
of EN 60079-1 and for which a separate examination certificate
exists. If the transmitter is connected to pipeline systems, the
relevant sealing device must be affixed directly to the housing.
Cable entries (PG glands) and sealing plugs of simple design
must not be used.
Close unused cable entry in accordance with EN 60079.-1.
The connection lead must be routed securely and in such a way
as to ensure adequate protection against damage.
If the temperature on the entry parts is over 70° C, connection
leads with sufficient temperature resistance must be used.
The transmitter must be integrated into the local potential
equalization of the potentially explosive area.

The installation, commissioning, maintenance and repair of
devices in areas with explosion hazard must only be carried out
by appropriately trained personnel.
The operator must strictly observe the applicable national
regulations with regard to installation, function tests, repairs,
and maintenance of electrical devices. (e. g. NEC, CEC).
M20 × 1.5 plastic cable gland for various types of protection
The optionally supplied M20 × 1.5 plastic cable gland has a
limited temperature range. The permissible ambient
temperature range of the cable gland is −20 to 80 °C
(−4 to 176 °F). When using the cable gland, make sure that the
ambient temperature is within this range.
The cable gland must be installed in the housing with a
tightening torque of 3.8 Nm. On the cable side, when installing
the connection of the cable gland and cable, check for integrity
to ensure that the required IP rating is met.
