Self-regulating trace heating systems
intended for use in hazardous (potentially explosive) gas or combus-
tible dust atmospheres ("hazardous locations").
Operation is allowed with
one kind of heating cable in each heating circuit only
respect to the maximum heating circuit length
installed earth fault equipment protection and overcurrent protection
for each branch circuit
The approval and marking of the respective heating system, the tech-
nical data of the BARTEC Self-regulating trace heating cables and the
applicable documents must be observed.
For use with electrical systems, the relevant installation and operating
conditions (e.g. according to ATEX Directive 2014/34/EU,
EN 60079-0, EN 60079-14, EN 60079-17, EN 60079-30-2 and any
other relevant national standards) must be observed.

Specific Conditions of Use

For Specific Conditions of use see documents of components, the
system is built with, as it is:
General (IECEx DEK 20.0055X); (DEKRA20ATEX0093 X)
All power and data line cable entries to the trace heater boxes shall
be installed with Ex eb or Ex tb cable glands or blanking elements
providing a minimum ingress protection of IP66.
Supply cables and power cable entry glands shall be selected per
manufacturer's installation instructions for appropriate conductor size
and temperature range (see chapter "Checklist customized entry
port").
When used in TT and TN systems a residual current device according
to IEC/IEEE 60079 30-1, clause 4.4 point c) 1) shall be installed.
When used in IT systems an insulation monitoring device according to
IEC/IEEE 60079 30-1, clause 4.4 point c) 2) shall be used.
For the electrical data that are not marked, see Annex 1 to
NL/DEK/ExTR20.0058/00.
Coated aluminium Power boxes, type 27-54P2-****/**** and Cable
entries PS-120* type 27-59-G2-*
The enclosure must not be used in areas affected by charge-produc-
ing processes, mechanical friction and separation processes, electron
emission (e.g. in the vicinity of electrostatic coating equipment), and
pneumatically conveyed dust.
PBTW, Ex d Temperature Controller Type 27-54D*-****/****
The width of gap of the Ex d Temperature Switch is below the maxi-
mum values according to IEC 60079-1. Contact BARTEC for mainte-
nance or repair of Ex d Temperature Switch.
The capillary of the PBTW and PT100 wiring shall be part of a fixed
installation and shall be effectively clamped to prevent pulling or twist-
ing.
PBTW, PBTC, Temperature Controller Type 27-54**-****/****
Shall be applied for maintaining temperature only.

Design Guide for Hazardous / Industrial
Notice Technical data subject to change without notice.
No claims for damage arising from alternations, errors or misprints shall be allowed.
The capillary of the PBTW and PT100 wiring shall be part of a fixed
installation and shall be effectively clamped to prevent pulling or twist-
ing.
Heating system PLEXO TCS type 27-59P*-****/****
The classification of the temperature class of the PLEXO TCS Heating
System is done from the operator depending on the used heating ca-
ble. The ambient temperature range of PLEXO TCS Heating System
depends also of the used heating cable. This information is recorded
on the operator side in accordance with the specifications in the oper-
ating instructions / acceptance report. The documentation must be
kept secure.
Temperature Controller, ESTM type, 17-88C1-*22H/****
Cable glands shall be used that are certified for the applicable type of
protection and with suitable ratings. For EPL Db only cable glands
with integrated seal or gasket may be used.
In order to ensure safe operation of the Ex ib circuits, the ground or
earth connections of all electrical circuits connected to the Tempera-
ture Controller shall be installed using potential equalization between
the hazardous area and the non-hazardous area.
Shall be applied for maintenance temperature control only. The use of
optional Limiter ESTM-L, 17-88C1-*22H**** is not in the scope.
Self-Regulating Heating Cable Series PSB, type 07-5853-**** and
MSB, type 07-5854-****
Connections and terminations for installation with the Self-Regulating
Heating Cable Series PSB and MSB shall be certified according to the
requirements of the applicable standards for the types of protection for
potentially flammable gas or combustible dust atmosphere, or as the
requirements of IEC/IEEE 60079-30-1 as integral components. The
connections and terminations shall be suitable for the application and
correctly installed.

Foreseeable Misuse

The following activities are a misuse of the product and are not al-
lowed:
Use of the BARTEC Self-regulating trace heating cables for pur-
poses other than those described in the intended use
Installation, commissioning, operation, maintenance or disposal by
unauthorised or unqualified personnel
Work on live parts or circuits without switching off the BARTEC
Self-regulating trace heating cables or the system
Commissioning of damaged or faulty system components or incom-
plete installation.
Recommisioning after dismounting the heating grommet without re-
placing the heating grommet.
Unauthorized technical modification of the BARTEC Self-regulating
trace heating cables

Personal Qualification

For system planning, installation, commissioning, operation and mainte-
nance observe the requirements for personnel qualification according to
DIN/EN 60079-14, note appendix A.
