1. Product description
The Ex-heating system HSB type 27-1780-**10/**** with the HSB
(type 07-5803-***A) self-limiting parallel heating tape or the Ex-
heating system MSB Typ 27-1980-1*10-****/**** with the MSB
(type 07-5804-2**X and type 07-5804-2**Y) self-limiting parallel
heating tape, assembled with a connection and remote end termination
system (installation kit 05-0091-0129** or kit 05-0091-0135**) in cold
connection technology, is set up as a stationary resistance heating
system for pipelines or containers in hazardous areas.
The Ex-heating system HSB type 27-1780-**10/**** is used in
Zone 1, 2, 21 or Zone 22 according to the certified explosion group II
and temperature classes T2, T3, T4. The Ex-heating system MSB type
27-1980-1*10-****/**** is used in Zone 1, 2, 21 or Zone 22 according
to the certified explosion group II and temperature classes T3 or T4.
After assembly the supply wires and the twisted protective braid of the
heating tape are always to be connected to terminals in an enclosure with
“increased safety“ protection class in conformance to the relevant
standards (EN 60079-0 and EN 60079-7).
Please read carefully as this operation manual will be
applicable for connection and termination with the cold
applied technology described for HSB and MSB heating
cables. Technical limits are to be found in the type
examination certificates.

3. Safety Instructions
The relevant installation and operating regulations must be
observed for electrical systems in hazardous areas (e. g. Directive
1999/92/EC, Directive 94/9/EC, IEC/EN 60079-14, IEC/EN 60079-17
and the DIN VDE 0100 series).
The requirements under EN 60519-1 and EN 60519- 2 must be adhered
to. Thermal Safety Class 0 under EN 60519-2 Section 13 is met by
the heating tapes design characteristics. The copper braid with a
resistance of < 18.2 W/km is suitable as a protective conductor.
The minimum requirements for circuits protection and control
requirements are defined in IEC/EN 60079-30-1 clause 4.3 and
4.4. The operator of an electrical system in a hazardous envi-
ronment has to keep the equipment in an orderly condition,
operate it correctly, monitor it and do the required maintenance
and repairs (IEC/EN 60079-14, IEC/EN 60079-17, IEC/EN 60079-19).
Read these instructions to avoid lethal injuries and damage
to property by use of the BARTEC self-limiting heating tapes
HSB type 07-5803-***A or BARTEC self-limiting heating
tapes MSB type 07-5804-2**X and 07-5804-2**Y in explosive
atmosphere.
4. Assembly of heating circuits
The assembly of all heat trace connections must be completed carefully
according to the manufacturer’s installation manual supplied with the
connection sets.
Connections and terminations for installation with this self-limiting
heating tapes shall be certified according to the requirements of the
applicable standards for their types of protection for potential explosive
gas and combustible dust atmospheres, as well as the requirements of
IEC/EN 60079-30-1 and IEC/EN 60079-31 (IEC/EN 61241-0) as integral
parts of this trace heating system.
For the connection of the BARTEC self-limiting heating tapes type MSB
and HSB to power certified glands, enclosures and terminals shall be
used that are suitable for the application and are correctly installed.
