Safety Instructions
2.1
Intended Use
The junction box with electronic thermostat module PBTC is intended for use as a temperature controller in electrical trace heating
systems.
The junction box with electronic thermostat module may only be installed in trace heating systems that have been designed by trained
and qualified personnel with specific expertise and experience in explosion protection and trace heating systems.
It can be operated only with
Resistance Temperature Device Pt100
Appropriately designed over-current protection device
The self-limiting BARTEC heating cables type PSB, MSB, HSB+ or HTSB
End cap mounted on the heating pipe end
Completely filled out acceptance test report
The junction box with electronic thermostat module may only be operated with one heating cable; the maximum permissible heating
cable length must be observed.
The approval and marking of the respective heating system, the data sheet of the heating cable type and the design guide 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. Information on
the type plate, the EU type examination certificate must be observed. Technical data on the thermostat module and in the operating
instructions must be observed.
