1. Safety information
Safe operation of these products can only be guaranteed if they are properly installed,
commissioned, used and maintained by qualified personnel (see Section 1.13) in compliance with
the operating instructions. General installation and safety instructions for pipeline and plant
construction, as well as the proper use of tools and safety equipment must also be complied with.
WARNING: The maximum process fluid temperature must be suitable for use if the
unit is to be used in any potential explosive atmosphere. For the device maintenance
in a potentially explosive atmosphere, we recommend the usage of tools which do
not produce and / or propagate sparks.
1.1 Explosion proof warning
Please ensure the unit is being used and installed in conformity with local, regional, and national
explosion proof regulations.
- Refer to “8. Approvals”
-The "Local communication interface (LCI)" of the SP7-1* may only be used outside of the
explosion hazardous area with Um ≤ 30 Vdc.
-The positioner type SP7-1* may only be operated as a source of auxiliary energy with gases of
the group IIA and the temperature class T1 in outdoor applications or inside of buildings with
sufficient ventilation.
-The fed gas must be free of air and oxygen insofar as no explosive atmosphere can occur. The
exhaust gas must always let outwards.
-The equipment may only be used as a II 2 D type device in areas where the level of mechanical
hazard is ‘low’.
-Cable entries that meet the requirements of EN 61241-11 for Category II 2 D as well as the
ambient temperature range must be used.
-Prevent electrostatic charging due to propagating brush discharge when the equipment is used
for applications involving combustible dust.
1.2 Wiring
Every effort has been made during the design of the positioner to ensure the safety of the user,
but the following precautions must be followed:
i) Ensure correct installation. Safety may be compromised if the installation of the product is
not carried out as specified in this manual.
ii) Wiring should be carried out in accordance with IEC 60364 or equivalent.
iii) Fuses should not be installed in the protective earth conductor. The integrity of the installation
protective earth system must not be compromised by the disconnection or removal of other
equipment.
