Safety notes
5
– The screening should include a braided screen and should
not consist solely of foil screening, since the latter can be
easily damaged by cable tension and pressure.
– To ensure good immunity to interference at high frequencies
as well, the screening of the cable should be attached to the
screening rail at both ends of the cable.
Safety notes for installation and operation of the SPI 3
Please observe the following before connecting up the SPI 3 to avoid risk to personnel
and damage to equipment and to ensure that the SPI 3 functions correctly:
– The SPI 3 is designed as an interface between fieldbus devices with serial interfaces
and the PROFIBUS. Do not use the SPI 3 for any other purpose.
– The SPI 3 may only be installed or de-installed by qualified technical personnel with ap-
propriate electrotechnical qualifications. When connecting up the SPI 3, you must ob-
serve the guidelines in the VDE 0100 regulations for handling electrical equipment.
– Always mount the SPI 3 on a suitable top-hat rail.
– The cables used to connect up the SPI 3 should not apply any mechanical forces to the
device.
Danger!
Never open the case of the SPI 3 and do not make any modifications to the de-
vice.
Warning!
Small objects or liquids must not be allowed to enter the case of the SPI 3 (e.g.
through the ventilation slots) since this could damage the device.
Never cover up the ventilation slots in the case.
Large temperature differences between the storage location and installation site
can cause condensation to form within the case of the SPI 3, which can damage
the device. If large temperature differences are present, you should wait at least
3-4 hours after installing the SPI 3 and before switching on the power.
