GFK-2958E RSTi-EP User Manual 318
6.1.10 Arrangement of SIL Modules
An EP-19xx module can be positioned anywhere in the RSTi-EP station. All of the following output
modules up to the next EP-7641 module are safely disconnected (safety segment). Multiple EP-19xx
modules / safety segments can be set up in a single station.
Note: When using RSTi-EP EP-19xx modules, also refer to the Modules for Functional Safety Manual
(GFK-2956).
6.1.11 Preparation and the required tool
The DIN rail must already be installed. To mechanically install the RSTi-EP station, you will need a 3-
mm screwdriver.
• Lay out the modules in the intended sequence.
• Check whether the DIN rail feet can be moved on both end brackets. If necessary, loosen the
mounting screw until the DIN rail feet can be moved freely.
• If not done yet, fit an earth terminal to the DIN rail.
6.2 Assembling the RSTi-EP Station
Explosion risk - During assembly work, sparks can form and surfaces may
become excessively hot.
• Before assembly, make sure that there is not a potentially explosive
atmosphere.
• For applications in potentially explosive atmospheres, observe the
installation and construction requirements of EN 60079- 15 and/or
country-specific regulations.
Dangerous contact voltage:
• Carry out assembly and wiring work on the RSTi-EP station only when the
power supply is disconnected.
• Make sure that the place of installation (switch cabinet etc.) has been
disconnected from the power supply.
The product can be destroyed by electrostatic discharge.
The components in the RSTi-EP series can be destroyed by electrostatic
discharge.
• Ensure that personnel and work equipment are adequately grounded.
Note: For failure-free operation, the end brackets delivered with the network adapter have to be
installed to achieve a permanent set of the RSTi-EP station.
