Wiring Fail-Safe Modules - Siemens SIMATIC ET 200S Installation And Operating Manual

Power Supply Requirements in Compliance with NAMUR Recommendations
Note
You must use only power packs or power supplies (230 VAC --> 24 VDC) with a power
failure ride-through of at least 20 ms to comply with NAMUR recommendation NE 21,
IEC 61131-2, and EN 298. The latest up-to-date information on power supply components
are available on the Internet at:

These requirements are also applicable for network devices and power supplies that are not
manufactured to ET 200S or S7-300/-400 configuration standards.

Wiring fail-safe modules

4.3
Same Wiring Procedure as for ET 200S
Fail-safe power modules, electronic modules, and terminal modules are part of the ET 200S
range of modules. They are wired using the same procedure as for all standard modules in
an ET 200S.
Refer to the
configuration of modules and the IM151.
Warning
When assigning signals of the F-DI module, remember that signals should only be routed
within a cable or a nonmetallic sheathed cable if:
•
•
Mounting Rails
Only 35 x 15 mm zinc-plated mounting rails in accordance with EN 50022 can be used for
installing ET 200S with fail-safe modules. Mounting rails with the following order numbers,
for example, comply with this requirement:
• 6ES5 710-8MA11
• 6ES5 710-8MA21
• 6ES5 710-8MA31
• 6ES5 710-8MA41
