5.5 Installing the Terminating Module and the Slot Cover
Properties
• The distributed I/O device ET 200iSP is terminated with the terminating module at the right
end of the ET 200iSP. If you have not plugged a terminating module, then the ET 200iSP is not
ready for operating (EMC is not guaranteed), the ET 200iSP starts up but pulling an electronic
module leads to a station failure.
• Pulling an electronic module leads to a station failure of the ET 200iSP.
• To mechanically secure the ET 200iSP, you must screw the terminating module tightly onto
the mounting rail.
• If your ET 200iSP conguration leaves you with a gap in the last slot, you must install the
reserve module or the slot cover in this slot:
– Install a slot cover if the ET 200iSP will not be expanded in the future. The slot cover is
integrated in the terminating module.
Replacing the slot cover with an electronic module during operation will cause a station
failure of the ET 200iSP.
– Install a reserve module if you want to use the free slot for a future expansion (by means
of an electronic module).
• The terminating module accompanies the terminal module TM-IM/EM and TM-IM/IM.
Requirements
The last terminal module of the ET 200iSP is mounted.
