Installing the FM 351 Positioning Function Module

No special protective measures (ESD guidelines) are required for the installa-
tion of the FM 351 Positioning Function Module.
Warning
!
Only mount the FM 351 Positioning Function Module when the CPU is in
the STOP operating state.
If you disregard this stipulation, damage may be caused to the connected
peripheral equipment.
You will need a 4.5 mm (0.25 in) screwdriver to install the FM 351 Position-
ing Function Module.
The following list describes how you mount the FM 351 Positioning Function
Module onto the rail. Further information about the installation of modules
can be found in the manual S7-300 Programmable Controller, Hardware and
Installation.
1. An expansion bus is included with the FM 351 Positioning Function Mod-
ule. Plug this onto the module bus plug to the left of the FM 351 Position-
ing Function Module. (The bus plug is located on the back panel, and you
must loosen the module again if necessary).
2. If further modules are to be mounted to the right, then first plug the ex-
pansion bus of the next module to the right-hand bus plug on the FM 351
Positioning Function Module.
If the FM 351 Positioning Function Module is the last module in the row,
do not plug in any expansion bus.
3. Screw the FM 351 Positioning Function Module firmly (tightening torque
approx. 80 ... 110 Ncm).
4. After installation you can allocate a module location number to the
FM 351 Positioning Function Module. For this, there are module location
labels which are included with the CPU.
The scheme to be adopted for numbering and how you fit the module
location labels can be found in the manual S7-300 Programmable Con-
troller, Hardware and Installation.
5. Mount the shield support element.
