Wiring the FM 350-1
3.2 Wiring front connectors
FM 350-1 Counter module
32 Manual, 05/2011, A5E03648639-01
Terminal 2 (1M) of the front connector must have a low-resistance connection to the ground
of the CPU. If you supply the encoder with an external voltage, you must also connect the
ground of this external voltage with the CPU ground.

Figure 3-3 Details Regarding the Connection of an Incremental 24V Encoder
● Use flexible cables with cross-sections of 0.25 to 1.5 mm

.
Note
If the encoders are supplied via the module, the cable cross-section must be large
enough to carry the required voltage to the encoder despite voltage drops over the cable.
This applies especially in the case of incremental 5 V encoders.
● You do not need wire end ferrules. If you use wire end ferrules then use only those
without insulation collar in accordance with DIN 46228 Form A, short version!
