(6) Measures for the positioning modules
When one of the following modules is used, a ferrite core needs to be mounted at the base of all the cables
connected to the module as well as the power and FG cables leading to the power module mounted on the
baseboard on which the positioning module is also mounted.
NP1F-HC2/NP1F-HC8
NP1F-HP2/NP1F-MP2/NP1F-MA2
Wire to a power supply and grounding wire
Affix the insulating sheet supplied with the product on the station number-
setting switch.
Note:
For the purpose of explanation, a colored sheet is used in the photo
at left. The actual insulating sheet supplied with the product is
transparent.
Static discharge to the termi-
nal block does not occur.
Commendable ferrite core
: ZCAT 3035-1330 from TDK
Note:
If vibration or shock is applied to the product, a
strong force due to the weight of the ferrite core
may act on the cable to damage it. Be sure to af-
fix the cable to a firm object such as a duct so
that the cable does not swing under vibration.
2) Affix the static electricity-preventive insulating sheet on the station number-setting switch.
Take measures to prevent static discharge to the terminal block for the signal cable.
Affix the static electricity preventive insulating sheet to the station number-setting switch.
When a station number needs to be changed while the module is operating, it is once necessary to remove
the insulating sheet for this work. For this operation, the operator must remove static electricity accumu-
lated on his body by means of a static elimination band or the like before touching the station number-set-
ting switch.
