(2)OPCN-1 master module (NP1L-JP1)
When a OPCN-1 master module is used, it is necessary to the stick-insulating sheet.
1) 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 nec-
essary to remove the insulating sheet for this work. For this operation, the operator must
remove static electricity accumulated on his body by means of a static elimination band or
the like before touching the station number-setting switch.
(3) FL-net ( OPCN-2 ) module (NP1L-FL1)
When the "FL-net ( OPCN-2 )" module is used, in order to control electromagnetic radiation noise emitted
from the communication cable, a ferrite core needs to be mounted at the base of the cable.
1) Mount the ferrite core at the base of the communication cable.
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.
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.
* Ferrite core mounting may be unnecessary if all of the communication cable is laid only inside the metal
enclosure, or even when it is laid outside the metal enclosure, if it is laid in EMI shielding tube or metal
tube so that no noise leaks out.
