2-2-3 Adaptation of individual module
(1) T-link master/interface module (NP1L-TL1 / RT1)
When a T-link master module is used, it is necessary to mount the ferrite core at the base of the communi-
cation cable as well as affix insulating sheet. When the T-link interface module is used, it is necessary to
mount the ferrite core at the base of the communication cable.
1) Mount the ferrite core at the root of the communication cable.
2) 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. This is necessary only for the T-link master module (NP1L-TL1), and not necessary for the T-
link interface module (NP1L-RT1).
* 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.
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.
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 prod-
uct is transparent.
