2-3 Connecting I/O Power and I/O Cable
Use the following wire sizes to wire external I/O devices.
* Refer to the descriptions of individual DST1 models (Section 5) for the termi-
nal arrangement of the terminal block and wiring for external I/O.
Recommended Materials and Tools
Ferrules with Plastic Insulating Collars
Use the ferrules with insulating collars conforming to DIN 46228-4. Ferrules
with similar appearance but not conforming to the standard may not match the
terminal blocks of the DST1-series Safety I/O Terminals. (The wire dimen-
sions shown below are rough dimensions. Confirm before application.)
Note (1) If the terminal block is wired with ferrules, firmly insert them all the way in.
(2) When using 2-wire ferrules, the power lines must be of the same diame-
ter.
(3) When using 2-wire ferrules, the metal part of the ferrule must be inserted
straight into the terminal block.
