RSTi IO Station spacing

Figure 8
All the dimensions mentioned are in 'mm'.
RSTi Network adapter and IO modules should be mounted horizontally with minimum
clearance as shown above to meet product performance and reliability specifications by
providing adequate airflow around the modules. Other mounting orientations may affect
system performance, reliability and agency approvals, and are therefore not recommended.

Connecting Cables

Connecting Unshielded Cables
Unshielded cables for I/O devices and supply voltages are connected using the spring clamp
terminals. Signals up to 250VAC/DC and 5A with a conductor cross-section of AWG 14 – 24
can be connected.
For terminal assignments, please consult the appropriate module data sheet.
Follow these steps when wiring:
1.
2.
3.
Installation
Strip 8mm (0.3in.) off the cable. Module wiring is normally done without ferrules.
However, it is possible to use ferrules. If using ferrules, make sure they are properly
crimped.
Push a screwdriver into the slot for the appropriate connection (#1 above) so that
you can plug the wire into the spring opening.
Insert the wire (#2 above). Pull the screwdriver out of the opening. The wire is
clamped.
