Terminal Assignment For Sub-D Slot X1 - Stahl 9442/32-Serie Betriebsanleitung

Equipping and permissible mounting conditions
DANGER! Explosion hazard due to incorrect electrical project engineering!
Non-compliance results in fatal or severe injuries.
▶
Only plan and connect intrinsically safe connections for the CPU module.
• Adhere to maximum equipping and module assignment per socket:
- For a socket with three slots:
2 CPU modules and 1 power module (CPU redundancy) or
1 CPU module and 2 power modules (power redundancy)
- For a socket with four slots:
2 CPU modules and 2 power modules (system redundancy)
• Only mount one socket for each BusRail.
• Mount a maximum of 16 I/O modules for each BusRail. The maximum number of
I/O modules that can be installed is also dependent on the communication protocol and
functions being used in each case. For details on this, see the corresponding
IS1+ coupling descriptions.
• Adhere to the maximum system length (BusRail + BusRail extension) of 3 m.
• Secure all connection lines against tensile load and scuffing.
• Plan a distance of at least 50 mm for intrinsically safe and non-intrinsically safe electrical
circuits.
Project engineering specifications depending on the ambient temperature
Adjust mounting processes based on the maximum ambient temperature,
see the "Technical data" chapter.
Updating/replacing modules
Observe chapter 6.2.
