WARNUNG Explosion Hazard
No connections are to be made to X5 unless the area is known to be
non-hazardous.
8.4.1 Signals
Each status of the 8 signals is displayed using a yellow LED (1...8).
There is a screw connection for each signal at the two terminal strips X2:
• terminals 1 to 8 for binary signals
• terminals 51 to 58 for reference points
The reference points of the signals are either at 1M potential or 1P
potential. The polarity is selected on the module using a solder link:
