10.8.2 Low V5V operation
Alternatively, the DEC Module 24/2 can be operated with a supply voltage of
+5 VDC (±5 %). Thereby, the ex5 VDC power source must be con-
nected to pin [4] «+V
CC
» and, in addition, also to pin [6] «V
CC
Hall».
Warning
a
The supply voltage must be b4.5 VDC and +5.5 VDC. Voltages
above +6.0 VDC or swapping poles will destroy the unit.
