DEC Module 50/5
10.8.2 Low V5V operation
Alternatively, the DEC Module 50/5 can be operated with a supply voltage of
+5 VDC only. Thereby, the ex5 VDC power source must be connected
to pins [7] and [8] «+V
CC
» and, in addition, also to pin [11] «V
CC
Hall». This
wiring makes sure that the internally 5VDC supply voltage is fed
from external.
Warning
a
The supply voltage must be b4.75 VDC and +5.25 VDC. Voltages
above +5.5 VDC or swapping poles will destroy the unit.
