Instruction on Voltage Input Mode Wiring
The total current value of the channels must be within the rated current (limit) for DC power
supply.
But if the total current value exceeds the rated current, reduce the number of channels to be
supplied at on time, and prepare the same DC power supply for each channel group.
In such a case, the polarity of power sources should be the same.
Mount ADV151, ADV161, AED5D, A1BD5D, AKB331 and AKB337 in the same cabinet.
When ADV151 or ADV161 is mounted in a cabinet different from that for AED5D or A1BD5D,
apply explosion-proof wiring defined in each country for AKB331 or AKB337.
