Table 4.3: Power supply capacity DCNM‑APS / DCNM‑PS
Calculation examples
The following example gives you an indication of the maximum load to each DCNM‑APS or
DCN‑PS socket:
–
Socket 2: 50 m + DCNM‑MMD = 12.50 W
1
–
Socket 3: 10 m + DCNM‑MMD + 9x (2 m + DCNM‑MMD) = 4.50 + 12.50 + (9*1.19) +
(9*12.5) = 140.21 W
2
.
–
Socket 4: 10 m + DCNM‑MMD + 9x (2 m + DCNM‑MMD) = 4.50 + 12.50 + (9*1.19) +
(9*12.5) = 140.21 W
2
.
–
Socket 5: 10 m + DCNM‑MMD + 9x (2 m + DCNM‑MMD) = 4.50 + 12.50 + (9*1.19) +
(9*12.5) = 140.21 W

For socket 2, the cable power consumption of the cable does not need to be counted.
2
The shortest redundant cable does not need to be counted.
Redundant network
If a system network cable between the devices is accidentally disconnected or broken, signals
cannot be transmitted anymore. To prevent this from happening (and to ensure continuous
operation) a redundant system network cable (4) can be connected to a free high‑power
socket (3, 4, or 5).
