Modulon DPH Series
The communication interfaces are hot swappable and located at two different places. One is on
the front of the UPS with front door open and the other is at the rear of the touch panel. Please see
Figure 4-1 .
NOTE:
The UPS has two different system cabinets, 20 ~ 80kVA and 20 ~ 120kVA. Their
communication interfaces’ locations are the same; thus, in this chapter, only the diagram of
20 ~ 120kVA UPS is taken as an example.
