2.5 PowerWAVE 8000DPA ST (S2) Communications
2.5.1 Standalone cabinet communication
Figure 2.13 Standalone cabinet UPS module communications
Figure 2.13 illustrates the communication facilities within a standalone UPS cabinet. The diagram shows three fitted UPS
modules but of course this could be as many as 10 modules in the ST-200 model.
Module parallel control
Each UPS module contains a dedicated control system which responds to data generated by numerous control and
monitoring functions within the module itself together with data generated by the other UPS modules and transmitted
along the cabinet’s internal parallel bus. The inter-module signals carried along the internal parallel bus allows each
module to function as part of a parallel UPS system in terms of load sharing, synchronisation etc as previously described.
The internal parallel bus is implemented by a multi-way connector fitted to the backplane of the UPS module mounting
slots, so the module is automatically connected to the bus when it is inserted.
A module control panel, fitted to each UPS module, provides the means to monitor and control each module individually
and also transmit ‘system-wide’ command signals, such as load transfer requests, to all the modules in the system.
Customer interface facilities
As shown, the internal parallel bus is also connected to a communications interface board (CIB). This board provides a
summary data collection and processing point for the entire UPS system and offers a range of input/output
communications facilities that can be interfaced with an external remote alarm panel, BMS or IT management network.
The system control panel, shown connected to the customer interface board, is an optional control panel with a graphical
user interface that can be fitted to the UPS cabinet door. When used, the system control panel can monitor and control the
entire UPS system or each individual UPS module.
