Description
2.1 Reliability and Quality Standards
Congratulations on your purchase of the PowerWAVE 9000 DPA UPS.
By using a unique modular construction and incorporating the latest technological developments in power
engineering, the PowerWAVE 9000 DPA represents a completely new generation of transformer-less 3
phase UPS-System. High reliability, upgrade ability, low operating cost and excellent electrical performance
are just some of the highlights of this innovative UPS solution.

given in Chapter 8 of this manual.
2.2 PowerWAVE 9000 DPA System
PowerWAVE 9000 DPA is a truly modular system based on a range of 10kVA to 45kVA UPS power modules
that can be connected in parallel to form a redundant-module system. The UPS modules are housed in free-
standing cabinets which are purpose designed to contain up to one, three or five modules. Two cabinet
ranges are available as standard – the ‘MD’ cabinet range is designed for use with 10kVA-25kVA modules
(see Figure 2.2) , whereas ‘MX’ cabinets are used with modules from 30kVA to 45kVA (see Figure 2.3) .
Cabinets designed for three (or fewer) modules also contain the UPS batteries; however an additional,
external battery cabinet can be used to extended the battery autonomy time if required. An external battery
cabinet is always required for cabinets designed for 5 UPS modules. A range of battery cabinets of matching
style and colour is available to sit alongside the UPS cabinets to provide a matching suite.
2.3 System Configuration
The PowerWAVE 9000 DPA system configurations are described below.
2.3.1 Single/Parallel module configurations
Within the UPS cabinet, the power modules can be configured in one of two ways:
Single-module system
As its name suggests, a ‘single-module’ system comprises a cabinet fitted with just one UPS module, even if
the cabinet is designed to house several modules – for example a TRIPLE DPA-75 or -150, UPGRADE DPA-
125 or -250 fitted with a single module is still considered as a ‘single’ module system.
Parallel-module system
A ‘parallel-module’ system employs several modules (of the same rating) operating in parallel within the
same cabinet (e.g. TRIPLE DPA-75) using the DPA technology
(see paragraph 2.4.4) .
Key Point: All the modules fitted within a cabinet must be of the same rating – i.e. it is not possible
to mix 10kVA and 20kVA modules in the same parallel system.
