2: General Description
• A range of UPS output voltages (200/208/220/230/240V) can be selected to suit the local supply or specific load
voltage requirements.
• An overload detection system automatically switches the UPS output from its inverter to an internal bypass in the
event of an overload that exceeds the rated inverter capacity; and automatically switches back to the inverter mode
once the overload condition clears.
• An output short-circuit detection circuit turns off the UPS and disconnects its output supply until the cause of the
short circuit is manually remedied.
2.2
PowerWave 1000 Model range
The PowerWave 1000 UPS range compromises 4.5 kVA, 6 kVA, 8kVA and 10 kVA models, each of which comprises two
matching enclosures. The main UPS enclosure contains the major UPS power components, including a rectifier, battery
charger, inverter and static switch; and the second enclosure contains the UPS battery pack.
The enclosures can be configured as a floor-standing tower unit, or installed in a standard 19" rack. An accessory pack
containing all the parts necessary to prepare the enclosures for either type of installation is supplied with the UPS.
When installed as a tower system, the UPS and battery enclosures are mechanically attached together to form a single
unit. For 19" rack mounting it is usual to fit the UPS system near the bottom of a rack with the UPS enclosure mounted
immediately above the battery enclosure – see chapter 3 (Installation) for mechanical configuration details.
Optional equipment, designed to enhance the overall UPS installation, include a matching extended battery enclosure, an
external (maintenance) bypass enclosure and an isolation transformer.
The PowerWave 1000 UPS module can be operated as a stand-alone UPS, or up to four modules can be connected in
parallel and configured to operate as a multi-module UPS system. A multi-module configuration is generally chosen either
to increase a system’s total output power capacity or to increase the system’s overall reliability by providing module
redundancy.
In this manual the terms ‘multi-module system’ and ‘parallel system’ are synonymous.

Functional description of operation
This section describes:
• The internal operation of an individual UPS module (see paragraph 2.3.1).
• The UPS operational modes (see paragraph 2.3.2).
• Multi-module system operation and paralleling considerations (see paragraph 2.3.3).

Key Point:
All the UPS modules connected to a parallel system must be of the same model type and power
rating.
