2 Introduction
The product described in this manual is a transformerless Uninterruptible Power System
(UPS). It is a true online, continuous duty, double conversion, static state, three-phase system,
providing conditioned and uninterruptible AC power to protect the customer’s load from all
nine power failures.
2.1 System description
The UPSs are used to protect sensitive IT equipment and prevent loss of valuable electronic
information, minimise equipment downtime, and minimise the adverse effect on production
equipment due to unexpected power problems.
The UPS system continually monitors incoming electrical power and removes the surges,
spikes, sags, and other irregularities that are inherent in commercial utility power. Working
with a building‘s electrical system, the UPS system supplies clean, consistent power that
sensitive electronic equipment requires for reliable operation. During brownouts, blackouts, and
other power interruptions, batteries provide emergency power to safeguard operation.
The UPS system is housed in single freestanding cabinets. The cabinets line up and match in
style and colour, and have safety shields behind the doors for hazardous voltage protection.
