Introduction
The information provided in this manual covers single phase 1000 –
3000 VA, uninterruptible power
systems, their basic functions, operating procedures, and emergency situations, also including
information on how to ship, store, handle and install the equipment. Only detailed requirements of
the UPS units are described herein, and installation must be carried out in accordance with this
manual. Electrical installations must also carefully follow local legislation and regulations. Only
qualified personnel should conduct these installations as failure to acknowledge electrical hazards
could prove to be fatal.

System description
Several different kinds of sensitive electrical equipment stay protected by a UPS (Uninterruptible
Power System) including computers, workstations, process control systems, telecommunications
systems, sales terminals, other critical instrumentation, etc. The purpose of the UPS is to protect
these systems from poor quality utility power, complete loss of power, or other associated problems.
Electrical interference abounds in many forms causing problems in AC power, from lightning,
power company accidents and radio transmissions to motors, air conditioners, and vending
machines, among others. So protection of sensitive electrical equipment is vital to protect against
power outages, low or high voltage, slow voltage fluctuations, frequency variations, differential and
common-mode noises, transients, etc.
In order to prevent power line problems reaching critical systems causing damage to software,
hardware and causing equipment to malfunction, the UPS helps by maintaining constant voltage,
isolating critical load output if needed, and cleaning the utility AC power.
2.1 General description
As a double conversion on-line UPS, it is able to supply uninterrupted, clean single-phase power to
your critical systems while keeping batteries charged continuously, regardless of whether utility
