1. Introduction
The information provided in this manual covers single phase 6000 – 10000 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.
2. 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 power fails or not.
In event that a power failure lasts longer than a UPS backup time, it will shut down avoiding
