1.1.2 Battery Announcements
It should use specified battery! Non-specified battery will damage UPS.
The required charging voltage of different brands and different types of battery are different. Before
using battery, ensure that the charging voltage of UPS is suitable for battery. If any doubt, please
consult manufacturer for support.
Battery operation must be performed in accordance with battery instructions, especially battery
wiring. Irregular operation will cause battery damage, even human injury.
It is prohibited to connect battery+ with battery-. The wiring for battery must be tightened. It is
prohibited to touch any two wiring terminals of battery or the bare terminals for wiring
simultaneously, or it may cause battery damage or human injury.
Prevent electrolyte leaking from battery, or the metal objects and circuit board will be corroded
by overflowing electrolyte, which will cause device damage and circuit board short circuit.
Battery should be placed far away from fire and all electrical equipments which easily cause
sparks to avoid human injury or unnecessary loss.
1.1.3 ESD Protection
To prevent human electrostatic damaging sensitive components on the circuit board, before touching
sensitive components, please wear a anti-static ring, and well connect the other end of the anti-static
ring to ground.

1.1.4 Grounding Requirements
High leakage risk! Before performing electrical connection, device must be grounded. The grounding
terminal must be connected to ground.
When installing device, it must be grounded first. When dismantling device, the grounding wire
must be dismantled at last.
Don't damage the grounding conductor.
Device should be connected to the protective earth permanently. Before attempting to operate
device, check the electrical connection to ensure that device has been grounded reliably.
1.1.5 Measurement When Power On
There has dangerous high voltage in the device. If touching device accidently, it may cause electric
shock. So, when performing measurement when power on, it must take protection measures(such as
wear insulated gloves, etc.)
The measuring device must meet following requirements:
The range and operation requirements of measuring device meets site requirements.
The connections for measuring device should be correct and standard to avoid arcing.
1.2 Operation Announcements
There exists high temperature and high voltage inside UPS. During installation, operation and
maintenance, please comply with the relevant safety regulations and operation procedures to avoid
human injury or device damage. The safety announcements mentioned in the user manual is only as a
supplement to the local safety regulations.

The operation and wiring for UPS should be performed by qualified person, which is to ensure that
the electrical connection meets the related standards.
The installer should be trained strictly, know all kinds of safety announcements and get right
operation methods before performing installation, operation or maintenance.
Don't mount and dismantle power wires before switching off power switch. Besides, ensure that
wires, wire labels are in accordance with the practical installation before performing wiring.
Touching high voltage or line directly or through damp objects will lead to lethal risk.
Only authorized professionals are allowed to open UPS! The input and output of UPS are
dangerous high voltage. Touching high voltage will lead to lethal risk.
Before maintenance, please disconnect AC power and battery to isolate power input and measure
the output terminal bars by a voltmeter to ensure that the input power is disconnected and in a
safe condition.
Even if all external power are disconnected, there still exists residual charge inside UPS, and the
output terminal bars may exist high voltage which may endanger human life. It is necessary to set
UPS aside for enough time (≥10 min) to release all charge before dismantling UPS.
As the battery doesn't isolate with AC input, there may exist dangerous voltage between battery
terminal and ground terminal. The battery pack should be insulated when installing or using it for
high voltage hazard concern.
Do not wear conductive objects, such as watches, bracelets and rings during operation.
The installer should have the operation qualification of high voltage and AC power. Maintenance
and repair for power system only can be done by qualified persons.

High leakage risk! Before performing electrical connection, device must be grounded. The
grounding terminal must be connected to ground.
Don't drill holes in the device! Inappropriate drilling will damage components inside device. Metal
debris generated by drilling entering device will lead to circuit board short circuit.
Any change of system configuration, structure or components will affect UPS performance. If the user
wants to make any change, please consult manufacturer in advance.
1.3 Operation Environment Requirements
Operation environment makes a certain difference in the life span and reliability of device. So, please
avoid using device in following environment:
The place where the operating temperature and relative humidity are beyond technical
specifications (Generally, the operating temperature is -5℃～50℃and the relative humidity is
0%-95%).
The place where it is exposed to direct sunshine or in rain.

2 Overview
This chapter mainly describes the model meaning, features, structure and working principle, etc.
2.1 Product Intro
The IST3-J series (1K-3K) UPS are with all high frequency, pure online, double-conversion,
intelligent features. They are the perfect power security for file server, enterprise server, center server,
mirco-computer, concentrator, telecom system, data center and others that require high quality power
protection. They are widely applied to the many key business areas, such as post, finance, network,
stock, railway, etc.
The AEC IST3-J series (1K-3K) UPS are with thesingle-phase AC input and single-phase AC output.
2.1.1 Model Meaning
□□□□
Output power
Figure2-1 Model meaning
The model meaning of AEC IST3-J series (1K-3K)UPS is as shown in Figure2-1. "□□□□"
means the output power. When "□□□□" is "1000", it means the output power is 1kVA. When
"□□□□" is "3000", it means the output power is 3kVA.
2.1.2 Features
Intelligent RS232 and USB communication
Through RS232 or USB standard port and UPS power management software, it can realize the three
remote function between the computer and UPS, monitor the running and electrical data of UPS on

the computer, perform ON/OFF operation remotely and support SNMP network adaptor (external,
connect with UPS through RS232 port), which makes UPS be a network new member.
High input power factor
Adopt the advanced active PFC technology, which eases load in the power grid. It is the new
generation green power.
High cost performance
Adopt many kinds of power conversations and high frequency PWM technologies, which is with
high efficiency, small volume, light weight, improves the running reliability and reduces cost.
Perfect protection
Equipped with the functions, such as output over-voltage protection, battery under-voltage protection,
input over-voltage protection, triple over-current protection, etc. and solve the problems of the high
frequency UPS, such as poor adaptability in the power grid and weak anti-impact ability.
Low mains input voltage
Adopt the independent rapid detection technology. When the mains input voltage is 120V, which is
the lower limit, the battery still doesn't discharge. Therefore, in the mains mode, all output power gets
from the power grid, which is to ensure the battery is still in the 100% energy storage status, reduce
the battery discharge times and prolong the working life.
