have dangerous voltage even if the main power is disconnected.
6. Please remove the cable between the battery & UPS before repairing. It’s necessary to wait
for another 5 minutes for discharging, because of the dangerous voltages.
7. The wires should be fastened to the terminals. It is prohibited to short the anode and cathode
of battery. It’s prohibited to touch any two of wire connectors or bare end of connecting wires.
Otherwise, it may lead to damage of battery or personal injury.
8. Please keep the battery away from the fire and all the equipment that may cause spark to
prevent the danger and damage.
9. Please do not open or shatter the battery, the overflow electrolyte is with causticity that may
be harmful to life.
10. Please contact the professional personnel of the local dealer or the special maintenance
station for any trouble-shooting. Random disposal of the trouble is not allowed.
11. This is an A-grade product with electromagnetic compatibility.
12. This equipment must be installed and serviced by qualified personnel.
13. Before you replace the battery of different brand and different type, make sure the charging
voltage is matching with UPS charging voltage due to the different required charging voltage
of different battery, If any doubt, please consult with the manufacturer. Any changes of the
system configuration, structure and composition will influence the performance of UPS,
please consult with the manufacturer in prior before doing any changes.

1.Overview
1.1 Profile
Rack mount (1-3kVA) series UPS are total high frequency, pure online and
intellectualized UPS. They are also ideal power guarantee for file server,
enterprise server, central server, microcomputer, concentrator,
telecommunication system, data center, medical facilities and those who
requiring high quality power protection. They can be widely used in many key
business areas such as post & telecom, finance, network, securities and
railway, etc.
Rack mount (1-3kVA) series UPS are single-phase alternating current input
and output. Each series has two products including standard type and long
backup model.

1.3 Primary Functions and Characteristics
1．Intelligent RS232 communication function: With RS232 standard data
interface and UPS power management software, realize three
remote-control functions between computer and UPS, computer
supervises UPS operation and electric parameters, and realize
long-distance power on/off function, as well as supporting SNMP
network adaptor (outlaid, connecting UPS through RS232 interface),
which enables UPS to directly become the new member of network.
2．High input power factor: Adopt advanced active PFC technique, which
alleviates load on electric network and represents green power supply of
new generation.
3．High performance-price ratio: Adopts multiple power transfer and high
frequency PWM technique, high efficiency, small size and light weight as
well as improving operational reliability and reducing manufacturing cost,
which lowers the cost of the system design for customers.
4．Perfect protection function: Possess such functions as output
low-voltage protection, battery low-voltage protection, input low-voltage
protection and triple overflowing protection, etc and overcome previous
defects such as high frequency UPS' poor adaptability and weak
resistance to shock for electric network.
5．Low commercial power input voltage: Adopt independent quick detection
technique, even at the lower limit 120V of commercial power, the battery
remains off discharge, thus all energy output are taken from electric
network, ensuring the battery in the state with 100% energy storage,
while at the same time decreasing the battery discharge times and
prolonging its life.
1.4 Precautions
Abide by the following general safety precaution during operation or
maintenance.
1．Please don't remove the cover. This system can only be maintained or
repaired by professional maintenance personnel.

2．Protective ground terminals should be connected to earth end for sure.
3．High leakage danger! Connect to the ground before connecting UPS.
4．Install this UPS indoors with both temperature and humidity under
control and without dust.
5．The electric power of this UPS has multiple sources. Before maintaining,
cut the alternating current, exterior battery or interior battery's air switch
to isolate the input energy.
6．Even if the AC power supply has been cut off, the danger from battery's
high voltage inside the UPS still exists.
7．If battery circuit has not been isolated from AC input, dangerous voltage
may possibly exists between battery terminal and ground terminal.
8．High voltage endangering personal safety exists in the storage battery
of this UPS. Please pay attention to insulation during installation and
use.
9．Improper handling of acidic battery leads to leakage risk of chemistry
dangerous substance and corrosive liquid.
10．Dripping condensation should be happen if machine was operated under
low-temperature environment. So please install and use machine when
machine was full-dry, or there will has dangerous of electric shock.
Warning: Input and output voltage of this equipment is dangerous high voltage,
which can endanger personal life or safety. Please read carefully this Manual
during installation, operation and before use. Pay attention to various caution
nameplates and caution statements. Professional maintenance personnel
without proper authorization are not allowed to remove off the case cover of
this equipment.
