1. Important Safety Instruction
1.1. An Important Notice
1.1.1 For Parallel System installation, please refer to Parallel System
Installation Guide Part number 003-2302
1.1.2 Because of “small leakage currents” generated by the EMI filter of the
UPS, it is necessary to insure that the UPS is properly grounded before
connecting AC power to the input.
1.1.3 To ensure safety in all applications where a UPS is hard wired to the
Electrical Supply, ensure that the system is installed by a Qualified
Electrical Contractor.
1.1.4 The UPS has its own internal energy source (battery). When the UPS is
operating from battery power when no AC input is available, there will be
voltage at the output terminals.
1.1.5 Make sure that the AC Utility power source is correctly grounded.
1.1.6 Do not open the case, as there are no serviceable parts inside. Your
Warranty will be void.
1.1.7 Do not try to repair the unit yourself; contact your local supplier or
your warranty will be void.
1.1.8 Make sure that the rated input voltage of the UPS matches the
available AC mains voltage.
1.1.9 Use a certified input power cable with the correct plugs and sockets
for the appropriate voltage system.
1.1.10 To eliminate any overheating of the UPS, keep all ventilation openings
free from obstruction, and do not store anything on top of the UPS. Keep the
UPS 12 inches away from the wall.
1.1.11 Make sure the UPS is installed within the proper environment as
specified. (0-40℃ and 30-90% non-condensing humidity)
Form No. 003-2282 Rev G

1.1.12 Do not install the UPS in direct sunlight. Your warranty may be void
if the batteries fail.
1.1.13 Install the UPS indoors as it is not designed for installation outdoors.
1.1.14 Dusty, corrosive and salty environments can do damage to any UPS.
1.1.15 Install the UPS away from objects that give off excessive heat and
areas that are excessively wet.
1.1.16 If liquids are spilled onto the UPS, or foreign objects dropped into the
unit, the warranty will be null and void.
1.1.17 The battery will discharge naturally if the system is unused for any
length of time.
1.1.18 Recharge the batteries every 2-3 months if unused. If this is not done
the warranty will be null and void. When installed and being used, the
batteries will be automatically recharged and kept in top condition.
1.1.19 This UPS supports electronic equipment in offices,
telecommunications, process control, medical and security applications.
This UPS is NOT intended for use in the following application:
a. Medical equipment directly related to human life
b. Elevator, Metro (Subway) system or any other equipment related to
human safety.
c. Public system or critical computer systems.
1.1.20 Do not install the UPS in an environment with sparks, smoke or gas.
1.1.21 Make sure the UPS is completely turned off when moving the UPS
from one place to another. It might cause electrical shock if the output is not
turned off.
1.1.22 The UPS is equipped with a Maintenance Bypass Switch. Please
follow the procedures strictly to switch on/off the Maintenance Bypass
Switch.
Form No. 003-2282 Rev G

1.1.23 The UPS offers CVCF (Constant Voltage Constant Frequency) setting
function.
a. For correct setting and wiring, please contact your local agent.
b. Do not attempt to configure the UPS for CVCF by yourself;
otherwise your warranty will be void.
1.1.24 This UPS has been designed and constructed to protect your assets
from the wide range of power aberrations experienced on Utility power lines
today. It is your insurance for reliable, clean and stable voltage supply. It is
worth taking care to install the system correctly and to have it maintained
correctly by your local dealer.
1.1.25 SAVE THESE INSTRUCTIONS - This Manual Contains Important
Instructions that should be Followed during Installation and Maintenance of
the UPS and Batteries.
1.1.26 Intended for Installation in a Controlled Environment.
1.1.27 CAUTION – 6Kva - A load disconnect switch shall be provided by
others for the AC output circuit. To reduce the risk of fire, connect only to a
circuit provided with branch circuit over-current protection for 30 amperes
rating in accordance with the National Electric Code, ANSI/NFPA 70.
1.1.28 CAUTION – 8/10Kva - To reduce the risk of fire, connect only to a
circuit provided with branch circuit over-current protection for 40 amperes
rating in accordance with the National Electric Code, ANSI/NFPA 70.
1.1.29 Use No. 10 AWG, 60C copper wire and 22.1 lb-in Torque force when
connecting to terminal block.
1.2. Storage Instruction
For extended storage through moderate climate, the batteries should be
charged for 12 hours every 3 months by connecting the UPS input to an
appropriate power source and start the UPS according to the instructions in
this manual. Repeat this procedure every 2 months under high temperature
environment.

2. Product Introduction
2.1. General Characteristics
2.1.1 True online architecture continuously supplies in your critical device
with a stable, regulated, transient-free pure sine wave AC Power.
2.1.2 20KHz PWM sine-wave topology yields an excellent overall
performance. High crest factor capability of the inverter handles all highinrush current loads without a need to upgrade the power rating.
2.1.3 Multi-functional LCD/LED panel displays various conditions of the UPS.
The LED display shows the UPS working status, Utility Status and UPS
Abnormal status. The LCD display shows Input and Output Voltage,
Frequency, Load Status, Inner cabinet temperature, and Abnormal
conditions.
2.1.4 To protect the unit from overload, it automatically switches to bypass
mode in 160 seconds~ 40ms if loading is between 105%~ 150% of rating.
At 150% of rating, it switches to bypass mode immediately. The UPS will
automatically switch the load back to inverter mode once the overload
condition ceases.
2.1.5 If a short circuit is connected to the output the UPS will shut off the
output voltage instantly. The output voltage will remain off until the short
circuit is removed from the output.
2.1.6 Should the unit become overheated, the internal thermal Switch will
detect the heat and switch to bypass mode. When the unit is cooled it will
switch the load back to inverter automatically.
2.1.7 Fully digitalized control circuits built into the UPS enhance
functionality while providing a high-level of protection of the UPS.
Powerful Communication capability enhances its capability for remote
control and monitoring.
2.1.8 Maintenance-free sealed-type battery minimizes after-sales service.
2.1.9 Built in maintenance bypass switch provides an easy and safe
troubleshooting or maintenance function when the Utility is normal.

2.1.10 Providing four different working modes, such as Normal, ECO, CF50
and CF60, it may widely be used in a variety of applications.
2.1.11 DC-start function allows the UPS to be started during power outages.
2.1.12 Revolutionary battery management circuit analyzes battery
discharging status to adjust battery cut-off point and extend the life of
batteries.
2.1.13 Intelligent temperature-controlled fan extends the life of the fan and
reduces noise.
2.1.14 Built in diagnostics use fault codes, displayed on the LCD, to assist in
finding the cause of a problem with the unit.
2.1.15 In case the UPS is out of order, Fault status will be shown on the LCD
screen.
2.1.16 When the UPS is operated as a frequency converter under CF50 or
CF60 mode, the recommended load connected shall be 75% of rated
capacity if the input voltage is between 176~280Vac and 50% of the
rated capacity if the input voltage is 160~280Vac.

2.4. Communication Port Explanation
The Communication port on the UPS provides RS232 protocol to communicate
with UPS software for remote monitoring.
Available optional interfaces cards, which contains R2E (2nd RS232, SC-RS232),
RSE (RS485, SC-RS485), USE (USB, SC-USB), DCE (Dry Contact, SCContact/EPO), as well as SNMP card (SC-SNMP1), can be added according to
need. However, the R2E card, RSE card and USE card cannot be used
simultaneously.
The bundled software of the UPS is compatible with many operating systems such
as Windows 98, & 2000, ME, NT and XP. For other applications like Novell,
NetWare, Unix, Linux, please contact your local distributor.
When the optional interface cards are used together with the onboard RS232 port,
during communication the EPO signals (SC-Contact/EPO) will get the highest
priority in control command, then the SNMP/WEB card (SC-SNMP-1), then the
shutdown command at the DCE card, R2E, RSE and USE. Finally the onboard
RS232 port will get the lowest priority.
2.4.1 RS232
2.4.1.1.1. The RS232 interface settings
The RS232 interface shall be set as follows:
Baud Rate
