Introduction

The information provided in this manual covers Off-Line 500-850VA uninterruptible power system (UPS). This manual contains basic functions, operating procedures, and emergencies, also including information on how to ship, store, handle, and install the equipment. Only detailed requirements of the UPS units described herein. The installation must carry out according to this manual. The electrical installation must further comply with local legislation and regulations.

Installation

Rear panel view

*Figures only display available function; functions are not on unit if not marked.

Connection to Main and Load

• Follow all installation and safety instructions very carefully; failure to do so may cause hazardous situations to personnel and equipment.

• Ensure the main power voltage matches with UPS. (110V/220V)

• For electrical installation, closely observe the nominal current rating of the source.

• Check the equipment’s power requirement to prevent overloading situations.

• Do not connect devices that draw either massive power shortly or half-wave rectified current – such as hairdryer, vacuum cleaner, laser printer, and plotter.
  Note: Although you may use the UPS immediately, maximum back up time will not be available yet. It is recommended to charge the batteries for a minimum of 8 hours before use

• Connect AC input ground terminal to main supply ground

• Connect line in neutral supply conductors.

• Connect the loads to the output wire connector. (Wire Gauge 10-18 AWG)

• (Optional) To protect your telecom/internet system, use RJ45/RJ11 cable to install the input/output cable with matching in/out jack

Operation

Necessary information for the operation of the unit is covered in this chapter. Normally UPS runs automatically, but on a few occasions such as just after installation, all procedures are described herein.

General Description
As an Off-Line UPS, it provides reliable protection to your daily equipment while automatically charges the battery.

 Main power transfers to your equipment with surge protection
 During a power failure, the UPS immediately provides backup power from the battery.

Line-Mode/Battery-Mode
UPS will operate in Line-Mode that supports power and charge battery while connected to power. During a power failure, the UPS will switch to Battery- Mode, in which power is maintained from the battery. In case of failure time exceed Battery-Mode duration, UPS will shut down until voltage return to prevent battery discharge.

Diagnostic Test
While the advanced battery management system monitors the conditions of the batteries, it sends early warnings if a battery replacement is needed. Diagnostic tests can be performed from the control panel.

System Configuration
The UPS device and battery make up the system. Depending on site and load requirements, certain Vadditional options are available as tailored solutions. Please consider the following when planning your UPS system:

• The total demand for the protected system shall dictate the output power rating (VA). When measuring demand, please allow a margin for future expansion and calculation error.
• Battery-mode duration needs dictate the battery size. If the load is less than the UPS nominal power rating, then the actual backup time is longer.

“On/Off/Test/Silence” button

Turn on the UPS
Press the “ON” button until a single “beep” alarm disappeared or the LED display turns on.

Shut Down the UPS

• Press the “OFF” button for 3 seconds during Line/Battery-mode.
• (If applicable) To avoid electrical hazards, please turn off the internal/external input breaker. Then, turn off any external battery breaker and wait till all fans completely shut down.

Test
Press once to start self-test function during Line-Mode

Silence
Press once to enable/disable alarm buzzer during Battery-Mode
Note: Remote ON/OFF: You can connect external control, which will function the same as the
“On/off/Test/Silence” button.

Green mode

• The Green mode feature will enable UPS no-Load or light-load shutdown to maintain power consumption and battery life. During battery mode, the UPS will shut down approximately 4 min with no load/light load operating.
• Green mode can also be enabled or disabled via monitoring software.
• The UPS will indicate Green mode with follow up alarm after UPS start-up alarm.
• Green Mode enable: Triple Beep
• Green Mode disable: Double Beep
• Green Mode enable: When turning on UPS, please keep holding the “ON” button until a triple “beep” occurred.
• Green Mode Disable: Turn on UPS normally. Green mode disables in default.

UPS Configuration

UPS Manual test
Manual tests for UPS or battery can be conducted from the UPS configuration as well and are functional even when the UPS is not charging the battery.
Simple test: It’s recommended to conduct a simple simulation test when

1. The first use of UPS.
2. Adding new loads.

6 months’ regular check-up
Switch on the UPS and wait for the power indicator to light up, then unplug UPS to simulate the main power failure.
Manual Battery Test: Press the “test” button once. UPS will automatically conduct a self-test. Please note that the UPS will briefly switch to battery mode.

UPS Monitoring Connection

UPSMON Pro software (Or other power monitoring software) can further utilize the UPS with warning reminders, monitoring, control shut down, and setting adjustments. Using monitoring features requires connecting the UPS to a computer or the internet

Connect UPS to Computer with USB (Optional)/RS232 port.

• Locate the USB/RS232 port on UPS.
• Connect with factory-provided/approved communication cable.
• Ensure your computer can install and support power management software.
• Note: Either USB Port or RS232 port, only one port will function at a time.

UPS RS232 PORT

• The RS-232 interface uses a 9-pin female D-sub connector.
• The RS-232 port carries the data about utility, load, and UPS.
  Detail information about interface ports pins and their functions are available upon request. Please contact for technical assistance.

6. Maintenance

Please read the following instruction to ensure your safety and maintain a longer product lifetime.
This section contains detailed information about moving, maintaining, and placing the UPS. With a minimal amount of maintenance, you can expect the UPS to function smoothly.

Transportation
Please handle UPS with extreme caution since a high amount of energy is within the batteries. Keep the unit in position as marked on the packaging and never drop the unit.

Storage
Please read the following instructions if the UPS is not installed immediately:

• Store the equipment as is in its original packing and shipping carton.
• Do not store in temperatures outside the range of +15°C to +25°C.
• Protect the equipment from wet or damp areas and moist air.

5. Reconnect the battery and reinstall the cover.

APP-A. Troubleshooting

• Troubleshooting procedures give simple instructions in determining UPS malfunctions. Start the troubleshooting procedure if you witness any alarm indication.

Alarm

• The UPS has an audible alarm. When different situations occurred, UPS will alert users with display and buzzer.

Battery-mode (Slow alarm)
During battery mode, the alarm will beep every 2 seconds. The alarm will stop when UPS return to Line-mode.

Battery-Low (Rapid alarm)
During Battery-low (less than 30%), the UPS will beep every 0.5 seconds. The alarm will stop when UPS shutdown or returns to Line-mode.

Overload/Fault (Constant alarm)
When UPS operating with load exceeded its maximum capacity, UPS will emit a continuous alarm to warn an overload condition. UPS will automatically turn off to protect your essential load. Please consider remove or shutdown less- essential loads.
Also, when the unit encounters other problems (battery failure, charger failure), the unit emits the alarm. Please refer to the function description and troubleshooting chart to identify the precise cause.

Silencing Alarm
Here is the instruction to mute the active alarm or future alarm notification:
Note: During battery-mode, if the battery is low on power, the alarm will sound regardless of silent-mode enable/disable.
Silent alarm Enable/Disable: Press the “on” button during the Battery-Mode alarm.
If troubleshooting does not include or resolve your situation, feel free to contact for technical assistance.
