Communication Port

The communication port on the UPS provides for RS-232 communication with the UPS software to remotely monitor the power and UPS status.

You may use optional interfaces cards for R2E (second RS-232), RSE (RS-

485), USE (USB), DCE (Dry Contact), and SNMP. However, the R2E card, RSE card and USE card must not be used simultaneously.

The software bundled with the UPS is compatible with many operating systems such as Windows 98, 2000, ME, NT and XP. For other applications such as Novell NetWare, Unix, or Linux please contact your local distributor for a proper solution.

When the optional interface cards are used together with the onboard RS-232 port the EPO signals will get highest priority, then the SNMP/WEB card, then the shutdown command at the DCE, R2E, RSE, and USE cards, and then finally the onboard RS-232 port gets the lowest priority.

3.2. Selecting Installation Position

Install the UPS in a proper environment to minimize the possibility of damage to the UPS and to extend the life of the UPS. Please follow these rules:

1. Keep at least 30 cm (12 inches) clearance from the rear panel of the UPS to the wall.

2. Do not block the air flow to the ventilation openings of the unit.

3. Ensure that the installation site is not excessively hot or moist.

4. Do not place the UPS in an environment near dust, corrosive or salty material, or flammable objects.

5. Do not expose the UPS to the outdoors.

● L11-N1、B-N1: the terminal for Bypass Input to provide the power source when the UPS is working under bypass mode

● L12-N1、R-S-T-N1 : the terminal for Utility Input to provide the power source

● when the UPS is working under Utility mode

G1: the terminal for UPS Input Ground

● L21、L23、N21、L22、N22: the terminals for UPS Output

● G2: the terminal for UPS Output Ground

Remarks:

1. The maximum current for each terminal is 30 Arms for 6 kVA, 50 Arms for 10 kVA.

2. If the UPS is a DIM (Dual Input) type whose Utility and Bypass Sources are the same, L11 and L12 must be shorted for the 1-phase input model, and B and R must be shorted for the 3-phase input model.

3. If the UPS is a SIM (Single Input) type, only AC source can be supplied to the

UPS from the L12-N1 terminal for the 1-phase input model and from the R-S-

T-N1 terminal for the 3-phase input model.

4. Use No. 6 AWG, 75 C minimum copper wire and 23 lb-in Torque force when connecting to terminal block

●

Use mounting cable ties to fix cables.

3.5. Installation and Operation

3.5.1. Start Up in Normal Mode

3.5.1.1. Open the terminal block cover on the rear panel. (Refer to 2.3.2.)

Before starting the installation make sure the grounding is connected properly.

3.5.1.2. Make sure the utility breaker and the UPS’ Utility breaker and

Bypass breaker are in the “Off” position.

3.5.1.3. Make sure the utility voltage matches the input voltage window of the UPS.

3.5.1.4. Connect the utility separately to the terminal blocks of the UPS’

Utility and Bypass inputs. Switch on the power breaker of the distribution panel and the breakers of the UPS’ Utility and Bypass inputs. Then the UPS will start up. Green LEDs and show that the Utility and Bypass inputs are normal. UPSs with parallel function enabled will display first figure A1, then figure A2, and then figure B. Otherwise the LCD will display figure A1 directly followed by figure B.

22

3.5.1.5. The UPS is in Bypass Mode now. It will proceed to self-test automatically. If no abnormal message appears then the prestartup of the UPS was successful and the charger starts to charge the batteries.

3.5.1.6. Press the UPS On Switch for approximately three seconds.

The Buzzer sounds twice and the LCD display changes from figure B to figure C.

C

3.5.1.7. The UPS is in self-test mode again. The LCD display will change from figure C to figure D, and the UPS will remain in battery mode for approximately four seconds. Then the display will change from figure E1 to figure F if the self-test was successful.

D

“test”

E1

“OK” in self-test

E2

“Fail” in self-test

23

F

“220 VAC” in Utility Input

3.5.1.8. If the self-test fails the LCD display will change from figure D to figure E2. Then an error code or error status will appear on the screen.

3.5.1.9. Your start-up operation of the UPS is complete now. Make sure the UPS is plugged into the wall receptacle for charging at least 8 hours and the batteries are fully charged before connecting the device to be protected.

3.5.2. Start-up in Battery Mode (Cold Start)

3.5.2.1. Make sure the UPS has at least one set (20 pcs) of batteries.

3.5.2.2. Push the UPS On Switch once for approximately 5 seconds to awaken the UPS. The buzzer will sound twice. The LCD display will change from figure A to figure G for approximately 15 seconds.

3.5.2.3. Press the UPS On Switch again for about three seconds until the LCD display changes from figure G to figure H. Then the UPS will be in self-test mode. The UPS may offer energy to the output in a minute, and the LCD displays figure I. In case of failure in pushing the UPS On Switch for 15 seconds, the UPS will automatically turn off. You must then repeat steps 3.5.2.1 to

3.5.2.3.

G

“Off”, which means the UPS pre-start was successful

H

Utility input is “0” and Utility Abnormal.

I

3.5.3. Check Measured Values and Figures detected by the UPS

3.5.3.1. If you would like to check the measured values and figures detected by the UPS use the scroll up and scroll down keys. When you scroll down the LCD will display figure C (Voltage from Utility Input)  figure I1 (Voltage from Bypass Input)  figure J (Frequency from Utility Input)  figure K (Frequency from

Bypass Input)  figure L (UPS Output Voltage)  figure M (UPS

Output Frequency)  figure N (UPS Output Load %)  figure O
