3.10.3 Requirement for the parallel system

A group of paralleled modules behave as one large UPS system but with the advantage of presenting higher reliability. In order to assure that all modules are equally utilized and comply with relevant wiring rules, please follow the requirements below:

1) All UPS modules must be of the same rat ing and be connected to the same bypass source.

2) The outputs of all the UPS modules must be connected to a common output bus.

3) The length and specification of power cables including the bypass input cables and the UPS

output cables should be the same. This facilitates load sharing when operating in bypass mode.

3.11 Computer access

◆One end of a USB cable connect to the computer, the other end connect to the USB port on

the UPS.

◆Open the software Muser4000, click “system ” button .

◆A window of “Software Parameter Setting” comes out as below, COM choose according to the

Page 14

4．Operation

4.1 Operation Modes

The UPS is a double-conversion on-line UPS that may operate in the following alternative

modes：

◆Normal mode The rectifier/charger derives power from the A C Mai ns and supplies DC power t o the inverter

while floating and boosting charge the battery simultaneously. Then, the inverter converts the DC power to AC and supplies to the load.

◆Battery mode (Stored Energy Mode) If the AC mains input power fails, the inverter, which obtains power from the battery, supplies the

critical AC load. There is no power interruption to the critical load. The UPS will automatically return to Normal Mode when AC recovers.

◆Bypass mode

If the inverter is out of order, or if overload occurs, the static transfer switch will be act ivated to transfer the load from the inverter supply to bypass supply without interruption to the critical load. In the event that the inverter output is not synchronized with the bypass AC source, the static switch will perform a transfer of the load from the inverter to the bypass with power interruption to the critical AC load. This is to avoid paralleling of unsynchronized AC sources. This interruption is programmable but typically set to be less than an electr ical cycle e.g. less than 15ms (50Hz) or less than 13.33ms (60Hz).

◆ECO Mode

When the UPS is at AC Mode and the requirement to the load is not cr it ic a l, the UPS can be set at ECO mode in order to increase the efficiency of the power supplied. At ECO mode, the UPS works at Line-interactive mode, so the UPS will transfer to bypass supply. When the AC is out of set window, the UPS will transfer from bypass to Inverter and supplies power from the battery, the n the LCD shows all related information on the screen.

◆Parallel redundancy mode (system expansion) To achieve a higher capacity and / or increase reliability, the o utputs of up to four UPS modules

can be programmed to operate in parallel and the built-in parallel controller in each UPS ensures automatic load sharing.

◆Maintenance mode (Manual Bypass)

A manual bypass switch is available to ensure continuity of supply to the critical load when the

UPS is out of order or in repair, and t his manual bypass swit ch bears for equivalent rated load.

Page 15

4.2 Turn on/off UPS

4.2.1 Restart procedure

CAUTION! Make sure grounding is prorerly done!

◆ Set the Battery Breaker to the “ON” positio n according to the user’s manual.

◆Shut OFF the power breaker.

CAUTION！

Check to see if the load is safely c onnected with the output of the UPS. If the load is not ready to receive power from the UPS, make sure that it is safely isolated from the UPS output terminals

◆ Switch ON UPS input switch

If the Rectifier input is within voltage range, the rectifier will start up in 30 seconds then

the inverter will start up after then.

◆ Switch ON UPS output switch

If the recetifier fails at startup, the bypass LED will light up. When the inverter starts up, the UPS will transfer from bypass mode to inverter mode, then the bypass LED extinguishes and the inverter LED lights up.

No matter whether the UPS can work normally or not, all the status will be shown on the LCD display.

4.6 Options

SNMP card: internal SNMP / external SNMP optional

◆ Loosen the 2 torque screws ( on each side of the card).

◆ Carefully pull out the card. Reverse the proc edure f or re-installation

The slot called SNMP supports the MEGAtec protocol. We advise that NetAgent II-3 port is

also a tool to remotely monitor and manage any UPS system

NetAgent II-3Ports supports the Modem Dial-in(PPP) function to enable the remote control

via the internet when the network is unavailable .

In addition to the features of a standard NetAgent Mini, NetAgent II has the option to add NetFeeler Lite to detect temperature, humidity, smoke and security sensors. Thus, making NetAgent II a versatile management tool. NetAgent II also supports multiple languages and is setup for web-based auto language detection .

Typical topology of the UPS Network Management

Relay card

The card is used for providing the interface for UPS peripheral monitoring. The contact signals can reflect UPS running status. The card is connected to peripheral monitoring devices via DB9 female to facilitate the effective monitoring of the real-time status of UPS and timely feedback the status to monitor when abnormal situation occurs (such as UJPS failure, mains interruption, UPS bypass and ect.). It is installed in the intelligent slot of the UPS.

The relay card includes 6 output ports and one input port. Please refer to the following table for detail.

DB9 interface: Connect to upper control terminal. The definition of the pins is defined as
