UPS Multi－Module Installation
The basic installation procedure of a parallel system comprising of two or more UPS modules is the same as that of single module system. The following sections introduce the installation procedures specified to the parallel system.
3.10.1 Cabinet installation
Connect all the UPSes needed to be put into parallel system as below picture.
Make sure each UPS input breaker is in “off” position and there is no any output from each
UPS connected. Battery groups can be connected separately or in parallel, which means the system itself provides both separate battery and comman battery.
WARNING!
11
is well connected.
3.10.2 Parallel cable installation
Shielded and double insulated control cables available must be interconnected in a ring configuration between UPS modules as shown below. The parallel control board is mounted on each UPS module. The ring configuration ensures high reliability of the control.
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 rating and be connected to the same source.
12
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.
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 AC Mains and supplies DC power to 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 activated 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 electrical 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 critical, 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, then the
LCD shows all related information on the screen.
◆Parallel redundancy mode (system expansion)
To achieve a higher capacity and / or increase reliability, the outputs 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.
13
◆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 this manual bypass switch bears for equivalent rated load.
4.2 Turn on/off UPS
4.2.1
Restart procedure
CAUTION!
MAKE SURE GROUNDING IS PROPERLY DONE!
◆ Set the Battery Breaker to the “ON” position according to the user’s manual.
◆ Open the front and rear doors of the UPS to access to the main power switches. During this procedure the output terminals will become alive.
CAUTION！
Check to see if the load is safely connected 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
◆ UPS Input Switch(below the UPS module at the front door)
If the Rectifier input is within voltage range, the rectifier will start up in 30 seconds then the inverter will start up after then.
◆ UPS Output Switch(below the UPS module at the front door)
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
14
extinguishes and the inverter LED lights up.
