3.8 Battery connection The UPS adopts positive and negative double battery framework, total 30(optional 32/34/36/38/40/42/44/46/48/50) in series. A neutral cable is retrieved from the joint between the cathode of the 15 ) and the anode of the 16 ) of the batteries. Then the neutral cable, the battery Positive and the battery negative are connected with the UPS respectively.
3.9 UPS parallel Installation The following sections introduce the installation procedures specified to the parallel system. 3.9.1 Cabinet installation Connect all the UPS 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.
3.9.3 Requirement for the parallel system A group of paralleled UPS behaves as one large UPS system but with the advantage of presenting higher reliability. In order to assure that all UPS are equally utilized and comply with relevant wiring rules, please follow the requirements below: 1) All UPS must be of the same rating and be connected to the same bypass source.

Single input Dual input ◆ 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.
Page 25
Dual input ◆ 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. 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.
Page 26
◆ 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.
Dual input 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. 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 ◆...
