•Start-Up Procedure

Multiple UPS Operation (Parallel)

The diagrams and procedures in this section apply to a parallel configuration where multiple UPS Power Modules (up to eight) are connected to a single equipment load. A parallel configuration provides fail-safe redundancy, assuring that the load is constantly supported even if one or more UPS Systems fail or are taken off-line for maintenance. Two or more UPSs operating in parallel must have the same VA capacities, output voltage and frequency. They also must be able to assume an equal share of the equipment load in order to not overload the UPSs and switch all UPSs to Reserve AC Input Supply Mode.

Operational Modes

Normal Mode

In this mode, the power modules continuously convert AC input power into DC power (to recharge their batteries and supply their inverters). Their inverters, in turn, transform DC power into clean, stable AC output power for the connected equipment load.

For each UPS power module in the parallel configuration which will be placed on bypass, simultaneously press the “OFF” and “” Buttons and hold for 3 seconds. The power modules inverter will turn off its LCD Screen will display “Output Close” and support of the equipment load will be transferred and shared equally among the other UPS power modules in the parallel configuration that have not yet been placed on bypass. As each consecutive power modules inverter is turned off, however, a point will be reached where the power modules which have not yet been placed on bypass will not be able to share the combined load. At this point, the remaining power modules will automatically shut down their inverters, transfer the load to reserve power and display “Bypass Mode” on their LCD Screens Shutdown ProcedureManual Maintenance Bypass Procedure Other Information “Measure Page” Sub-Menu Measure Page Parameter Setting System Control Event LogMain Menu E F G H “Parameter Setting” Sub-MenuLCD Display Navigation continued A B C DA B C D LCD Display Navigation continued“System Control” Sub-Menu “Event Log” Sub-MenuUPS Status Code “Other Information” Sub-MenuDry-Contacts Remote Emergency Power Off EPO RS-232 Port/Ethernet Port/SNMP Card Slot Ethernet PowerCommunications continued GENERATOR CONTACTUPS Parallel Communication Port RS-485 PortTERMINAL RESISTOR FOR RS-485 RS-485 PortWarranty Registration LIMITED WARRANTY200503068 1111 W. 35th Street Chicago, IL 60609 USA
