Parallel Operation A parallel system may be designed by connecting outputs of multiple uninterruptible power supplies to a common load switch A parallel system will safely supply loads that are overly sensitive against electric power outages In a parallel system when any of UPSs malfunction and become offline other UPSs continue to supply the load thereby preventing any interruption with supply to load UPSs operating in parallel system share the load equally This way UPS life will be prolonged as each UPS operates under maximum capacity and UPS failures are reduced This minimizes loss of time and money In case where all UPSs in a parallel system malfunction UPSs will transfer the load automatically to static bypass lines and UPSs will activate again as soon as recovered from malfunction 8 1 Installation All electrical connections of all UPSs constituting parallel system must be provided as explained in Installation section of this user manual Note following warnings while installing a parallel system Installing and commissioning a parallel system should be carried out by authorized technical service personnel only e Parallel cables should be maximum 20 meters in length Nevertheless shorter cables ensure safer operation e Use a separate designated grounding cable for each UPS in parallel system e Use a separate designated battery group for each UPS e All UPSs in parallel system must be of same model and power
