    Parallel (OPTIONAL) UPS in parallel configuration 7.1.1 Introduction UPS’s with parallel option fitted may be connected in a parallel configuration to increase both the reliability of the power supply to the load and the available output power. Up to 8 UPS’s can be parallel-connected. It is recommended to connect units of the same power.

  • Page 64: Electrical System Set-Up

    Electrical system set-up If the UPS’s are required to be configured as “parallel” units in field, the operation requires to install and connect one parallel card and one parallel signal card inside the unit. Read the instructions carefully before carrying out installation. All maintenance operations inside the UPS must be carried out only by trained personnel.

    UPS in parallel, as depicted in the diagram below. Note: MASTER HP-UL series have input terminals (for acquiring the status of aux contacts) galvanically isolated from the internal circuits of the UPS. This will result in to be sufficient a single aux contact electrical connection of the External switch brought to each UPS of the parallel system.

  • Page 66: Mains, And Load Connections

    The auxiliary contacts of SWOUT EXT and SWMB EXT must be connected to terminal J1 on the board 9AB2145 (aux signals insulation). The purpose of this board is to galvanically isolate the internal circuits of UPS, so that, in case of parallel of UPS, one auxiliary contact of the external switch is sufficient to be acquired by all the UPS in parallel.

  • Page 67: Connection Of Signals

    The length of cables rule of thumb must also be followed with separate mains power lines: the lengths of the cables of the bypass line + output line must be the same between all the UPS connected in parallel. Lack of compliance with this rule of thumb may cause a current imbalance between the UPS’s when the load is powered through the bypass line.

    Maintenance The uninterruptible power system is designed and produced to last a long time, even in the most severe service conditions. It should be remembered however that this is electronic power equipment, which requires routine maintenance. Moreover, some components have a limited lifespan and as such must be periodically checked and replaced should conditions so dictate: in particular the batteries, the fans and in some cases the electrolytic capacitors.
