UPS INSTALLATION PLAN AND UNPACKINGEaton Power Xpert 9395P-1200 UPS (1200 kVA, 1200 kW) Installation and Operation Manual P-164000500 Rev 4 www.eaton.com/powerquality3-323.2.5 Distributed Bypass Power Wiring PreparationNOTE For full-rated operation of a Distributed Bypass System when in Bypass or ESS mode, the linefrequency impedance of all conduction paths must be equal when assessed from the point where the BypassPower Source connects to the System Switchgear to the point where the Common Load connects to theSystem Switchgear.Read and understand the following notes while planning and performing theinstallation: All distributed bypass UPS rectifier inputs must come from one source and allbypass input feeds must come from one source. All UPSs in the distributed bypass system must contain the same number ofUPMs. Mixed UPS kVA ratings are not permitted. Distributed bypass UPS input wiring size requirements and output wiring sizerequirements from the UPSs to the tie cabinet or distribution panel are the same aslisted in Table 3‐5, Table 3-5, Table 3‐7, or Table 3‐8. The Eaton 9395P-1200 480V unit is designed for operation on a grounded-wyesource of supply. There is no additional connection point for a neutral conductor.The output of this UPS will not directly support phase to neutral loads. The tie cabinet must contain Module Output Breakers (MOBs) with dual auxiliarycontacts for control of the system. Without dual auxiliary MOBs, UPMs are notallowed to go to bypass individually during servicing. All UPMs will go to bypassinstead of just the UPM needing service, decreasing critical load protection. Withdual auxiliary MOBs, one UPM can be bypassed while the remaining UPMssupport the load as long as the remaining UPMs have the capacity to do so. MOBswith dual auxiliary contacts are to be provided by the customer.3.3 Inspecting and Unpacking the UPS CabinetsThe UPS cabinet is divided into two sections palleted separately for shipping. Thesections are shipped bolted to wooden pallets (see Figure 3‐13 and Figure 3‐14) andprotected with outer protective packaging material.W A R N I N GThe UPS sections are heavy (see Table 3‐1). If unpacking and unloading instructions are not closely followed,the cabinets may tip and cause serious injury.A V E R T I S S E M E N T !Les sections de l’onduleur sont lourdes (voir le Table 3‐1). Suivre attentivement les instructions dedéchargement et de déballage pour éviter de renverser les armoires, ce qui pourrait causer de gravesblessures.
