UPS SYSTEM INSTALLATIONPower Xpert 9395 UPS (450–825 kVA) Installation and Operation Manual 164201725 Rev 9 www.eaton.com/powerquality4-184.5 Field Installed UPM InstallationIf installing a Plus 1 model or adding the FI-UPM to an 825/550 model, install theFI-UPM using the instructions in the Power Xpert 9395 Field Installed UPMMechanical Installation Manual, listed in paragraph 1.7. After the FI-UPM is installed,proceed to paragraph 4.6 if installing a battery system; otherwise, proceed toparagraph 4.7.4.6 Battery System InstallationIf installing a battery system, install the customer-supplied battery system accordingto the battery and battery system manufacturer's instructions and all applicable codesand regulations, including the NEC, Article 480. After the battery system is installed,proceed to paragraph 4.7 if installing a distributed bypass tie cabinet; otherwise,proceed to paragraph 4.8.4.7 Distributed Bypass Tie Cabinet InstallationNOTE The tie cabinet must contain Module Output Breakers (MOBs) with dual auxiliary contacts for controlof the system. Without dual auxiliary MOBs, UPMs are not allowed to go to bypass individually duringservicing. All UPMs will go to bypass instead of only the UPM needing service, decreasing critical loadprotection. With dual auxiliary MOBs, one UPM can be bypassed while the remaining UPMs support the loadas long as the remaining UPMs have the capacity to do so.If installing a distributed bypass system, install the customer-supplied tie cabinet ordistribution panel according to the tie cabinet or distribution panel manufacturer'sinstructions and all applicable codes and regulations, including the NEC, Article 480.After the tie cabinet is installed, proceed to paragraph 4.8 to complete the wiring ofthe UPS.In the case of parallel Distributed Bypass configurations, wiring for the commonsystem neutral reference will also be connected to E12 of each module and thiscommon system neutral reference wiring will be routed to the output switchgearcabinet and connected to an isolated / ungrounded bus which is common with thewiring from the E12 terminal of all other paralleled modules of the Distributed Bypasssystem.4.8 Installing UPS External and Battery Power WiringNOTE The ISBM and UPM sections are shipped with debris shields covering the ventilation grills on top ofthe sections (see Figure 4‐18). Do not remove the debris shields until installation is complete. However,remove the shields before operating the UPS. Once the debris shields are removed, do not place objects onthe ventilation grills.NOTE Remove the ISBM section top or bottom conduit landing plate to drill or punch conduit holes (seeFigure 4‐19).NOTE If the load requires a neutral, a bypass source neutral must be provided. If the load does not requirea neutral and there is no neutral conductor connected at the bypass input, a neutral to ground bonding jumpermust be installed. DO NOT install both a source neutral and a bonding jumper. See Table 3‐4 throughTable 3‐7 for neutral bonding jumper wire sizes. Bonding jumper must be copper wire.C A U T I O NHIGH IMPEDANCE GROUND SOURCES - If the supply source is a high impedance ground (IT) type, theneutral‐forming transformer kit must be used instead of pulling a neutral from the source. In nocircumstances shall a neutral to ground bonding jumper be installed in the UPS.
