Chapter 1 Introduction A parallel system with up to four uninterruptible power supplies (UPSs) can be installed to provide a parallel capacity and/or redundant system. This load sharing system provides more capacity than a single UPS and can provide backup, depending on the load and configuration. In addition, when one UPS is taken out of service for maintenance or is not operating properly, a redundant UPS continues to supply uninterrupted power to the critical load.

Chapter 3 UPS Setup This chapter describes: S Equipment inspection S Floor loading and clearances S Unloading the cabinet(s) The instructions are intended for the chief operator/system supervisor, electrical consultants, and installation electricians. Local regulations and electrical code must be followed during the UPS installation.
UPS SETUP Floor Loading When planning the installation, consider the UPS weight for floor loading. The strength of the installation surface must be adequate for point and distributed loadings. The approximate weights are shown in the following table. Standard Model Floor Loadings (2-High/3-High Cabinets) Eaton 9355 UPS Maximum Weight Point Loading lb/in2 (kg/cm2) 2-High UPS 381 lb (173 kg) 95 (6.7) 3-High UPS-32 587 lb (266 kg) 147 (10.3) 3-High UPS-64 619 lb (281 kg) 155 (10.
UPS SETUP Unloading the Cabinet(s) The following tools are required for unloading the cabinet(s): S 15 mm wrench or socket S 7 mm nut driver or socket CAUTION The UPS and Extended Battery Module (EBM) are heavy (see page 8). Unloading the cabinets requires at least two people to safely remove the cabinets from the pallet. To unload three-high cabinets or two-high EBMs, continue to the following section. To unload two-high UPS cabinets, proceed to page 13.
UPS SETUP 2. Remove the four M4 screws securing the stabilizing bracket to the cabinet rear panel and remove the bracket (see Figure 3). Retain the hardware for later use. NOTE Retain the stabilizing bracket and hardware for later re-assembly onto the cabinet. 3. Remove the front cover from the bottom cabinet to access the front shipping bracket. Press and release the handle latch at the bottom of the cover and then lift the cover up and off the cabinet. 4.

Chapter 11 Troubleshooting The Eaton 9355 UPS is designed for durable, automatic operation and also alerts you whenever potential operating problems may occur. Usually the alarms shown by the control panel do not mean that the output power is affected. Instead, they are preventive alarms intended to alert the user. Use the following troubleshooting chart to determine the UPS alarm condition.
TROUBLESHOOTING Alarm or Condition Possible Cause Action Overtemperature UPS internal temperature is too high or the fan has failed. Turn the maintenance bypass switch to the SERVICE position. Otherwise, shut down the UPS. Clear vents and remove any heat sources. Allow the UPS to cool. Ensure the airflow around the UPS is not restricted. If the alarm disappears, turn the maintenance bypass switch back to the UPS position. If the condition persists, contact your service representative.
TROUBLESHOOTING Alarm or Condition Possible Cause Action Check Parallel Board The UPS is not recognizing another parallel unit. From the UPS Status menu, select the Units on CAN Bus option and verify that all UPSs appear in the list. If any UPS is missing, verify the Powerware Hot Sync® CAN Bridge Card connections and recheck the status from the UPS front panel. If all UPSs appear in the list, check the pull-chain wiring (see page 43). Set the system to internal Bypass mode (see page 65).
TROUBLESHOOTING Service and Support If you have any questions or problems with the UPS, call your Local Distributor or the Help Desk at one of the following telephone numbers and ask for a UPS technical representative.
