Chapter 1 Introduction A parallel system with up to three 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.
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 nutdriver 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 remove the UPS or EBM from the shipping pallet: 1. Remove the two M10 bolts securing the stabilizing bracket to the pallet (see Figure 2). M10 Bolts Figure 2.
UPS SETUP 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. Remove the three M10 bolts securing the rear shipping pad to the pallet and remove the shipping pad (see Figure 3). NOTE Hold the back of the cabinet so that the bolts can be removed easily without the cabinet rolling backward. 5.
UPS SETUP NOTE Be sure to support the front and back of the cabinet when rolling it off the pallet to prevent tipping. 7. Slowly roll the cabinet toward the rear of the pallet. Once the pallet tilts, continue rolling the cabinet down the pallet until the cabinet touches the floor (see Figure 4). If needed, adjust the leveling feet so that the cabinet will roll. Figure 4. Unloading the Cabinet 8. With the cabinet supported, slowly pull the pallet away from the cabinet (see Figure 5). Figure 5.

Chapter 10 Troubleshooting The Powerware 9155 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. If you have an optional Maintenance Bypass Module or Power Distribution Module, 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.
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 26). Set the system to internal Bypass mode (see page 53).
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.
