4.            SAFETY CAUTIONS - NOTE WELL!

4.1         Batteries can present a risk of electric shock or burn from high short circuit currents. Always
              observe the proper safety precautions.

4.2         The UPS contains its own energy source so the output receptacles may carry live voltage even
              when the UPS is not connected to an AC supply.

4.3        Do not remove or unplug the input cord when the UPS is turned on as this removes the safety
             ground from the UPS and the equipment connected to the UPS.

5.          STACKING

5.1        The cabinets may be stacked vertically or horizontally. Do not stack more than three battery
             cabinets in one stack. In vertical stacks the UPS cabinet MUST be placed on the top of the stack.

5.2       Make sure the circuit breaker on all battery cabinets is OFF.

5.3       Connect the battery cable from the first Battery Cabinet into the UPS Cabinet.
             Then connect the battery cable from the second Battery Cabinet into the first, then the third into
             the second, etc.

5.4        Turn the circuit breaker on all the Battery Cabinets to the ON position.

6.          START UP VOLTAGE CHECK

6.1        Plug the UPS power supply cord into the input connector on the UPS rear panel.

6.2        Plug the other end of the UPS power supply into a grounded, three-wire, AC receptacle that has
             been wired in accordance with IEC specifications.

             NOTE :          Steps 6.3 through 6.6 are for changing the output voltage. The output voltage is
                                    factory-configured for 230V. check it is correct. If you do not need to change the
                                    output voltage, skip to step 6.7.

6.3        Press the Output OFF button until the alarm beeps.

              All indicators flash simultaneously.

6.4        Press and hold the Output | On button until the alarm beeps again.

              Two indicators, corresponding with the current setting, remain flashing. The output voltage is
              factory-configured for 230V.

6.5         Press the Output OFF button to scroll through the output voltage options, top to bottom. Each time
               you press the button, the UPS beeps and the next two indicators flash.

    NOTE :         If you do not save a selection within two minutes, the setup automatically aborts
                           and switches back to the original configuration.

6.6         Press and hold the Output | On button until the alarm beeps to select and save the output
               voltage. Failure to release the button immediately after beep will cause the UPS to abort the
              setup.

7.           INITIAL COMMUNICATIONS SETTING

7.1         Before you access the front panel, review the following configurations in Figure 15, and note
              the indicator that corresponds with the communications mode required.
              For Orderly Shutdown:- Printer Mode
              For Power Fail Recovery:- AS/400-Style LAN Contacts, No Serial

7.2        Press and hold the Output Off button until the long bleep ceases (approx three seconds)

7.3        Disconnect the mains input power, and wait until all indicators extinguish.

7.4        Reconnect the mains input power whilst holding the Output Off button, until the alarm beeps.
              All indicators will begin to flash.

7.5        Press and hold the Output Off button a second time until the alarm beeps again.

7.6        A single indicator, corresponding to the current setting will remain flashing.

7.7        Press the Output Off button to scroll through the communications options, top to bottom. Each
             time you press the button, the UPS will bleep and the next indicator will flash.
             NOTE :     If you do not save a selection within two minutes, the setup automatically aborts
                               and switches back to the original configuration.

7.8        Press and hold the Output | On button until the alarm beeps to select and save a
             communications option. Failure to release the button immediately after beep will cause the
             UPS to abort the setup.

             Press the Output | On button again to return the UPS to Normal Mode.

8.          EQUIPMENT CONNECTION

8.1        On the UPS press and hold the Output Off button until the UPS switches off its output and the
             lamps are extinguished. The equipment to be protected by the UPS should also be powered off.
             Plug the equipment into the power outlet receptacles on the UPS rear panel. Connect the
             appropriate UPS communications cable from the UPS to the system comms port
             Cable Type JM for Orderly Shutdown using Lansafe III See FECO LVC # 9
             Cable to be advised for Power Fail Recovery using PowerMon II Ver 3.3 See FECO LVC # 10.

8.2        DO NOT protect laser printers with the UPS because of the exceptionally high power requirements
             of the heating elements. The optional PowerPass has a surge-protected receptacle for laser printers.

8.3        Turn on the equipment that is connected to the UPS.

8.4        Press and hold the Output | On button until you hear the UPS beep (approximately one second).

8.5        The ~ Indicator remains lit and the Self Test Indicator turns on. The front panel displays the
             percentage of full load being applied to the UPS. The UPS is now in Normal Mode with the load
             online.

8.6        The UPS is initially shipped with the battery charged, however it may lose some of its charge
             during shipping and storing. Upon initial start up the UPS may need to operate for approximately
             8 hours before the battery is fully charged and full back up time is available. If the Battery Fault
             Indicator flashes, operate the UPS for 24 hours to fully charge the battery.
