Overview – User Interface Caution 990-2282A-001 The display provides access to more functions than described in this manual. Those functions should not be accessed without the assistance of APC Customer Support in order to avoid unwanted load impacts. For APC World-Wide Customer Support, refer to the back cover of this manual. If you by accident get beyond the functions described, press ESC to return to previous screens.
Operation Operation Modes The UPS has different operation modes. If the installation includes a Maintenance Bypass Panel (MBP), an external maintenance bypass operation mode will also be available. Normal operation The UPS converts utility/mains power to conditioned power for the connected load. Battery operation The UPS provides power to the connected load from its internal and (if available) external batteries for a finite period.
Operation Procedures How to turn into bypass Single System – turning into internal bypass. The load is not protected by the UPS and the power is not conditioned when the internal mechanical bypass lever is activated. Caution In bypass operation the batteries are still charged. If a total power off is required, the batteries must be pulled out to the red disconnect line, see the section How to perform a total power off.
Operation – Operation Procedures Turn the internal mechanical bypass lever upwards to activate it. The load will now be supported directly by utility/mains power. Reinstall the Front Panel. Single System – turning into external bypass. In bypass operation the batteries are still powered. If a total power off is required the batteries must be pulled out to the red disconnect line, see the section How to perform a total power off.
Operation – Operation Procedures Parallel System – turning into external bypass. P In bypass operation the batteries are still charged. If a total power off is required, the batteries must be pulled out to the red disconnect line, see the section How to perform a total power off.
Operation – Operation Procedures How to turn into normal operation Single System – turning into normal operation from internal bypass. Never attempt to switch back the UPS into normal operation till you have verified that there are no internal UPS faults. Caution Check that the UPS is in bypass. The green (LOAD ON) and the yellow (BYPASS) LEDs are lit. Press ESC to return to the previous menus and turn out of bypass from the display via Control–UPS out of bypass–Yes, UPS out of bypass.
Operation – Operation Procedures Parallel System – turning into normal operation from external bypass. Never attempt to turn the UPS into normal operation till you have verified that there are no internal UPS faults. Caution From the external MBP: Turn all input switches (Q001) to position “1” (ON). From the external MBP: Turn all output switches (Q002) to position “1” (ON). The lamp indicator of the output isolation breaker (Q004) is still lit.
Operation – Operation Procedures How to turn load OFF/ON via the display interface Warning Disconnecting the UPS output to the load does NOT de-energize the UPS! Always follow the total power off procedure if you need to de-energize the UPS in emergency situations, see section How to perform a total power off! Turn Load OFF – How to disconnect the UPS output to the load equipment.

Operation – Operation Procedures How to perform a total power off Total power off – single system without MBP. Mains breaker UPS XR Enclosure Check that the load is OFF. From the UPS: Turn OFF the UPS from the display via Control–Turn Load Off –Yes, Turn Load Off. From the XR Enclosure(s) (if available): Set the DC disconnect switch to the OFF position.
Operation – Operation Procedures For details on how to remove Battery Locks (if available) see the section How to remove and install battery locks (if available). Total power off – single system with MBP. Check that the load is OFF. From the UPS: Turn load OFF the UPS from the display via Control–Turn Load off–Yes, turn Load off. From the external MBP: Turn the output switch (Q002) to position “0” (OFF).
Operation – Operation Procedures Total power off – isolating one UPS in a parallel system. From the UPS: From the Main Menu screen select Status and scroll down to Status of actual redundancy: n+ in order to check that the remaining UPS(s) will be able to carry the load when one UPS is isolated. From the UPS: Turn load OFF from the display on the UPS to be isolated via Control–Turn Load off–Yes, turn Load off.
Operation – Operation Procedures How to perform a restart Restart – single system wihout external MBP. Only trained personnel familiar with the construction and the equipment may restart the UPS. Warning Set the utility/mains breaker to the ON position. If your installation includes an XR Battery Enclosure (SUVTBXR2B6S/SUVTBXR6B6S) with a DC disconnect switch, set the DC disconnect switch to the ON position. Wait approximately 30 seconds for the system to boot up and carry out a self test.
Operation – Operation Procedures Auto-detection on frequency – if a problem occurs call APC Customer Support (see the back cover of this manual). Note Restart – single system with MBP. Only trained personnel familiar with the construction and the equipment may restart the UPS. Warning From the XR Enclosure(s) (if available): Connect the batteries by pushing them in. From the XR Enclosure(s) (if available): Set the DC disconnect switch (if available) to the ON position.
Operation – Operation Procedures Restart – parallel system. Only trained personnel familiar with the construction and the equipment may restart the UPS system. Warning From the XR Enclosure(s) (if available): Connect the batteries on the UPS units by pushing them in. From the XR Enclosure(s) (if available): Set the DC disconnect switch (if available) to the ON position. From the external MBP: Turn all output switches (Q002) to position “1” (ON).
