Symbols used WARNING: Indicates an electrical hazard, which, if not avoided, could result in injury or death. Caution: Indicates a hazard, which, if not avoided, could result in injury or death. Note: Indicates important information. See: Indicates that more information is available on this subject. Parallel System Summary The Parallel System Summary screen is the home screen in parallel systems. It provides you with an overview of the parallel system and circuit breakers.
UPS Summary Screen Single System In single systems, the UPS Summary screen is the home screen. It provides you with an overview of the UPS system and circuit breakers. It shows the system status and the power flow through the system and gives access to the system’s summary screens and the UPS System screen. A. Access further details on the current screen. B. Go to the UPS System screen. C. Go to the System Status screen for the current UPS. D. Go to the Bypass Summary screens. E.
Operation Modes UPS Modes The UPS operation mode is indicated in the top right corner of the screen under the heading UPS Mode. The UPS mode indicates the current status of the operated UPS. Normal Operation During normal operation, the UPS supports the critical load with conditioned power. While the UPS is operating in normal operation, a single-line diagram will appear on the screen. A green line indicates the power flow from the utility/mains, through the UPS system, and to the load.
Battery operation If the utility/mains supply fails, the UPS transfers to battery operation. During battery operation, battery power ensures uninterrupted support to the critical load. While the UPS system is in battery operation, a single-line diagram will appear on the screen. The green line indicates the power flow from the batteries, through the inverters, and then to the load.
Requested static bypass operation/forced static bypass operation The UPS is in requested static bypass following a command from the graphical user interface. And the UPS is in forced bypass when a fault on the system has caused static bypass operation. During static bypass operation, the critical load is supplied directly by utility/mains power. While the UPS is operating in this mode, a single-line diagram will appear on the screen.
Battery test The UPS is in battery test mode when the UPS is performing a battery self-test. During battery test, the battery runtime capacity is reduced by 10%. Note: The battery test will stop if the mains supply fails during the test.
System Modes The system mode is indicated in the top right corner of the screen under the heading System Mode. The system mode indicates the current output status of the complete system, and not the individual UPS unit. On When the system mode is On, the UPS system supports the critical load with conditioned power. The load is supported by the UPS in both normal and battery operation. Off When the system mode is Off, the UPS system does not support the connected load with power.
Maintenance bypass operation During maintenance bypass operation, the critical load is supplied directly by utility/mains power. While the UPS system is in maintenance bypass operation, a single-line diagram will appear on the screen. The orange line indicates the power flow from the utility/mains, and then to the critical load via the Q3 switch. Note: The batteries are not available as an alternate power source while the UPS system is in maintenance bypass operation.
Autostart Countdown The system can be set up for an automatic start when AC utility power is restored following a low battery voltage shutdown. The autostart countdown window is shown over all screens until the countdown period expires or the autostart is manually stopped by pressing the stop button. This feature is disabled by default and is not supported in parallel systems. Contact APC if this feature should be enabled.

Return Parts to APC Call APC Customer Support to obtain an RMA number. To return a failed module to APC, pack the module in the original shipping materials, and return it by insured, prepaid carrier. The APC Customer Support representative will provide the destination address. If you no longer have the original shipping materials, ask the representative about obtaining a new set. Pack the module properly to avoid damage in transit.
APC recommends that a whole battery module (one row of batteries) is replaced at the same time to ensure optimal run-time (see Example 1). However it may only be necessary to replace three battery units at the same time according to Examples 2 and 3 in the table below.
Replace Batteries Use two people to lift components weighing between 18–32 kg (40–70 lbs). 1. Holding the handle, gently lift the battery unit Battery Enclosure and pull it halfway out. A lock mechanism prevents it from being pulled all the way out. 2. Release the lock by pushing the battery unit upwards and pull the battery unit all the way out while you continue to support its weight. 3. Carefully guide the new battery unit into the system.
1. Identify the faulty power module via the display or the red LED indication in the top right corner of the power module. 2. Deactivate the power module by turning the locking latch counter-clockwise to the unlocked position. 3. Unscrew the spring-activated knobs on both sides of the power module. 4. Pull the power module up and out of the enclosure as far as the lock mechanism allows. 5.
9. Activate the power module by turning the locking latch clockwise to the locked position. The LED in the top right corner of the power module will start to flash (green) which indicates that the power module is initializing and doing a self test. When the self test is complete, the LED will be constant green.
Replace Boards in Input/Output/Bypass Enclosure WARNING: Only trained persons familiar with the construction and operation of the equipment, as well as the electrical and mechanical hazards involved, may install and remove system components. WARNING: Before replacing the boards, ensure that the “UPS system firmware version” and the “System firmware version stored at memory card” are identical on the System Information screen. WARNING: Replace only one board at a time.
Replace Boards in the Battery Enclosure WARNING: Only trained persons familiar with the construction and operation of the equipment, as well as the electrical and mechanical hazards involved, may install and remove system components.
