  • Page 16: Wire Gauge Selection

    Installation Wire Gauge Selection The following guidelines assist in determining the optimum cable specification for the user's power applications. These guidelines are equally applicable to both DC and low frequency AC (up to 450 Hz) power cabling. The same engineering rules apply whether going into or out of an electrical device.
  • Page 17 Installation The following notes apply to Table 2–2 and to the power cable definition: 1. The above figures are based upon insulated copper conductors at 25°C (77°F), two current carrying conductors in the cable plus a safety (chassis) ground. Columns 3 and 4 refer to "one way" ohms and IR drop of current carrying conductors (e.g., a 50-foot cable contains 100 feet of current carrying conductor).
  • Page 18 Installation 5. Derate the above wire gauge (use a heavier gauge) for an increased number of current carrying conductors. This offsets the thermal rise of bundled conductors. Number of Current Conductors Capability 3 to 6 Above 6 6. The preferred insulation material is application dependent. Elgar recommends any flame retardant, heat resistant, moisture resistant thermoplastic insulation rated to a nominal 75°C (167°F).

    Operation TEST. A two-color LED that indicates the results of the internal self-test. The LED blinks while a self-test is in progress. When the test is complete, the LED turns green if the test is passed and red it the test is failed. 3.2.2 Pushbutton Switches OUTPUT ON.

  • Page 21: Circuit Breakers

    Operation Circuit Breakers AC INPUT The AC input breaker is located on the front panel below the Control and Indicator Panel. It is turned ON by pushing in the actuator button, and it is turned OFF by pulling out the actuator button.

  • Page 22: Connectors

    Operation OUTPUT CURRENT An AC voltage signal that is proportional to the AC output current. The output is 0.221V/A, or 4.6 VRMS at full load. This signal is transformer isolated from the other control signals. Connectors The GUPS 2400A–104 has cylindrical, metal-shell connectors with bayonet coupling for all input/output connections of power and signal.

  • Page 23: Start-Up And Shutdown Sequences

    Operation Start-Up and Shutdown Sequences To run the GUPS 2400A–104 from an AC input, perform the following steps: Turn on the AC input circuit breaker located on the front panel. Wait approximately 10 seconds for completion of the start-up routines. During this time, the GUPS performs a self-test to assure proper functionality, and the rectifier undergoes a soft-start so that current surges on the AC input are prevented.

  • Page 24: Battery Care And Handling

    Operation To turn OFF the output, press the OUTPUT ON switch again to use the alternating ON/OFF action of the switch. The unit will shut down (with no AC input present); the inverter and all control circuits will turn off. 3.8.1 Battery Care and Handling The battery used in the GUPS 2400A-104 requires proper storage and recharging to maintain...
