Installation 2.6 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. Thus, this guide applies equally to the input cable and output cable for this Elgar instrument and application loads.
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). 2.
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 Conductors Current Capability 3 to 6 80% Above 6 70% 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).
SECTION 3 OPERATION 3.1 Introduction This section provides detailed information on the controls and indicators, input/output connections, start-up and shutdown sequences, battery operation, and the RS-232 data communications port. 3.2 Control and Indicator Panel All controls and indicators for the GUPS 2400A-107 are located on the front panel of the unit. There are no operator adjustments inside the unit. Refer to Figure 3–1 for the location of the controls and indicators listed below.
Operation TEMP A two-color LED that indicates an over-temperature condition within the GUPS. The LED is green under normal operating conditions and red when an over-temperature shutdown occurs. TEST A two-color LED that indicates the results of the internal self-test. The LED blinks while a selftest is in progress. When the test is complete, the LED turns green if the test is passed and red it the test is failed. Figure 3–1.
Operation 3.2.2 Pushbutton Switches OUTPUT ON A momentary pushbutton switch on the front panel that alternately turns the output power on and off. TEST A momentary push button switch on the front panel that initiates the internal self-test. ALARM SILENCE A momentary pushbutton switch on the front panel that silences the audible alarm. 3.3 Circuit Breaker The AC input breaker is located on the front panel below the Control and Indicator Panel.
Operation If SHUTDOWN is asserted while the AC input is not present and the inverter is running from the battery, the output relay will open and output power will be turned off; the inverter and control circuits will also be shut down. After shutdown, the OUTPUT ON switch must be manually toggled to turn the output back on. RS-232 TRANSMIT/RECEIVE RS-232 transmit and receive for data communications. Refer to Section 3.9 for more information on RS-232 interface.
Operation 3.7 Start-Up and Shutdown Sequences To run the GUPS 2400A-107 from an AC input, perform the following steps: 1. Turn on the AC input circuit breaker located on the front panel. 2. 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. 3.
Operation 3. 3.8.1 To turn OFF the output, press the OUTPUT ON switch again; the switch has a alternating ON/OFF action. The unit will shut down (with no AC input present); the inverter and all control circuits will turn off. Battery Care and Handling The battery used in the GUPS 2400A-107 requires proper storage and recharging to maintain reliability. During storage, the self-discharge of the battery results in a sulfate coating that builds up on the plates.
