CAUTION While the UPS is in Normal Mode operation, pressing the Standby/ Manual Bypass button once will put the UPS into Bypass Mode. Once the UPS is in Bypass Mode operation, press the Standby/ Manual Bypass button two distinct times (for about one second each time) to turn off the UPS.
Controls and Indicators 5.8 AC INPUT INDICATOR LED (GREEN) The AC Input indicator LED is illuminated when utility power is available and within the input specifications. 5.9 OUTPUT VOLTAGE SELECTION The Output Voltage is user configurable and is designed to allow selecting or changing the desired output voltage to match the utility via the GXT 2U Configuration Program provided with the UPS. The settings to choose from are 100, 110, 115, 120, and 127 VAC output. The factory default setting is 120 VAC.
Operating Instructions 6.0 OPERATING INSTRUCTIONS 6.1 NORMAL MODE OPERATION During normal operation, utility power provides energy to the UPS. The filters, power factor correction circuit and the inverter process this power to provide computer AC INPUT BATTERY UPS ON BYPASS grade power to connected loads. The UPS maintains Normal Mode Operation at 26-50% the batteries in a fully charged state. The four green load level LEDs indicate an approximate level of load in 25% increments.
Operating Instructions 6.3 BATTERY MODE OPERATION Battery mode occurs in event of an extreme input voltage condition or complete utility failure. The battery system supplies power through the DC to DC converter to the inverter to generate power for the connected load. AC INPUT BATTERY UPS ON BYPASS Battery Mode Operation at 80-61% During battery mode an alarm sounds every 10 seconds.
Communications 7.0 COMMUNICATIONS 7.1 COMMUNICATIONS INTERFACE PORT The UPStation GXT 2U UPS has a standard DB-9 serial port female connector located on the rear of the UPS unit.
Communications 7.2 PINS 4 & 5 - REMOTE SHUTDOWN ON BATTERY 1. This pin is functional only when the UPS is in battery mode. If the UPS is being powered by the utility, Pin 4 will ignore any signal on this pin. 2. Pin 4 requires a 5-12 VDC signal to shutdown. This normally comes form the serial port using Liebert’s contact closure cable. It cannot be used with just a contact closure unless the relay is used to switch a voltage source. A 5-12 VDC signal for 1.
Communications 7.3 PINS 5 & 6 - ANY-MODE SHUTDOWN 1. Pin 6 of the 9-pin communication connector is used for “Any-Mode Shutdown” of the UPS output.
