2.2.3Display and Controls

2.2.3.1General

The UPS is provided with a microprocessor-based unit status and control display designed for convenient and reliable user operation. The status and alarm indicators are displayed on a status indicator display.

2.2.3.2System Indicators

There are three (3) status indicators on the front of the UPS (Utility, Battery and Fault) and one (1) on the rear (Site Wiring Fault):

The Utility Indicator illuminates when the UPS is operating and supplying power to connected loads: green indicates Normal mode, amber denotes Buck/Boost mode.

The Battery Indicator illuminates to indicate the UPS is operating on battery (green) or to signify a battery warning (amber).

The Fault Indicator illuminates when the UPS detects a problem: red for an internal UPS fault, green for overload and over-temperature conditions.

The Site Wiring Fault Indicator on the rear panel illuminates red when the UPS detects a line-neutral reversal or a poor neutral-ground bond.

2.2.3.3On/Off Controls

UPS start-up and shutdown operations are accomplished by the "On/Off/Alarm Silence" push button located on the front panel of the UPS. Depressing the button for more than 0.5 sec will start-up the UPS and to turn the UPS off the button will need to be depressed for more than 2 sec

2.2.3.4On-Line Battery Test

The UPS is provided with an automatic biweekly battery test feature. The test ensures the capability of the battery to supply power to the inverter while loaded. If the battery fails the test, the UPS will display a warning to indicate the batteries need replaced. The battery test feature is user accessible via Multilink.

2.2.4Internal Battery

Valve regulated, non-spillable, lead-acid cells are used as a stored-energy source for the specified UPS system. The battery is housed internal to the UPS cabinet, and sized to support the inverter at rated load and power factor, with ambient temperature of 77 o F (25 o C) for a minimum of 5 minutes reserve time. The expected life of the battery is 3 - 5 years or 250 complete discharge cycles.

2.2.5Output Distribution

Output distribution is integral to the UPS and is located on the rear of the unit.
