5. Operation Modes
Note:
1. Refer to
3. Operation Panel
for details on using the operation panel and understanding the display meaning.
2. Each of the display diagrams shown in this chapter is for reference only. Actual display depends on the UPS
operation.
5.1 Standby Mode
After the UPS is connected to the AC utility, it will supply power to the UPS and the batteries will be
charged. The default setting of the UPS is ‘STANDBY mode’.
5.2 On-line Mode
In on-line mode, the connected loads are supplied by the inverter, which derives its power from the
utility AC power. The UPS charges the batteries and provides power protection to its connected loads.
5.3 Bypass Mode
In bypass mode, the critical loads are directly supplied by the utility power and the batteries are charged.
5.4 Economy Mode
Economy mode refers to an optional UPS configuration for reduced power consumption and heat output.
A UPS in economy mode reduces power consumption by suspending the double conversion (AC-to-DC /
DC-to-AC) process whenever input power is already of high enough quality to pass through to connected
equipment unchanged. The UPS will automatically switch back to on-line mode if input power quality
deteriorates to ensure connected equipment receives high-quality power under all conditions.
5.5 Battery Mode
When the UPS is operating during a power outage, the batteries’ DC power is inverted to AC and
continues to provide power to the attached load(s) until a graceful shutdown can be completed.
Tripp Lite’s PowerAlert software is downloadable free of charge at www.tripplite.com/poweralert
to monitor remaining battery capacity before and during a power outage. An optional SNMP
card may be used to monitor and control the UPS across a network. Refer to
www.tripplite.com/products/power-management-software-hardware~10 for more details on
Tripp Lite’s SNMP management cards.
