Tripp Lite SU60K Operating Modes, Online Normal Mode Single UPS, Battery Backup Mode Single UPS

8 – Operating Modes

1

This section provides a basic description of the UPS system’s operating modes. For more information about switching between operating modes, refer to Section 9 – Start-Up, Shutdown and Bypass.

	8-1 Online (Normal) Mode (Single UPS)
	In online (normal) mode, the UPS system’s rectifier converts incoming
	AC utility power to DC power that charges the batteries and supplies the
3	inverter. The inverter transforms the DC power to precision-regulated,
	pure sine wave AC power that supports the operation of connected

CB3

equipment. This dual conversion technology isolates connected equipment from all power problems and ensures that connected equipment receives ideal power at all times.

8-2 Battery Backup Mode (Single UPS)

5When a blackout or other extreme power event occurs, the UPS system automatically switches from normal mode to battery backup mode. The UPS system’s batteries (internal and/or external) provide emergency

DC power to the inverter. The inverter transforms the DC power

6to precision-regulated, pure sine wave AC power that supports the operation of connected equipment.

8-3 Auto Bypass Mode (Single UPS)

If the inverter malfunctions due to excessive temperature, overload,

8output short circuit, abnormal voltage or battery problems, the inverter will shut down. If the UPS system detects a bypass power source that conforms to normal parameters, then the UPS system automatically switches to auto bypass mode to continue supplying power to connected

equipment. When all problems are eliminated, the UPS system switches

9back to online (normal) mode automatically.

	8-4 Manual Bypass Mode (Single UPS)
	If UPS system maintenance or repair is required, you can bypass the
	UPS system and enable bypass power manually. After confirming that
11	bypass power is present, switch the UPS system into manual bypass
	mode. This allows service technicians to perform maintenance or repair
	jobs without interrupting the flow of AC power to connected equipment.
	Warning: The UPS system must be de-energized completely before	MAIN
	performing maintenance or repair by shutting it down completely
12	after switching it to manual bypass mode.
