5.12.3 Reuse Scenario

In reuse scenarios, the D.G. connects to the UPS over the bypass module. Dry contacts control
D.G. startup and shutdown.
Issue 10 (2015-09-15)

In battery mode (not battery test state), when the battery voltage reaches D.G. startup batt. volt. or
Low battery voltage, the UPS triggers D.G. startup signals.

In normal mode or bypass mode, if the mains is normal (the mains supplies power for 1 minute and
the D.G. runs for 15 minutes), the UPS triggers D.G. shutdown signals.
 If the battery voltage is greater than D.G. startup batt. volt., the UPS exits intelligent mode and
triggers D.G. shutdown signals. If the battery voltage is less than D.G. startup batt. volt., a dialog
box is displayed, indicating potential risks. Tap OK to exit intelligent mode.
 To disable the D.G. from the UPS system, set Intelligent Power Supply to Disabled. The system
changes Working mode to Normal mode, Intra-rack power unit start delay (s) to 5, Output freq.
track rate (Hz/s) to 0.6, Input adaptability to Non-strong input, D.G. mode to Disabled, and D.G.
connection [GEN] to Disabled. You can change the values.
