7.8 Setup Operation
The Liebert AC4 operation features allow you to set up a rotation
sequence to alternate which devices are operating and which are
placed on Standby, as well as test devices while in Standby mode and
specify what to do when a Standby device goes into alarm as it is
powered up. You may also specify delay times after an output changes
state, directing the Liebert AC4 to wait before acknowledging inputs or
turning an output on or off.
