1.3.2 Powering On the Thermal Management Unit
NOTE: Depending on the operating state, there are start and stop priority switches that may prevent the cooling unit
from operating even though power to the unit is switched on and you have turned it on via Vertiv™ Liebert® iCOM™.
The cooling unit operates only when all switches are closed. For example, even though you have turned on the unit
through Liebert® iCOM™, if the BMS remote monitoring system is sending a command to turn off the unit, the cooling
unit remains off.
NOTE: You must be logged in to access the menu options. See Powering On the Vertiv™ Liebert® iCOM™ and Logging
In/Unlocking Controls on the previous page .
