Powering On The Thermal Management Unit - Vertiv Liebert iCOM DP400/500 Installer/User Manual

1.3.2 Powering On the Thermal Management Unit

NOTE: Depending on the operating state, there are start/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 iCOM.
The cooling unit operates only when all switches are closed. For example, even though you have turned on the unit
through 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
on the previous page.

1. Touch
2. Touch Turn Unit On. The cooling unit starts and the operating status is displayed as shown in Figure 1.4 below.
