Cooling products that use power crossfeed can be powered on only after both power inputs
are connected.
Teamwork settings can be performed only after all cooling products in a group have been
powered on.
Air cooled smart cooling products include 21 kW and 25 kW models.
For the diagrams and tables, see the initial configuration parameter manual for the solution
in use.
Before the power-on commissioning, ensure that the air supply and return vents of cooling
products are not blocked.
The humidifier water refill and drainage work properly, and cooling product condensate
drainpipes are intact and not blocked.
If any alarm is raised, rectify the fault before continuing the commissioning.
Before power-on, clear dust, dirt, and foreign matter from the cabinet; otherwise, the water
pump may be blocked, resulting in drainage failure or serious equipment malfunction.
