Commissioning
Commissioning the cooling circuit
Once the modules have been installed in the plant, the coolant circuit must be commissioned
before the electrical systems.
Venting the heat sink
The heat sink does not have to be vented when filling the heatsink with integrated copper-
nickel alloy or stainless steel heat exchanger.
After connecting the device to the power supply and before switching on for the first time, the
cooling circuit should operate for approximately 30 min to ensure that coolant flows through
the device.
