DANGER
Life-threatening danger due to electric shock
Live units and exposed connection cables can generate an electric shock and cause severe accidents.
Work on electrical connections must be carried out exclusively by trained, qualified electricians.
Ensure that the unit is voltage-free before routing all electrical connections.
The service interface (1) can be used to change operating parameters. It is installed inside the DTT cooling unit,
so the unit cover must be removed for connection to the USB adapter.
Unit cover removal, see
The connection (1) for the USB adapter is provided on the controller circuit board. It is identified as X28 on the
electrical circuit diagram.
The blinking of the red LED light on the controller circuit board is not a fault indicator or error message. The red
LED light indicates that voltage is supplied to the cooling unit.
To change operating parameters, a USB adapter (2) and the ECoolPLANT 2.X configuration software and USB
driver software are required.
The USB adapter enables connection to a computer that works with the ECoolPLANT 2.X configuration
software. The detailed use is described in the corresponding operating manual for the ECoolPLANT 2.X
software.
Remove the USB adapter (2) from the unit after use. The service interface (1) is only provided for temporary
data exchange in order to read system notifications, etc. Continuous operation is prohibited.
The USB adapter is available as an accessory, see
The ECoolPLANT software (3) is available for download free of charge on the website:

The corresponding operating manual for the ECoolPLANT software is available HERE and from My
