1.4 Assembly advice
Control units
The reverse side of the control unit has recesses that are used to lock the fastening rail which is fixed to the wall or
the aquarium cabinet with the screw set . The cable to the control unit has a USB connector so that holes of control
unit dimensions do not need to be sawn out of the terrarium cabinet . The USB connector is not designed for a compu-
ter connection . The control unit has a 2 metre cable which permits installation outside the aquarium cabinet as well
as an unobstructed view of all values and status modes .
