DWM 2000 IP68
The version IP68 is supplied as a sealed unit, with all calibration
carried out before delivery. The customer has to be aware in
particular that the cable packing gland must not be opened as it
is specially sealed according to regulations.
Ensure to install the unit onto the flowpipe before connecting the
cable, as the cable needs to be free during the rotation of the
unit. The unit must be installed with the flow arrow marked on
the top of the housing aligned with the flow in the pipe.
For the wiring of the versions IP68, see the two diagrams below,
showing the two options of a common or separate power sup-
plies. The numbering corresponds to the following wire colours:
11 - Brown; 12 - Red; 5 - Orange; 6 - Yellow
For all electrical information refer to DWM2000 Technical Data
