2.2.4 Cable connections
Cable dimension of connections: 4.5…10 mm.
Tightening torque: 4 Nm
Please note:
If ULTRAFLOW® 54 is mounted with a galvanically coupled output
module, or if a galvanically separated output module is used in combination with
battery supply the unused cable connection must be sealed off as shown in Figure
12.
2.2.5 Change of supply unit
The supply unit of ULTRAFLOW® 54 can be changed from mains supply to battery
or visa versa as the needs of the supply company change. Thus, it can be an
advantage to change mains supplied meters to battery meters in buildings under
construction where the mains supply can be unstable or periodically missing.
Please note that the supply type of some ULTRAFLOW® sensors appears from the
label. If the original supply type is changed, it will no longer be in accordance with
the label.
