executed before the unit has been disconnected from mains power in order to minimise
danger and ESD risks.
Disconnect the NivuFlow from mains power.
The sensitive electronic components inside the unit may get damaged by static electricity. The
manufacturer recommends the following steps to prevent the device from getting damaged due
to electrostatic discharge:
Â
Ü
Discharge static electricity from your body before touching the instrument’s electronic
components.
Â
Ü
Avoid unnecessary movements to reduce the risk of building up static electricity.
14.2 Choosing the installation place
The NivuFlow with DIN rail fastening is conceived for installation in switching cabinets.
