20.3 Choosing the installation place
The NivuFlow with DIN rail fastening is conceived for installation in control cabinets.
Â
Ü
Make sure there is adequate ventilation at the installation place, such as fans or air slits.
Â
Ü
Make sure that any existing disconnectors (power switch) remain easily accessible during
installation.
The measurement transmitter can also be installed in field enclosures or similar. NivuFlow 650
is not suitable to be installed directly on site without protective measures due to protection
degree. To do so, use the optionally available field enclosure by NIVUS.
The following precautions should be taken to ensure safe installation at the installation
site:
Â
Ü
Protect the transmitter from direct sunlight. Install a sun shade if required.
Â
Ü
Avoid mounting the transmitter close to objects with strong electromagnetic fields (fre-
quency converters, high voltage powerlines or similar).
Â
Ü
Observe the permissible ambient temperature (see Sect. “16 Specifications”).
Â
Ü
Do not expose the transmitter to strong vibrations or mechanical shock.
At the mounting place always avoid:
• Corrosive chemicals or gases
• Radioactive radiation
20.4 Transmitter fastening on DIN rail in control cabinets
Assemble required materials beforehand
Mounting materials and tools are
not
part of the standard delivery.
Â
Ü
For fastening use a DIN rail type TS35 according to EN 50022 with a minimum length of
140 mm.
1. Fasten the rail horizontally in the intended enclosure/control cabinet by using at
least two screws.
2. Hook the transmitter into the DIN rail from below. The unit will snap in as soon as
you exert slight pressure in the direction of the DIN rail.
Now you can begin to install the electrical components and to connect the sensors.
