6.2.3 Transmitter Connection
General
The wall mount enclosure is equipped with cable glands and dummy plugs
which have been installed or added as spare parts for replacement purposes.
Transmitter Type NivuSonic CO:
2 glands M20 x 1.5
2 dummy plugs M20 x 1.5
1 gland M16 x 1.5
2 dummy plugs M16 x 1.5
Using the accompanying cable glands the following outer cable dimensions can
be reliably connected:
M16 x 1.5 3.5 mm – 10.5 mm
M20 x 1.5 6.0 mm – 14.0 mm
To be able to use cable diameters outside of the tolerance, glands must be used
which ensure IP 65 minimum protection.
Unused wire lead-ins have to be locked with an appropriate dummy plug before
the initial start-up.
The transmitter clamp terminals ensure a safe connection of single- and multi-
wired cables with cross-sectional dimensions of 0.18-2.5 mm².
Due to reasons of better handling the flow velocity sensors are connected using
plug connections.
The pre-configured NIVUS sensor cable ends or single- as well as multi wired
cables with cross-sectional dimensions of 0.18-2.5 mm² can be connected to
these plug connections.
The 7-pole plug connections of the flow velocity sensors can be interchanged. It
however is impossible to interchange 7-pole and 9-pole plug rail (9-poles = flow
velocity sensor or adapter box connection) due to mechanic construction.
For connection to terminal clamps use a flat-bladed screwdriver with a blade
width of 3.0 mm or 3.5 mm. To connect the sensors to the plugs use a flat-
bladed screwdriver with a blade width of 2.0 mm or 2.5 mm.
The terminal clamps are normally unscrewed on delivery. Nevertheless this must
be checked before connecting the power supply or the signal wires.
Before the first connection it is necessary to have a slight pressure on the
screw of the clamping connection to ensure safe opening and proper contact-
ing.
Please use the supplied lid and both accompanying screws to lock the termi-
nal clamp housing in a way that protects water or dirt from leaking into the
enclosure and to ensure that the unit protection rating according to DIN EN
60529 will be preserved.
