Electrical connection

The electrical connection of the VVX is via a 5-pin plug M12x1 mounted on the cover of the
electronics housing.
CAUTION
The electrical connection should only be carried out by a fully qualified electrician.
 De-energize the electrical system before connecting the VVX.
IMPORTANT
Exceeding the specified limits will cause damage to the device's electronics. In
the absence of current limiting, there is a risk of fire due to device overheating.
 Always connect the VVX to an electrical source with power limitation.
Optional wiring
All VVX are configured to allow one flow output (frequency or analogue) to be wired as stand-
ard.
Depending upon the selected configuration, an optional temperature output, alarm output or
analogue output may also be wired.
Connection cable
Matching connection cables with female connector M12x1 are available in a various lengths
as SIKA accessories. Shielded connection cables are not necessary.
The connection cable should be fixed near the sensor. This can counteract a negative influ-
ence on the measurement result in case of strong vibrations in the environment.
IMPORTANT
Observe the temperature resistance of the connection cable at high media tem-
peratures.
If the maximum operating temperature is less than the media temperature, avoid
direct contact between the cable and the pipe.
Connection 5-pin plug M12x1
 Attach the female connector of the cable to the male connector of the VVX.
 Tighten the knurled nut of the female connector (do not exceed 1 Nm torque)
Earthing for VVX32 / VVX40
