B. The 5 wires from the cable are VW+, VW-, Thermistor (Temperature)+, Thermistor (Temperature)- and
Ground. Please refer to the sensor datasheet to identify the purpose of the stripped wires.
C. Untighten the gland cover, insert cable through the gland, then connect the 5 wires correspondingly as
shown in the Figure below.
D. Once the wires are connected, please tighten the gland cover firmly to ensure its IP rating on that channel.
Figure 4. VW Sensor Connections (VW+, VW-, T+, T-, GND).
Notice 1: The cable gland diameter of the 1-VW Interface Node is 8mm.
Notice 2: All the 5 wires must be connected, to minimise electrical interference and possible loss of precision.
Notice 3: Within any electrically noisy environment, nodes with sensors must be >= 0.3m away from the source of
the noise.
6) Power On: Once all the VW sensors are connected, turn the switch on. Now you should be able to see 3 LEDs
flashing 3 times, that means the node is on properly. Then switch off the node to save power if the gateway is off;
7) Tighten the 4 Cap-Hex-Head screws of the lid to secure the enclosure IP rating;
8) To validate the sensor data, please visit WISENMESHNET

5.4.Mounting Options
VW Interface Node can be deployed with various methods. However, the priciple is to make sure it is firmly attached to
the installation surface.
