4. Pull gently on each conductor to ensure it is secure.
5. Tighten the cable gland nut until it firmly grips the outer jacket of the cable.
The cable gland nut must be properly tightened to prevent water entry. Do
not over-tighten, as this might strip the plastic threads.
6. Pull gently on the gauge cable to ensure it is held in place by the cable gland.
7. Repeat these steps for each gauge cable you need to connect.

To prevent a short circuit, do not allow bare leads to touch each other during or
after wiring.

3.5.2 MAKING 10-PIN CABLE CONNECTIONS

To connect a device using a 10-pin connection:
1. Remove the cover from the 10-pin connector.
2. Align the grooves on the sensor connector (male), with the connector on the
Node (female).
3. Push the connector into place and then twist the outer ring of the male
connector until it locks.

3.5.3 NOTES CONCERNING MULTI-CHANNEL AND ADDRESSABLE NODES

■
For ease of wiring, sensor cables should be inserted into the cable glands
on Multi-Channel Nodes from left to right.
■
Sensors should be wired into the channels of a Node in sequence starting
with channel 1.
■
Do not wire sensors into the terminal blocks marked '
a Multi-Channel Node.
■
Multi-Channel Nodes and Addressable Nodes stop trying to read an empty
channel after two attempts. The node will read all channels at the top of
every hour; it will resume sampling when it detects a sensor.
