3. Thread the transducer cables through the cable fittings. To simplify cable
management inside the enclosure, wire transducer cables sequentially.
4. Insert the conductors of each cable into the terminal blocks of the MCN by
pressing down on the orange tab at the back of the terminal block, inserting
the conductor, and then releasing the orange tab. See Section 4.2.2 for
information on determining the correct wiring.
5. Pull gently on each conductor to ensure it is secure.
6. Tighten the nuts on the cable fittings. This must be done to ensure that
water does not enter the enclosure. Avoid overtightening as this may
damage the plastic threads.
7. Pull gently on the sensor cable to ensure it is held in place by the cable
gland.
8. Reinstall the cover. Ensure that the rubber gasket is properly seated in the
groove on the underside of the cover. Tighten the screws a little at a time,
working in a diagonal pattern; this ensures that the cover seals correctly.

TABLE 6: Standard Single Gauge Wiring

To determine the correct wiring for
wire gauges, refer to the wiring chart(s) in the manual provided with the
instrument. These types of instruments will require the use of more than one
channel in the MCN.
Supervisors, single channel nodes, and addressable nodes must be grounded
through the mounting hardware for maximum protection.

4.3 CONNECTING TO THE NETWORK

An MCN can be added to a network at any time; it will be detected and used
automatically if the network is already in deployment mode.
