SECTION 2.7: INSTALLING CONTROL/MONITOR
WIRING
This section describes how to route wiring associated with the remote control and monitoring of the
NX5/NX3 transmitter.
Planning Complete?
1. Make sure you have read and fully understood the control and monitoring options described in the
NX5/NX3 Pre-installation Manual
before proceeding.
2. Make sure the control/monitor wires are long enough to allow routing through the top of the
transmitter cabinet and down to the exciter panel.
Routing Cables
1. Route all remote control/monitor cables to the top of the transmitter. Two possible entry holes are
provided to accept control/monitor wiring (see
Figure 2.7.2 on page 2.7.3 ).
2. Punch the appropriate size hole in the desired control/monitor entry plate as follows (see
Figure 2.7.2 on page 2.7.3 ):
– Remove the left-hand or right-hand entry plate from the top of the transmitter. Each is secured
using two M4 screws and has a pre-cut, centered 1/4-inch diameter hole.
– Use a chassis punch tool (e.g., Greenlee, etc.) to punch the desired size hole in the entry plate.
Make sure the control/monitor cables will pass safely through the hole. If necessary, you can
remove the plate completely to gain access to a smaller, rectangular hole.
– Install a conduit termination on the entry plate, if desired.
– Re-install the entry plate on top of the transmitter using two M4 screws.
3. Obtain two ferrite toroids (one each of Nautel Part # LXP38 and LXP44) from the ancillary kit.
4. Pass all control/monitor cables through the ferrite toroids obtained in Step 2 . If practical, wires
should pass through a minimum of two times (two turns) (see Figure 2.7.3 on page 2.7.3 ). Position
the ferrite toroids just outside, or just inside, the selected entry hole.
5. Route the control/monitor cables through the selected entry hole and toward the control/ interface
PWB (A4) on the exciter panel (see
Figure 2.7.4 on page 2.7.4 ). Route all wiring from the top of the
cabinet to the hinged side of the exciter panel to allow the panel to open.
