NX400 Installation Manual Installing control/monitor wiring

Section 9: Installing control/monitor
wiring
This section describes how to route wiring associated with the remote control and monitoring of the
NX400 transmitter.
Planning complete?
1. Make sure you have read and fully understood the control and monitoring options described
in the NX400 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 control cabinet (cabinet 1). Two
possible entry holes are provided to accept audio input wiring (see Figure 9.3 on page 9-4 ).
2. Punch the appropriate size hole in the desired control/monitor entry plate as follows (see
Figure 9.3 on page 9-4 ):
– 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 # LXP44 and LXP38) from the ancillary kit.
4. Pass all remote control/monitor cables through the ferrite toroids obtained in Step 3 . If
practical, wires should pass through a minimum of two times (two turns) (see Figure 9.2 on
page 9-3 ). Position the ferrite toroids just outside, or just inside, the remote control/monitor
entry hole.
