NV20LT/NV15LT INSTALLATION MANUAL INSTALLING CONTROL/MONITOR WIRING

SECTION 2.8: INSTALLING CONTROL/MONITOR
WIRING
This section describes how to route wiring associated with the remote control and monitoring of the
NV20LT/NV15LT transmitter.
Planning Complete?
1. Make sure you have read and fully understood the control and monitoring options described in the
NV20LT/NV15LT 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 rear panel of the controller (A4) or optional remote interface
PWB (A16) at the top, front of the transmitter.
3. If you ordered the optional Remote Interface PWB Kit, make sure it is installed (see “Installing the
Remote Interface PWB” on page 2.3.6 ). The transmitter is factory configured without the remote
interface PWB.
NOTE
: The transmitter’s factory configuration allows for remote interfacing with connectors on the rear
of the controller (A4). If you installed the optional remote interface PWB (A16) (see Figure 2.8.2 on page
2.8.4 ), you can interface with connectors on the remote interface PWB, which is located behind the
front, hinged UI panel.
Routing Cables
1. Route all remote control/monitor cables to the top of the transmitter.
2. Get two ferrite toroids (Nautel Part # LXP38, 19 mm inner diameter) from the ancillary kit.
3. Pass all remote control and 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 2.8.1 ).
 If remote control/monitor wiring is being routed to the rear of the controller (A4), use the
entrance hole at the top, rear of the transmitter (same hole as program input cable entry).
 If remote control/monitor wiring is being routed to the optional remote interface PWB (A16),
use the entrance hole at the top, front, right-hand side of the transmitter.
 Position the ferrite toroids near the transmitter cabinet - on top or inside.
