SECTION 2.8: INSTALLING CONTROL/MONITOR
WIRING
This section describes how to route wiring associated with the remote control and monitoring of the
GV20/GV15 transmitter.
Planning Complete?
1. Make sure you have read and fully understood the control and monitoring options described in the
GV20/GV15 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 remote interface PWB (A16) at the top, front of the
transmitter or to the rear panel of the controller (A4).
NOTE
: The remote interface PWB (A16) is the recommended method of remote interfacing.
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 remote interface PWB (A16)
(recommended), use the entrance hole at the top, front, right-hand side of the transmitter.
 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).
 Position the ferrite toroids near the transmitter cabinet - on top or inside.
