Connect the ground wire for all ac power configurations to the inside threads of the
Station Reference Ground bolt (E1) at the back of the transmitter cabinet.
NOTE
Remote control/monitor wiring terminates
on the remote interface PWB (see Figure
2-2). The connectors (included in the
ancillary kit) are solder-cup type and the
terminal blocks accept wires sizes (AWG)
# 14 through # 24. Cabinet entry holes for
the control/ monitor cables are provided in
the top front of the cabinet. See Figure 2-8
or 2-9 for the exact cable entry location.
(a) Route wires through the cable entry
hole(s) to the remote interface PWB
(A44). Use Figure 2-7a (V10/V7.5) or
2-7b (V5/V3.5) to determine the
specific destination of each wire.
(b) Pass all control/monitor wires through
the ferrite toroid(s) installed in the
transmitter (see Figure 2-2). If
practical, pass the wires through each
toroid a minimum of two turns.
(c) Determine which remote control
inputs are being applied and then
determine if they are differential or
single-ended input. See 2.2.13
(Remote Control Circuits), for more
information on the type of input.
(d) Cut each wire to the required length
and, if the wire connects to a terminal
block, remove 3/8 inch (9.5 mm) of
insulation from the end of each wire; if
the wire connects to a pin connector,
remove approximately 1/8 inch (3.2
mm) of insulation from the end of
each wire.
(e) Insert the control/monitor wiring into
the terminals of the remote interface
PWB or solder them to the applicable
connector pin, as identified in Figure
2-7a (V10/V7.5) or 2-7b (V5/V3.5).
Ensure adjacent wires do not touch
(short) and the terminal block securing
screws are firmly tightened.
2.3.6 Installing Ac Power Source
Wiring
Connect the wiring between the ac power
source and the ac distribution assembly
(A1), noting it is located on the cabinet
floor (see Figures 2-2 and 2-3).
(a) Switch off the ac power at the service
entrance.
(b) Remove the lower rear filter panel.
Remove the cover from the ac
distribution assembly (A1) to access
these terminals. Leave the filter panel
off until installation is complete.
(c) Choose the most suitable ac cable
entry hole at the top or bottom of the
cabinet (see Figures 2-2, 2-8, 2-9).
NOTE
Install wiring in a metal conduit. Attach the
conduit to the cabinet at the entry hole.
When wiring is in a floor mounted trench
or the transmitter is on a pedestal, use the
hole at the bottom, rear of the cabinet.
(d) Get two ferrite toroids (Nautel Part #
LP23, 85.7 mm) from the ancillary kit.
