5.2
INSTALLATION OF POWER
CONTROL UNIT
Power control unit NQE-3167 is used when an antenna and a transmitter-receiver
are installed at a location away from the bridge, such as a foremast.
In the case of a two-unit type antenna, the maximum length of the cable that
connects between the display unit and the antenna is 65 meters. In the case of a
three-unit type antenna, the maximum length of the cable that connects between
the display unit and the transmitter-receiver is 35 meters.
By using NQE-3167 power control unit, the maximum length of the cable that
connects between the display unit and the antenna (transmitter-receiver) can be
extended up to 400 meters.
5.2.1 Connection with NKE-2103 type and NKE-2254-6HS type
scanners
Use 19-core composite cable CFQ-6912-** for the installation of those types of
antennas (Asterisks ** use the cable length, and the available cable length is 5, 10,
20, 30, 40, 50, and 65)
The display-unit side end of this cable is a metal shell round connector. （ See
Section 2.1.1CFQ-6912-**
）
Connect that cable to J2 of the power control unit.
If the metal shell round connector is cut, connect the cable to TB3 located in the
power control unit. For procedures for processing the cable end, see Section
2.1.4Cable end processing method.
With regard to six devices, such as MOTOR+(2P), MOTOR-(2P), 1A(+48V), and
2A(48VG), two AWG16 cables must be connected to one terminal block. As
necessary, use a bar-mould crimp-type terminal or the like. (See Fig 5-14:
Connection of CFQ-6912)
Maximum length of the cable connecting between the
antenna and the transmitter-receiver:
30m
Maximum length of the cable connecting between the
transmitter-receiver and the display unit:
35m
Maximum length of the cable connecting between the
display unit and the antenna (transmitter- receiver):
400m
