4. RC1815/RC1825 Equipment Installations
4.4 FS-1570/FS-2570 Installation
Refer to Installation Manual, FS-1570 (150W) / FS-2570 (250W)
4.4.1 Control Unit
1) The FS-2570C (Control Unit) and HS2001 (Handset) have been mounted and
wired into the console.
4.4.2 Transceiver Unit
1) The Transceiver is designed for bulkhead mounting using six tapping
screws or bolts. Select a location that can support the weight of the unit,
(FS-1570: 25 lbs., FS-2570: 31 lbs.), under the operating conditions encountered
onboard the ship. If necessary, reinforce the mounting location.
2) Connect the 24 VDC, Rear Connections: PR850A, to TB1(+) and TB2(-) of the
transceiver, through a set of inline breakers or fuses. When installing the power
cable in the transceiver, use a razor knife to cut an opening in the grommet.
The FS-1570, which draws 20 amps, will require an 8-gauge wire for up to
40 feet separation from the PR850A power supply.
The FS-2570, which draws 35 amps, will require a 6-gauge wire for up to
40 feet separation from the PR850A power supply.
3) Connect the cable Controller 1, connected to the FS-2570C, to the
transceiver port Controller 1.
4.4.3 Antenna
1) The antenna is to be provided by the Dealer. This antenna should be 7 to 30
meters in length and be mounted as clear of obstructions as possible. When
considering the mounting location of the antenna, be sure to allow space for
mounting the antenna coupler.
4.4.4 Antenna Coupler AT-1560-15 or AT-1560-25
1) Mount the antenna coupler as close to the antenna as possible. The provided
coupler can be mounted horizontally or vertically depending on the location.
(Refer to Pgs. 2-1 through 2-3 of the Installation Manual)
2) Connect the antenna wire from the antenna to the insulator at the top of the
coupler. Keeping the length as short as possible.
3) Fasten the supplied ground strap to the connection provided at the base of the
antenna coupler. Make certain this connection is brazed or welded to the ship's
hull or ground system. The exposed ground strap should be painted or coated with
a material to prevent rust.
