1. INSTALLATION AND WIRING
3
Consideration for selecting a location for installation (multiple radars)
• In case multiple radars are installed on a ship, DO NOT install the DRS6A-NXT/
DRS12A-NXT/DRS25A-NXT within the range of the beam area emitted from other
radar(s). Use the illustration below for reference when selecting a suitable location
for installation. The Solid State Device (SSD) inside the DRS6A-NXT/DRS12A-
NXT/DRS25A-NXT will be damaged if it is within the radar beam emission area from
other radars.
Installation with the radiotelephone equipment
• Install the open antenna away from radio communication antennas (SSB, VHF, In-
marsat) and GPS antennas to prevent radar interference.
• Install the open antenna away from the radiotelephone equipment so that electrical
noise does not affect the radiotelephone equipment.
Cable routing
• In order to reduce the chance of picking up electrical interference, avoid, where pos-
sible, routing the power/LAN cable and cable assembly near other electrical equip-
ment on-board. Also, avoid running the cable in parallel with other electrical cables.
• Make sure that the power/LAN cable does not run horizontally with the cable as-
sembly and it is placed away from the cables carrying radio signal and antennas.
For large vessels
• When this radar sensor is to be installed on a large vessel, consider the following
points:
• The length of the pre-attached power/LAN cable is 1 m from the open antenna to
the connector.
• Deposits and fumes from a funnel or other exhaust vent can adversely affect the
aerial performance and hot gases may distort the radiator portion. The radar sen-
sor must not be mounted where the temperature is more than 55°C (131°F).

Suitable location for installing the
DRS6A-NXT/DRS12A-NXT/DRS25A-NXT
Locate the radar out of the radar
beam (dark gray) of other radar.
