1. INSTALLATION AND WIRING
1.1 Mounting Considerations
Select a mounting location, keeping in mind the following points:
• Install the antenna unit on the hardtop, radar arch or on a mast on an appropriate
platform.
• Locate the antenna where there is a good all-round view. Where possible, there
should be no obstructions to the scanning beam such as superstructure or rigging.
Obstructions cause shadow sectors and decrease the overall performance of the
radar. The loss of performance can cause false echoes and reduce the quality of
the observed images. A mast for instance, with a diameter considerably less than
the horizontal beam width of the radiator, will cause only a small shadow sector.
However, a horizontal spreader, or cross trees in the same horizontal plane as the
antenna unit, would be a much more serious obstruction. You would need to place
the antenna unit well above or below it. Be sure there are no metallic objects near
the antenna.
• It is rarely possible to place the antenna unit where a completely clear view in all
directions is available. After fitting the antenna, determining any shadow sectors,
their angle and bearing, and their influence on the radar is recommended.
NOTICE
Do not apply paint, anti-corrosive sealant or contact
spray to coating or plastic parts of the equipment.
Those items contain organic solvents that can damage
coating and plastic parts, especially plastic connectors.

Vertical beam angle = 22°

1. INSTALLATION AND WIRING

• In order to reduce electrical interference, avoid routing the power cable near other
electrical equipment on-board. Also, avoid running the cable in parallel with other
power cables.
• It is not recommended to install the antenna unit on the hardtop of a cabin. Vibra-
tions from the antenna unit will pass through the hardtop and into the cabin.
• Setup the antenna unit position on the FURUNO Multi Function Display after install-
ing the unit, referring to the chapter 2. If the antenna unit position is not setup cor-
rectly, the radar echoes on the display may not be aligned with the actual target’s
bearing.
• Select a location that does not allow water to accumulate at the installation location.
• A magnetic compass will be affected if the antenna unit is too close to the compass.
Observe the compass safe distances mentioned in the SAFETY INSTRUCTIONS
to prevent interference to a magnetic compass.
• To ensure proper emission of radar waves, do not paint the radiator.
• Referring to the outline drawings at the back of this manual, allow space for main-
tenance and service.
• When this antenna unit is to be installed on a large vessel, consider the following
points:
• The supplied cable assembly runs between the antenna unit and display (or eth-
ernet HUB) and comes in lengths of 10 m, 15 m, 20 m or 30 m. Select the appro-
priate length when purchasing.
• Deposits and fumes from a funnel or other exhaust vent can adversely affect the
aerial performance and hot gases may distort the antenna unit. The antenna unit
must not be mounted where the temperature is more than 55°C (131°F).

diator bracket.
1.5 Mounting the Antenna Unit
The antenna unit can be mounted using the fixing holes on the outside (200 u200 mm)
or inside (140 u150 mm) the antenna unit. Normally, use the outside fixing holes.
When 140 u150 mm fixing holes already exist on the mounting platform, use the in-
side fixing holes.
1. Set the supplied mounting template to the mounting location, then drill four fixing
holes in the mounting location.
Note: The holes must be parallel with the fore and aft line.
2. Apply adhesive to the thread of the stud bolts (M12u70, 4 pcs).
Note: Apply adhesive to the part of the bolt threads that are inside the bolt hole
(see the figure at step 3).
3. Insert four stud bolts into the threaded holes in the antenna unit.
The stud bolts must make contact with the bottom of the threaded holes.
Note: Do NOT cover the vent hole at the bottom of the unit.

1.6 Wiring
Wiring considerations
• Turn the power at the switchboard off before beginning the wiring.
• For DRS6A X-Class, insert the 5 A fuse in the fuse holder. Attach the supplied fuse
rating label to the fuse holder. For details, see “How to Replace the Fuse” (C32-
01604).
• For DRS12A X-Class and DRS25A X-Class, insert the 10 A fuse in the fuse hold-
er. Also, attach the supplied fuse rating label to the fuse holder. For details, see
“How to Replace the Fuse” (C32-01604).
• The cable assembly and power/LAN cables have connector(s). Do NOT cut the ca-
ble assembly and power/LAN cables even if the cables are run through a radar
mast.
• When you replace the DRS4A/6A/12A/25A with the DRS6A X-Class/DRS12A X-
Class/DRS25A X-Class, the existing cable cannot be used. Use only the cable as-
sembly supplied with this radar sensor

• Red wire: Connect to the positive terminal. The red wire has the fuse holder.
• Blue wire: Connect to the negative terminal.
• Black wire: The black wire is a shielding wire for grounding.
Note 1: The antenna unit has no power switch. Connect the antenna unit to a dis-
tribution switchboard with a switch for power control.
Note 2: If the voltage of the ship’s battery is 12 VDC, prepare a DC-to-DC con-
verter whose output current is 10 A or more.
