Fastening antenna unit to the mounting platform

WARNING

Do not open the equipment unless totally familiar with electrical circuits and service manual.

Only qualified personnel should work inside the equipment.

Wear a hard hat and safety belt when mounting the antenna unit.

Serious injury or death can result if someone falls from the radar antenna mast.

Construct a suitable service platform from which to install the antenna unit.

Serious injury or death can result if someone falls from the radar antenna mast.

Note: The antenna unit is made of cast aluminum, which is subject to electrolytic corrosion if the mounting platform is steel or iron. To prevent electrolytic corrosion, use the supplied seal washers and corrosion-proof rubber mat.

Fix the antenna unit to the mounting location, referring to the procedure below and the illustration on the next page.

1.Referring to the antenna unit outline drawing, prepare a mounting platform at the mounting location for the antenna unit.

2.Lay the corrosion-proof rubber mat (supplied) on the mounting platform, aligning the holes on the rubber mat with the fixing holes on the mounting platform.

3.Lay the antenna unit on the rubber mat, orienting it so the cable gland is directed toward ship's bow.

4.Use hex bolts (M12×60), nuts, flat washers and seal washers to fix the antenna unit to the mounting platform.

5.Arrange the ground point at a location on the mounting platform that is within 300 mm from the ground terminal on the antenna unit. Fasten the ground wire (RW-4747, 340 mm) there, using the M6×25 hex bolt, nut and washers.

6.Connect the other end of the ground wire to the ground terminal on the antenna unit.

7.Coat the ground terminal, ground point on the mounting platform and fixing bolts on the antenna unit with anticorrosive sealant (supplied).
