• When each slot is firmly hooked on the relevant bolt, tighten each bolt (use 15 mm spanner, torque
=46 Nm)
• Optional: sun cover kit - Insert the sun cover and tie one of its bottom holes to the ODU handle by
means of the black plastic strip included in the sun cover kit
• The ODU is ready to be connected to the grounding cable and to the Lan cable
Attention: Leave 25 cm straight Lan cable between Amphenol connector and first bending to secure water-
proof IPX5
8.9.1.2 1+1 ODU with separated antenna
See Fig.39.
• Position the supporting plate (1) on the pole and fix the rear bracket (2) to it by means of the four
130 mm M10 bolt (3) with relevant washers, springs and nuts (use 15 mm spanner, torque = 46
Nm)
• Move the marking reference, present on the twister disk, to H or V label of the hybrid flange (an-
tenna side), to set the polarization as shown in Fig.36
and tighten the four screws (torque value as
in Tab.21
)
• Mount the hybrid on the supporting plate (1), tightening four M10 bolts (5) with method cross (first
bolt on high left position, second bolt on opposite side following the diagonal, then do the same with
the other two bolts (see Fig.39
)
Mounting each ODU on the hybrid:
• Screw partially four 25 mm M10 bolts positioning them in the holes (7) on the hybrid flange (ODU
side): each bolt should be tightened to have the square head out of the hole of about 13-14 mm,
use 15 mm spanner
• Apply seal and lubricant grease Dow Corning 4 to the O-ring, protecting fingers with gloves, and
insert in the proper track on the ODU flange
• Position the ODU vertically near the four bolts on the antenna flange and align the ODU to match
the polarization of the antenna feeder: horizontal polarization must be used, the handle of the ODU
is at the bottom right corner
• After the right position has been found, rotate 30° counter clockwise the ODU and approach it to
the antenna flange in order to have the four slots of the Standard Lock cross between the four bolts
on the hybrid
• Rotate 30° clockwise the ODU to hook each slots on the relevant bolt
• When each slot is firmly hooked on the relevant bolt, tighten each bolt (use 15 mm spanner, torque
= 46 Nm)
• Optional: sun cover kit - insert the sun cover and tie one of its bottom holes to the ODU handle by
means of the black plastic strip included in the sun cover kit
• Now the ODU is ready to be connected to the grounding cable and to the Lan cable
• Repeat for the other ODU on the other side
Attention: Leave 25 cm straight Lan cable between Amphenol connector and first bending to secure water-
proof IPX5
8.9.1.3 Waveguide towards the antenna
After having installed the ODU in 1+0 configuration or in 1+1 configuration, the waveguide towards the
antenna must be installed.
• 1+0: the waveguide must be fixed to the antenna flange on the supporting plate of the ODU. In
case of flexible waveguides, an excessive folding can damage the waveguide, see Tab.22
for details.
• 1+1: the waveguide must be fixed to the hybrid. In case of flexible waveguides, an excessive folding
can damage the waveguide, see Tab.22
for details.
