3.1 ODU INSTALLATION IN AN UNPROTECTED CONFIGURATION

3.1.1 ODU INSTALLATION – DIRECT MOUNT

Use the figures below as a guide to installing the ODU in an unprotected configuration:

Figure 2: Attach ODU onto antenna


HIPERION ODU Page 10

Figure 3: Latch locking buckles Adjust the antenna to the desired polarization (refer to Hiperion 0.3m_0.6m Antenna Installation

Manual and the Hiperion 1.2m Antenna Installation Manual for details).

Vertical polarization is indicated by an upward pointing arrow and the letter “V”, see figure 4. Horizontal polarization is with the ODU rotated 90° clockwise, see figure 5. Make sure the ODU polarization is consistent with antenna polarization.

Attach ODU onto antenna and hook each locking buckle. Latch each locking buckles. Verify the waveguide port on ODU is connected properly with the interface flange on the antenna

before tightening each lock buckle. A padlock or tie wires can be installed through the eye of the latch to ensure ODU security.



Figure 4: Vertical polarization

Figure 5: Horizontal polarization

3.1.2 ODU INSTALLATION – REMOTE MOUNT

In this instance, the ODU is attached to a Remote Mount Adaptor, and the adaptor connected to the antenna with a length of flexible Rectangular Waveguide (Flextwist). The Flextwist may come in a variety of lengths, depending on the frequency band of operation. Generally these lengths vary from 0.6m to 1.2 m. The ODU Remote Mount Adaptor must be located as close as possible to the antenna to allow the Flextwist be be installed without any strain on the rubber jacket or the flexible copper inner tube. Use the figures below as a guide to installing the ODU and ODU Remote Mount ODU in an unprotected configuration:



Figure 6: Lengths of Flextwist Waveguide.

Figure 7: Latch locking buckles



Attach the ODU to the ODU Remote Mount Adaptor hooking each locking buckle. Latch each locking buckles.

Attache the Flextwist to the ODU Remote Mount Adaptor using the provided gaskets and

fasteners. Attach the Flextwist to the flange on the antenna using the provided gaskets and fasteners.. A padlock or tie wires can be installed through the eye of the latch to ensure ODU security.

3.1.3 SURGE PROTECTOR INSTALLATION

A Surge Protector is provided to be connected on the ODU to achieve lightning protection. This surge protector is installed together with the grounding of ODU. Connect the surge protector at the “N – Type” connector “IF” interface of ODU. Fix the Ground Wire to the grounding terminal of theODU and the metal fasteners of the tower or mast. This wire must be as short as possible.

3.1.4 CONNECTING IF CABLE This refers to the connection between ODU and IDU. Before connecting the IF cable, ensure that the IDU is powered OFF. Locate and connect the IF cable to the N-type connector of the installed Surge Protector, and the other end of the IF cable goes to the Surge Protector mounted to the “IF” interface on the IDU.

3.1.5 WATERPROOFING MEASURES After all the screws, bolts and nuts are tightened, seal the surge protector assembly and connector of the IF cable using self vulcanising tape covered by a waterproof and UV resistant tape.

3.2 ODU INSTALLATION IN PROTECTED CONFIGURATION

3.2.1 ODU INSTALLATION Use the figures below as a guide to installing the ODU in the protected configuration:



Figure 8: Attach coupler to antenna

Figure 9: Latch locking buckles



Adjust the antenna to the desired polarization (refer to Hiperion 0.3m_0.6m Antenna Installation Manual and the Hiperion 1.2m Antenna Installation Manual for details).

Adjust the antenna to the desired polarization (refer to Hiperion 0.3m_0.6m Antenna Installation

Manual and the Hiperion 1.2m Antenna Installation Manual for details).

Adjust the coupler to the expected polarization (refer to ATLL-CB Redundancy Coupler for details). Make sure the coupler polarization is consistent with antenna polarization.

Vertical polarization is indicated by an upward pointing arrow and the letter “V” see figure 4. Horizontal polarization is with the ODU rotated 90° clockwise, see figure 5. Make sure the ODU polarization is consistent with antenna polarization.

Attach ODU onto antenna and hook each locking buckle. Latch each locking buckles. Verify the waveguide port on ODU is connected properly with the interface flange on the antenna

before tightening each lock buckle. A padlock or tie wires can be installed through the eye of the latch to ensure ODU security.

Figure 10: ODU installation in protected system



Attach one ODU to coupler and hook the locking buckles.

Verify the waveguide port on ODU is connected properly with the feed flange on coupler before

tightening each lock buckle. Follow steps above to install another ODU to coupler.

Figure 11: Installed ODU in protected system

3.2.2 SURGE PROTECTOR INSTALLATION

Figures below present the appearance of surge protector and right angle adaptor.

Figure 12: Surge protector



Figure 13: Right angle adaptor

When the 1+1 configuration is applied, a right angle adaptor can be used as the connector between the surge protector and IF cable to make the installation of surge protector easier. To install the right angle adaptor, connect one end to the ODU IF interface, while the other end goes to the surge protector. Each ODU should be equipped with a surge protector. Connect the surge protector at the “N – Type” connector “IF” interface of ODU. Fix the Ground Wire to the grounding terminal of theODU and the metal fasteners of the tower or mast. This wire must be as short as possible.

3.2.3 CONNECTING THE IF CABLES This refers to the connections between the ODU’s and the IDU’s. Before connecting the IF cable, ensure that the IDU’s are powered OFF. Locate and connect the IF cable to the N-type connector of the installed Surge Protector, and the other end of the IF cable goes to the Surge Protector mounted to the “IF” interface on the IDU.

3.2.4 WATERPROOFING MEASURES After all the screws, bolts and nuts are tightened, seal the surge protector assemblies and connectors of the IF cables using self vulcanising tape covered by a waterproof and UV resistant tape.

4 FINAL INSPECTION AFTER ODU INSTALLATION

When the installation of the ODU has been completed, make sure that the installation instructions have been followed. It’s especially important to check that all locking buckles are properly locked.

5 MAINTENANCE AFTER ODU INSTALLATION After equipment commissioning, no further maintenance by hand is required. After NMS commissioning, the monitoring centre can control the operational status of all of the equipment in the network. The following regular inspections are recommended to ensure long life system performance.



Antenna systems should be inspected once a year by qualified personnel to verify proper installation, maintenance, and the condition of equipment. This should include a comparassion of the RSL with the RSL as noted in the Commissioning Document. Note that for this comparassion, weather conditions should be similar to those at the time of installation.

The Station and System Earthings should be inspected every 12 months for integrity and low ground resistance.

Periodically check for proper connection and tightening of all cables and mounting fixtures. Make sure that the ATL Hiperion ODU has not been damaged, disassembled or otherwise tampered with.

Ensure that the ATL Hiperion ODU remains properly grounded as described in the previous sections.

Cleaning the surface of the equipment regularly to remove dust and other deposits like salt for exxample, to ensure the normal operation and prolonging the useful life of the equipment.

The Surge Arrestors are designed to be sacrificial. Inspect the Surge Arrestor devices for integrity. Replace any that do not meet electrical specifications or appear suspect on physical examination.

The installation location for ATL Hiperion ODU should remain well ventilated.

ATECIL disclaims any liability or responsibility for the results of improper or unsafe installation practices.

The ATL- ODU’s have no user serviceable parts internally. In the event of a hardware fault, the faulty unit must be replaced with a known functional unit and returned to ATECIL for repair.

NOTE: Information in this document may be subject to changes without notice.
