Unpacking the equipment

On receiving your BUC system, check the contents against the packing list. Make sure 
that all equipment itemised on the packing list is present and that there is no damage to 
the equipment before you start installing the equipment.

If anything is missing or damaged, please contact your nearest Codan office immediately 
to obtain the correct warranty service procedures. This ensures prompt assistance, 
minimal turnaround time, and avoids any freight issues.

We recommend that the equipment is installed by qualified and experienced personnel, 
to the relevant standards and approvals.

Installing the BUC equipment

For information on electromagnetic compatibility requirements and safety notices, 
please see the reference manual for the product.

WARNING

All equipment that is mounted outdoors 

must

 be adequately 

weatherproofed.

Use self-amalgamating tape to seal connectors and cable entry points, 
from the connector to the cable sheath (see 

Application Note: Sealing 

N-type and MS connectors in satellite equipment installations

, 17-60094).

Ensure all W/G joints are properly sealed with the appropriate gasket (see 

Application Note: Waveguide gasket kits

, 17-60128).

CAUTION

Water is the most common cause of poor performance in VSAT 
installations. Ensure that all cables and W/G junctions are properly sealed.

WARNING

A radiation hazard exists if the BUC is operated with its RF output 
unterminated.

WARNING

The BUC must be installed in a restricted access location with appropriate 
warning signs displayed.

CAUTION

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