Cobham SATCOM.
Grounding, cables and connections
To minimize shock hazard and to protect against lightning, the equipment chassis and
cabinet must be connected to an electrical ground. The BDU must be grounded to the
ship. For further grounding information see the respective sections and appendix in this
manual.
Do not extend the cables beyond the lengths specified for the equipment. The cable
between the BDU and Above Deck Unit can be extended if it complies with the specified
data concerning cable losses etc.
Rx and Tx cables for the system are shielded and should not be affected by magnetic
fields. However, try to avoid running cables parallel to high power and AC/RF wiring as it
might cause malfunction of the equipment.
Power supply
SAILOR 7516A BDU: Voltage range 100-240 VAC. The ADU is powered by the BDU.
SAILOR 7023A GMU: Voltage range 100-240 VAC.
Do not operate in an explosive atmosphere
Do not operate the equipment in the presence of flammable gases or fumes. Operation of
any electrical equipment in such an environment constitutes a definite safety hazard.
Keep away from live circuits
Operating personnel must not remove equipment covers. Component replacement and
internal adjustment must be made by qualified maintenance personnel. Do not replace
components with the power cable connected. Under certain conditions, dangerous
voltages may exist even with the power cable removed. To avoid injuries, always
disconnect power and discharge circuits before touching them.
Failure to comply with the rules above will void the warranty!
