SAFETY SUMMARY
iii
Grounding, cables and connections
Grounding, cables and connections To minimize shock hazard, the equipment chassis and cabi-
net must be connected to an electrical ground. The Communication Unit must be grounded to the
ship. For further grounding information refer to this manual.
Do not extend the cables beyond the lengths specified for the equipment. The cable between the
Communication Unit and Antenna Unit can be extended if it complies with the specified data con-
cerning cable losses etc.
All cables for the FleetBroadband system are shielded and should not be affected by magnetic
fields. However, try to avoid running cables parallel to AC wiring as it might cause malfunction of
the equipment.
Power supply
The Communication Unit input voltage range is 12 - 24 VDC (-10%/+30%); 14 A - 5.5 A. Be aware
of high start-up peak current: <20 A@24 V, <5 ms.
If a DC power bus is not available, the optional AC/DC power supply unit can be used.
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!
