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 ACU must be grounded to the ship. For further
grounding information refer to the Installation manual.
Do not extend the cables beyond the lengths specified for the equipment. The cable between
the ACU and Above Deck Unit can be extended if it complies with the specified data
concerning cable losses etc.
Rx and Tx cables for the SAILOR 900 VSAT 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
The voltage range for the SAILOR 900 VSAT is 20 — 32 VDC. Note that the Above Deck Unit is
powered by the ACU.
If a 24 VDC power bus is not available, an external 115/230 VAC to 28 VDC power supply can
be used, for example a SAILOR 6080 Power Supply.
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!
