KVH Industries TracPhone FB250 Installation Manual page 6

Grounding, cables and connections
To minimize shock hazard, the equipment chassis and cabinet must be
connected to an electrical ground. The terminal must be grounded to the
ship. For further grounding information refer to Grounding and RF
protection on page 119.
Do not extend the cables beyond the lengths specified for the equipment.
The cable between the terminal and antenna can be extended if it complies
with the specified data concerning cable losses etc.
All cables for your TracPhone 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 voltage range is 10.5 - 32 V DC; 14 A - 5.5 A. It is recommended that the
voltage is provided by the 24 V DC power bus on the ship. Be aware of high
start-up peak current: 20 A at 24 V, 5 ms.
If a 24 V DC power bus is not available, an external 115/230 VAC to 24 V DC
power supply 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!
