Power Supply
Turn off the power at the mains switchboard before
beginning of the installation.
Confirm the power voltage is compatible with voltage
rating of the equipment. It is highly recommended to use
+24V DC power line, provided that it is available on the
vessel.
In case of unavailability of +24V DC power line provided
by the vessel, an external AC/DC power supply of
115/230V AC with its output of +24V DC can be used.
Note: The requirements of the AC/DC power supply
should take care of high surge current of 25A at 24V
DC for 1ms.
Grounding, cables and
connections
The chassis of the equipment must be connected to an
electrical ground. This will minimise electric shock and
mutual interference. In short, the EQUIPMENT must be
grounded to the vessel.
Service
Do not attempt to access to the interior of the equipment.
Only qualified personnel authorized by its manufacturer
may perform service. Failure to comply with this rule will
result in the warranty void.
Under certain conditions, dangerous voltages may exist
even with the power cable removed. To avoid injuries,
always disconnect power before accessing the
equipment.
Equipment Ventilation
To ensure adequate cooling of the terminal, 5-centimeter of unobstructed space must be
maintained around all sides of the unit except the bottom side. The ambient temperature range
of the transceiver is: -25°C to +55°C.
Fire Precautions
The equipment shall not be operated in the presence of flammable gases or fumes as well as
any explosive atmosphere. Operation of any electrical equipment in such an environment
constitutes a definite safety hazard.
