The following points need to be considered during installation of the IDU
•
All IDU components (ACU+Modem) should be mounted in a professional 19" server rack. For the
installation, operation and maintenance enough space should be available at the front and also some
space must be allowed behind the unit for the cables.
•
Proper cooling and ventilation is required for all IDUs. The ACU should be stored within a temperature
range of -40°C to 85°C. During operation, the ambient temperature must be maintained between -20°C to
55°C.
•
Fresh air intake is from the front of the ACU, and warm air is dispensed out the back. Therefore, Both
front and back panel of the ACU must be kept clear to allow ventilation. Otherwise, overheating might
cause system shutdown.
•
Either the UPS is provided by EPAK or a compatible UPS (on-line/double-conversion type) has to be
installed by the ship owner for powering the IDU.
4.8 Power supply for VSAT system
The ACU requires 90-264V AC @47-63 Hz, 1 phase. However, as the power supplied by vessel generators
can fluctuate considerably, an online type UPS is compulsory for EPAK VSAT system otherwise the warranty
becomes void. The ACU supplies the ODU with 48V DC power and the BUC with either 24V or 48V
depending on the model. There is also a switched AC outlet at the back of the ACU which can be used for the
modem’s power supply.
By default the ACU is equipped with a 2.5A fuse. This is suitable for operation with 230V. A spare 5.0A fuse is
provided alongside the ACU, which should be used instead, in the rare case that the antenna system should
be operated with 110V.
Caution: Grounding of the equipment is necessary to avoid potential differences between the ship’s
ground potential and the equipment’s. The antenna’s ground connection can be connected directly to
the ship’s ground to avoid undesired current flow.
