2 Safety Recommendations & Precautions
2.1 Radar interference
•
The antenna must be mounted as far away as possible from the ship’s radar and high power radio
transmitters as they can affect the antenna performance. To avoid the worst interference, the antenna
should be mounted at a different vertical level – either 15° above or 15° below the radar. Kindly note
the recommended minimum distances between the ODU and X-band/S-Band radars in the table
4.2.3.
•
After the installation is completed all other electronic systems, i.e. GPS, Radar, VHF, FM, AM etc.,
should be tested for full functionality while the antenna is switched on.
2.2 Exposure to rain / moisture
•
Do not open sealed electronic components on the ODU and the ACU. Doing that will void the
warranty of the equipment.
•
The ACU and the UPS must always be kept indoors. Exposure to rain, sunlight or moisture may
damage the equipment.
2.3 Necessity of grounding the equipment
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 shall be connected directly to the ship’s ground to
avoid undesired current flow. For details refer to paragraph 4.9 Grounding.
2.4 Power supply
The ACU requires 90-264V AC @ 47-63 Hz Input voltage & frequency. The ACU then supplies DC power to
the Antenna. Use of an online UPS is mandatory for EPAK systems, otherwise the warranty becomes void.
For more details see 4.8.
2.5 Maintain ambient temperature for IDU
Proper cooling and ventilation is required for all indoor equipment. The ACU can be stored at a temperature
between -40°C to 85°C. During operation, the ambient temperature must be maintained between -20°C to
55°C. Frequent imbalances in the environment can damage the IDU electronics.
2.6 Maintain ambient temperature for ODU
Operating temperature for the ODU ranges from -20°C to 55°C, while the storage temperature range is
between -30°C to 85°C. When temperatures fall below -30°C, the antenna system must be kept on to avoid
damage to electronic parts at re-start. Alternatively an antenna heating system should be used.
