Step 1 - Installing the NAIS-400 AIS transceiver
Please note the following guidelines when selecting a location for
your AIS transceiver:
• The AIS transceiver must be fitted in a location where it is at least
0.5 m from a compass or any magnetic device.
• There should be adequate space around the AIS transceiver for rout-
ing of cables. See Figure 5 for details of the AIS transceiver dimen-
sions.
• The ambient temperature around the AIS transceiver should be
maintained between -25°C and +55°C.
• The AIS transceiver should not be located in a flammable or hazard-
ous atmosphere such as an engine room or near fuel tanks.
• The AIS transceiver is fully waterproof to ingress protection rating
IPx7. However, it is recommended that the AIS transceiver not be
subjected to extended periods of exposure to spray or submersion.
• It is acceptable to mount the AIS transceiver either vertically or
horizontally.
• It is recommended that the AIS transceiver is installed in a ‘below
deck’ environment.
• The product is supplied with four selftapping screws for attachment
of the AIS transceiver to a suitable surface. Please refer to Figure 6 for
guidance.
• The AIS transceiver should be mounted in a location where the
