2 Installing the AIS Transpon der System Safely
Installation
WARNING: Do not connect the AIS transponder system to a mains (line) AC electrical
supply, as an electric shock or fire hazard could result.
CAUTION: Do not connect the Transponder to a DC supply exceeding 32 V or reverse the
supply polarity. Damage to the transceiver may result.
CAUTION: Do not bypass the built in fuse
CAUTION: The Transponder system is designed for operation in the temperature range
-15 °C to +55 °C. Do not install (or use) the transponder system in environments which exceed
this range.
CAUTION: The AIS Transponder is not water-resistant. Consequently, the Transponder must
be installed in a dry place and must be protected from direct contact with water.
WARNING: Do not install the Transponder system in a position where;
a) the controls of your vessel may be obstructed.
b) it may obstruct your normal movement around your vessel.
c) it may cause bodily injury.
d) it cannot be easily accessed in an emergency.
Use
WARNING: Certain parts of the Transponder chassis, notably the rear panel, can become
hot, particularly if the ambient temperature is high. Avoid touching these areas when the
Transponder is operating.
WARNING: Do not remove the cover of the Transponder before the power is switched off.
Do not touch the antenna connections when the Transponder is operating and do not touch the
antenna whip (mast) or connecting cable when the Transponder is in operation, for RF
exposure and electrical safety reasons. Refer to Radio Frequency Exposure Warning.
WARNING: Unauthorised opening of the Transponder system will invalidate the warranty.
Maintenance
CAUTION: Avoid using chemical solvents to clean the Transponder system as some
solvents can damage the case material.
NOTE: Apart from the fuse located beside the connectors, the Transponder system contains no
user serviceable parts. Contact your Service Agent for repair if replacing the fuse fails to make
the equipment servicable.
2 Issue 1 AIS Installation Manual
Radio Frequency Exposure Warning
To meet the current requirements for Radio Frequency Exposure it is necessary to install the
antenna mast correctly and operate the equipment according to the instructions.
The assumptions used in this assessment are: full transmit power is used, a good antenna is
used (assumed to be a unity gain (0 dB) wideband omni-directional type).
Where no suitable structure exists to achieve a 3 metre vertical separation then the antenna
base must be mounted at least 1 metre above the head of any person within range and all
persons must stay outside the 3-metre safety radius.
Failure to adhere to these limits could expose persons within the 3 metre radius to RF radiation
in excess of the MPE / SAR limits.
WARNING: The antenna mast must be mounted at a minimum distance (vertical separation)
of 3 metres from the head of any person standing on deck to meet international safety directives
on Maximum Permissible Exposure (MPE) / Specific Absorption Rate (SAR).
WARNING: Do not transmit when persons are closer than 3 metres to the antenna. If any
person (e.g. the operator) must be closer, then a grounded RF shield should be interposed
between that person and the antenna.
Rules of Operation
Licensing
IMPORTANT: In most countries the operation of the AIS Transponder is a part of the radio
regulations and therefore the ship must possess a current VHF radio telephone licence which
lists the AIS system, and the equipment must be registered (Call Sign and MMSI number).
Please contact the relevant authority in your country for more information.
Refer to the AIS Transponder Operation Manual for the full operating procedure.
Good Practice
The installer is expected to be familiar with IMO SN/Circ.227 Guidelines for the Installation of a
Shipborne Automatic Identification System, and to comply with these recommendations. The
document contains detailed information which supplements the instructions in this manual.

3 Introduction
It is recommended that the vessel should be surveyed prior to commencing any installation
work to determine the suitability of the existing on-board sensors. Section 8 of this Manual
contains a ‘Pre-Installation Inspection’ form to assist this process.
Installation of the AIS Transponder has been designed to be as easy as possible and requires
few tools. However as the AIS equipment forms a vital part of the ship’s navigational equipment
the installation must be performed with great care and with attention to detail.
The AIS is considered part of the ship’s radio station and is surveyed together with the radio
installation. Surveys on Convention ships should be carried out in accordance with the rules laid
down in IMO Res. A 746(18) Survey Guidelines under the harmonised system of survey and
certification and Protocol of 1988 relating to the International Convention for the Safety of Life at
Sea 1974
For the AIS installation, it is likely that the following drawings will be required for the survey:
• Antenna layout for the VHF and the GNSS antenna installation
• AIS Arrangement drawing
• Block diagram showing the interconnection to other units
To assist in the preparation of this information, a Pre-installation Inspection Record is included
in this manual at section 10. Completion of this Record will provide much of the required
information.
It is also necessary to complete an installation report, which shall be kept on board.
3.1 About this manual
This manual provides step-by-step guidance through the installation of the AIS Transponder
system. Please read the manual carefully and make sure to follow the instructions.
In this manual only the installation of the AIS stand-alone configuration will be described. If the
AIS unit is to be connected to other display devices, refer to the manual for that display.
However the setup must always be performed with the supplied Display uni t.. Other display
units will be additional to the IMO required installation.
The procedures required for installation can be summarised:
1. Obtain a copy of the AIS Pre-installation Inspection form; check that it is filled in with all the
data necessary for the installation. If the form has not been filled in, it is advisable to do it at
this stage, as this is a good way to make sure that all information is available for the
installation.
2. The available AIS Transponder system building blocks are listed in section 4.3. Before
starting the installation ensure that everything needed for the installation is to hand.
3. Locate the places to install the different units. The templates and the drilling instructions are
provided in this manual.
4. Connect the units and the sensors as shown in this manual.
5. DO NOT POWER UP THE SYSTEM AT THIS STAGE. It is most important to read the
Operation Manual, which contains the detailed commissioning information, before power is
applied.
6. Once the operating procedures are understood, the system may be powered up and the
permanent parameters may be set. A guide listing the steps in this procedure is provided as
Section 12 of this manual.
The Warranty Registration & Acceptance Record, Section 9 at the rear of this manual, must be
completed and signed when the system has been commissioned and accepted.

4 AIS Transponder System
4.1 System Configuration
The M-2 may be installed as stand-alone AIS equipment or integrated with Electronic Charting
Systems (ECS) or Integrated Bridge Systems (IBS).
Stand-Alone System The AIS transponder with Display unit is interfaced to the vessel's
primary navigation sensors. The Display is used as both the AIS display unit and AIS control
unit.
Electronic Chart System (ECS) with AIS In this arrangement the stand-alone AIS installation
and ECS display have been integrated. The Display is used mainly to input own ship's
information with the ECS having the ability to display AIS target information. This arrangement
greatly enhances the presentation of information by displaying AIS targets in an environment
normally used for navigation of the vessel.
Integrated Bridge System has the ability to display AIS target information directly on an
Automatic Radar Plotting Aid (ARPA ) or Electronic Chart Display and Information System
(ECDIS). By combining these technologies the navigator is provided with the optimum
navigational information, directly on the vessel’s primary navigation display. Where approved for
this purpose the ARPA or ECDIS equipment maybe used to directly control the function of the
AIS transponder.
4.2 Installation accessories
An optional AIS installation cable kit contains all the basic installation materials and cables that
are typically needed to ready a vessel for installation of the AIS equipment.
Other accessories incl ude a VHF antenna and a range of antenna bracket options, an AC/DC
power supply unit, a Gyro Interface Unit (Stepper/Synchro gyro input - RS422 output) and a
remote IMO Pilot Plug kit. (The Pilot Plug may be supplied with the system, depending on the
configuration ordered.)

5 Mechanical mounting options and guidelines
5.1 Location
The transponder unit is classed as protected equipment and thus should be located inside in a
dry environment. Normally the transponder is located in the Radio Room. The transponder
compass safe distance is 2.1 m.
The recommended location should provide:
A dry environment
Access to connections (eg antennas, power, sensors)
Minimal shock and vibration
An ambient temperature between -15 °C and +55 °C
A site clear of exhausts and vents
Sufficient space to allow maintenance
The transponder does not require external illumination during operation. Naturally, some form of
illumination should be provided while installing or maintaining the transponder.
The Display should be available to the mariner at the position from which the ship is normally
operated. The Display compass safe distance is 0.7 m. The Display does not require external
illumination during operation, as it has an internal backlight; the use of illuminated keys ensures
that all controls are visible.
The Pilot Plug should be installed on the bridge near the pilot’s operating position. It is
recommended that a suitable mains outlet (3-pin 120 V AC) should be available at this location.
Special siting considerations apply to antennas. These principles are outlined in section 5.4; for
detailed advice, see the IMO Guidelines.
5.2 AIS Transponder unit
The transponder mounting plate is attached by four M6 screws. Keyhole slots in the plate allow
two screws to be inserted in the mounting surface , then the plate to be mounted on the screws
and to be self-supporting while the remaining screws are inserted and all screws are tightened.
The transponder chassis is then attached to the plate using four screws, as shown overleaf. The
transponder may be mounted at any angle.
It is recommended to leave at least 300 mm free space around the terminals to allow for
connection cables.
