Supply voltage requirements
Observe the general requirements related to the supply power.
The supply voltage must kept within ±10% of the installation’s nominal voltage. Maximum
transient voltage variations on the main switchboard’s bus-bars must not exceed -15% to
+20% of the nominal voltage (except under fault conditions).
Electromagnetic compatibility installation guidelines
Kongsberg Mesotech Limited equipment and accessories are compliant with applicable
electromagnetic compatibility (EMC) regulations. This compliance ensures electromagnetic
interference (EMI) between the system components and other on-board equipment is
minimized to reduce the risk of performance degradation due to such interference. Correct
installation is required to maintain electromagnetic compatibility.
Employ the following recommendations to ensure the best EMC performance:
• Use only Kongsberg-specified cables and check that any ferrite suppression filters fitted
on the cables are installed as per the installation drawings. Suppression ferrites are
important for minimizing electromagnetic interference. If one has to be removed during
the installation, re-install the suppression filter in its original position on the cable before
using the system.
• Use a ferrite suppression filter installed on any third-party-supplied cable end attached to
M3 Sonar FLS equipment ports.
• Operate using standard length system interconnect cables unless cutting or cable
extensions are described in the installation manual.
• Install M3 Sonar FLS equipment and interconnect cables as follows:
– At least 1 meter (3.3 feet) from any equipment transmitting radio signals, antennas or
cables connecting the radio equipment to the antennas.
– At least 2 meters (6.6 feet) from SSB radios, antennas, and cables.
