General Safety Information for Service Personnel
DANGER
Life danger through electrical shock
Hazardous voltage is present at the transducer terminals located on the
fore and aft channel transmit/receive PCBs in the preamplifier D.
Danger of electrical shock or burn when the transducer terminals are
touched while power is applied to the preamplifier.
Never touch the transducer terminals and connect or disconnect the
transducer cable while power is applied to the preamplifier.
WARNING
Risk of electrical shock
When wiring up the system, accidental switching-on of the AC supply
power will energize the system.
Always make sure that the power supply for the NAVIKNOT system is
switched off and is safeguarded against accidental switching-on, when
wiring up the system.
CAUTION
Risk of damage
Components on the devices’ PCBs are sensitive to static discharge.
Electrostatic discharge may permanently damage components.
Take the necessary precautions to prevent electrostatic discharges.
Avoid touching any of the electronic circuitry.
CAUTION
Risk of damage
The NAVIKNOT 600 SD electronics unit contains electrostatic sensitive
components.
Electrostatic discharge may permanently damage components.
Take the necessary precautions when servicing the electronics unit to
prevent electrostatic discharge.
Avoid touching any of the electronic circuitry.
CAUTION
Risk of damage
Incorrect assignment or mismatch of the CDU IDs will lead to incorrect
CDU settings and may corrupt the system functionality.
Always make sure that the CDU IDs are uniquely assigned when install-
ing the NAVIKNOT system.
Note The default ID „0“ is reserved to automatically assign a single CDU as the
permanent Master CDU.
In case more than one CDU is installed, the ID „0“ is not allowed to be
assigned in any combination with other unique IDs of other CDUs.
CAUTION
Damage to the transducer function caused by cabling changes
Cutting or shortening of the transducer cable or connecting new cables
with existing old cabling will lead to damage or malfunction.The given
length of any specific transducer cable is a necessary element of its per-
formance. Cutting or shortening as connecting to old cabling will harm
the performance characteristics of the transducer cable and lead to mal-
function of the transducer.
Always use the transducer cables in the original length. Never cut or
shorten the transducer cables. Rewire excess cable length in a loop if
necessary. Never connect a new transducer cable to old cabling.
