Thoroughly grounded soldering, measurement and test tools must be used. If these tools are
supplied with power from the 230 VAC mains, this supply must be protected by a fault current plug,
stock No. 593-8099.
Boards and units that contain ESD-endangered semiconductors are marked with the symbol shown
above.
All assisting persons who might come into contact with the endangered boards must also use the ESD
equipment.
DANGER
It is not permissible to connect the ship’s mains to the
system before setting-to-work by a qualified technician.
The mains must be switched off (e.g. by means of a
common isolating switch or a circuit breaker) in the ship’s
supply or the mains cable must be disconnected until
setting-to-work takes place.
If a synchro is connected to the Analog Interface or Inter-
face Expander, dangerous voltages might be present, even
although all supplies to the system are switched off.
Capacitors and tubes can store dangerous voltages for
several hours, even when they have been disconnected
from the supply voltage.
WARNING
Pay attention to the regulations for the prevention of accidents.
DANGER
Even when the system is switched off, there might be a
dangerous voltage present on exposed contacts. Therefore,
before a unit is opened, it must be ensured that the elec-
trical supply to all units is, and remains, disconnected from
the ship’s mains.
