1. The mat must be positioned at the workplace.
2. The potential equalization cable must be connected to the snap fastener and the clamp to a suitable
protective earth contact. The cable contains a 1 M
Ω resistor, which must not be removed.
3. The wristband must be put on. When the spiral cable is connected to the snap fastener, the discharge
line is established.
4. Thoroughly grounded soldering, measurement and test tools must be used. If these tools are supplied
with power from the 110 or 230 VAC mains, a fault current plug must protect this supply.
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 via an appropriate interface, 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 electrical supply to all units is, and remains, disconnected
from the ship’s mains.
