· The use of multi-socket electric mains extender without additional protective
actions is prohibited. The fact is that the probable break of the circuit of the
protective ground of the multi-socket electric mains extender can lead to
summation of leakage current in all connected units on their metal parts to
dangerous values.
· To avoid electrical shock, the mains plug must only be inserted in an
appropriate mains socket outlet provided with a protective earth (ground)
contact.
· Before the digital EEG system setting, the electrician must check the quality
of standard tripolar sockets and the integrity of the protective ground circuit.
· In case the system components are connected to several tripolar sockets,
make sure they are grounded to one and the same protective ground circuit.
Otherwise, there is a danger of several tens of mA leveling current leakage
through the system connecting cables that leads to the equipment
breakdown.
The typical schematics of the equipment location when connecting to the desktop PC
and notebook PC are given below (Fig. 5, Fig. 6).
