EN60204§6.2.1.
b. All active metallic parts are insulated against inactive metallic parts which the
people could come in touch with, according to EN60204§6.2.2
c. External connecting elements, which the people could come in touch with have
the active parts entirely insulated, according to EN60204,§6.2.2
d. Galvanic separation of control circuit by transformer, according to
EN60204§6.3.3
e. Use of reduced voltage(PELV)OF 24 V for supply of control circuit, according
toEN20204§6.4
f. In order to avoid undesired acting owing to insulation damage, broaking or
detaching of connections of conductors in the control circuit, a branch o this circuit
is connected to the
protection circuit, according to EN60204§60204§8.4
All inactive metallic parts of machine are earthed according to EN60204-1§5.2,
§8.2 and EN60445 in order to protect people against dangers caused by fault of
insulation or accidental touching between active and inactive metallic parts.
Earth link between machine and ground clamp of the mains is made by means of
feeder cable and must be checked to be correctly executed.
it is forbidden to put the machine under voltage before connecting it to the ground
clamp of the mains and before verifying the earth circuit according to instructions
from $8.2.1From time to time it is necessary to check if continuity of earthings is
assured and all instructions from §8.2.1 are respected.
