6.1.2.1 If this insulation forms part of a semiconductor
component e.g. an optocoupler, there is no
distance through insulation requirement for the
insulation consisting of an insulating compound
completely filling the casing, so that CLEARANCES
and CREEPAGE DISTANCES do not exist, if the
component passes the electric strength test in
accordance with the compliance clause below and
in addition:
- passes the tests and inspection criteria of 2.10.8
with an electric strength test of 1.5 kV multiplied by
1.6 (the electric strength test of 2.10.7 shall be
performed using 1.5 kV): and
- is subject to ROUTINE TESTING for electric
strength during manufacturing, using a test voltage
of 1.5 kV.
N/A
6.1.2.1 It is permitted to bridge this insulation with a
capacitor complying with EN 132400:1994,
subclass Y2.
N/A
6.1.2.2 The exclusions are applicable for PERMANENTLY
CONNECTED EQUIPMENT and PLUGGABLE -
EQUIPMENT TYPE B only.
N/A
G.2 Due to the IT power distribution system used (see
annex V, figure V.7), the A.C. MAINS SUPPLY
voltage is considered to be equal to the line-to-line
voltage, and will remain at 230 V in case of a single
earth fault.
