6.1.2.1 S 

(NO, SE)

 Add the following text between the first and 

second paragraph: 

If this insulation is solid, including insulation forming a 
part of a component, it shall at least consist of either 

- two layers of thin sheet material, each of which shall 
pass the electric strength test below, or 

- one layer having a distance through insulation of at 
least 0.4mm, which shall pass the electric  strength test 
below. 

If this insulation forms a 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 1.5kV multiplied by 1.6 (the 
electric strength test of 2.10.7 shall be performed using 
1.5kV); and 

- is subjected to routine testing for electric strength 
during manufacturing, using a test voltage of 1.5kV. 

It is permitted to bridge this insulation with a capacitor 
complying with EN 132400:1994, subclass Y2

 

 

No TNV circuits. 

6.1.2.2 S  

(FI, NO, SE)

 The exclusions are applicable for 

Permanently Connected Equipment and 
Pluggable Equipment Type B only  

No TNV circuits. 

G.2 S 

(NO)

 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 230V in case of a 
single earth fault 

Considered. 

Annex H C 

Replace the last paragraph of this annex by: At 
any p oint 10cm from the surface of the operator 
access area, the dose rate shall not exceed 
1

µ

Sv/h (0.1 mR/h) (see note). Account is taken of 

the background level. 

The unit does not emit X-ray radiation. 

Annex H C 

Replace the note as follows: NOTE – These 
values appear in Directive 96/29/Euratom 

The unit does not emit X-ray radiation.
