5.1.7.1 Touch current measurement results exceeding 3,5 

mA r.m.s are permitted only for the following 

equipment: 

- Stationary pluggable equipment Type A that: (1) 

is intended to be used in a Restricted Access 

Location where equipotential bonding has been 

applied, for example, in a telecommunication 

centre; and (2) has provision for a permanently 

connected protective earthing conductor; and (3) is 

provided with instructions for the installation of that 

conductor by a service person; 

- Stationary pluggable equipment Type B 

- Stationary permanently connected equipment 

6.1.2.1 Add the following text between the first and second 

paragraph of the compliance clause: 

If this insulation is solid, including insulation 

forming 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 0,4 mm, which shall pass the electric 

strength test below. 

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 2.10.11 

with an electric strength test of 1,5 kV multiplied by 

1,6 (the electric strength test of 2.10.10 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. 

It is permitted to bridge this insulation with a 

capacitor complying with EN 132400:1994, 

subclass Y2. 

A capacitor classified Y3 according to EN 

132400:1994, may bridge this insulation under the 

following conditions: 

- the insulation requirements are satisfied by 

having a capacitor classified Y3 as defined by EN 

132400, which in addition to the Y3 testing, is 

tested with an impulse test of 2,5 kV defined in EN 

60950-1:2006, 6.2.2.1; 

- the additional testing shall be performed on all the

test specimens as described in EN 132400; 

- the impulse test of 2,5 kV is to be performed 

before the endurance test in EN 132400, in the 

sequence of tests as described in EN 132400. 

6.1.2.2 The exclusions are applicable for permanently 

connected equipment and pluggable equipment 

type B and equipment intended to be used in a 

restricted access location where equipotential 

bonding has been applied, e.g. in a 

telecommunication centre, and which has provision 

for a permanently connected protective earthing 

conductor and is provided with instructions for the 

installation of that conductor by a service person.

1.7.2.1 In Norway, the screen of the cable distribution 

system is normally not earthed at the entrance of 

the building and there is normally no equipotential 

bonding system within the building. Therefore the 

protective earthing of the building installation need 

to be isolated from the screen of a cable 

distribution system. It is however accepted to 

provide the insulation external to the equipment by 

an adapter or an interconnection cable with 

galvanic isolator, which may be provided by e.g. a 

retailer.

similar information in Norwegian and Swedish

"Equipment connected to the protective earthing of 

the building installation through the mains

Connection to a cable distribution system has 

therefore to be provided through a device providing 

electrical isolation below a certain frequency range 

(galvanic isolator, see EN 60728-11)." 

NOTE: In Norway, due to regulation for installations 

of cable distribution systems, and in Sweden, a
