Hi,
Has anyone come across this problem.
While testing a network switch to EN 55022/24 and FCC Subpart B, the customer
insisted that a scrolling H must appear on a visual display used as a
peripheral of the network switch.
Test setup included a number of PCs, mouse, keyboard, and visual display.
Hi David,
We recently encountered this, testing a server in Taiwan for BSMI approvals.
We argued that the display is auxiliary equipment, only used to install and
debug, and the port would be not populated in final use. They insist not only
on scrolling Hs, but testing all screen resolutions
Both these are fairly standard disclaimers: they are not required by the
standard, but they allow the NRTL to establish that risk of access to energized
to parts in the end application is minimized. They are words I used often in my
technical, internal, reviews when establishing that
Brian, thanks for your input. Can the potential hazard be addresses without
English Text which may be misunderstood by those unfamiliar with the language?
Wouldn't Symbols Only be better?
John, good point. I hate battling issues with AHJs. We always put at least one
such warning label on our

CISPR 22 defines EUT as representative ITE or functionally interactive
group of ITE
KN22 and KN24 are based on CISPR22 and 24 not the EN standards, however if the
vdu is for maintenance only it would seem a little unreasonable to test with
it, unless you supply the vdu as well

Greetings.
We make laboratory equipment designed to the requirements of the IEC/EN/UL/CSA
61010-1 Ed. 3 standard.
Most electrical equipment has at least one warning somewhere visible on the
outside of the equipment that states something like, Disconnect Power Before
Servicing.
Where does this
Our NRTL asks for the warning No User Serviceable Parts Inside when that is
the case but that is relative to products complying with UL/EN 60950-1 and EN
60204-1. Of course that needs to be translated into all appropriate languages
too.
