Re: [PSES] Products requiring dielectric voltage withstand test on RJ45 and XLR sockets

Hi Chuck:

 

I don't know why your lab wants to do the primary-circuits-to-ground hi-pot
test to "unearthed socket terminals."  I assume your secondary circuits are
grounded, and, if so, the pins of sockets (RJ45 and XLR) are therefore
referenced to ground and are subject to the primary-to-ground voltage..
Same for USB terminals.  (If the RJ45 and XLR circuits are floating or if
your product is two-wire mains, then the respective circuits must be
grounded during the test.)

 

Of course you can do the accessibility test to the pins to show that they
are inaccessible.  However, I would assemble RJ45 and XLR mating connectors
with all pins connected together and attached to a wire whose far end is
grounded during the test.  This assures all the terminal pins are grounded
and meets the lab's requirement.  (Note that the product is non-operational
during the hi-pot test, so grounding all the pins does not damage the
product.)

 

I could not find justification for 3600 volts peak.  Can you justify this
test voltage in the standard?

 

Best regards,

Richard

I'm working with a new lab and new product using IEC 62368-1 3rd Ed.

they are asking the company to perform production line test dielectric
voltage withstand test of 3600 Vp or DC 1 to 4 seconds on Ethernet port
connector RJ45 and Pro Audio XLR connector sockets?

"Between primary to other accessible conductive part- L/N of plus pins to
accessible unearthed socket terminals"

 

Can I use the IEC 62368-1 3rd Ed. blunt probe of Figure V.3 to show that the
pins are not accessible and need not be tested?

 

Anyone else must production line Hipot Ethernet port connector RJ45 or Pro
Audio XLR connector sockets?

 

Thank you for the help.

 

 

Chuck

[Ralph McDiarmid]

If you test that connector with the blunt test probe (aka finger probe)
using the procedure described in the standard and it does not touch the
connector pins (and you have minimum clearance) then your certifier should
reconsider the dielectric test level.  Many standards still use basic and
reinforced insulation concepts along with working voltage to determine
dielectric type test and routine test levels.

Thank you for pointing to IEC 62911 standard.

Hello Chuck,

Typical issue with reading the standard. Standard IEC 62368-1 3rd Ed only 
defines routine tests on some components, where there is a reference to routine 
tests (e.g. transformer, optocoupler,... - search for reference to 5.4.9.2). 
Complete unit shall be tested in production based on requirements of IEC 62911 
standard.

Best regards,
Boštjan
