FreeLists / si-list / [SI-LIST] ESD on center pin of 6VDC jack input.

[Chandan M <Chandan.M@xxxxxxxxxxxx>]

Hi,
We are developing a handheld equipment, which can work on both battery and 
AC/DC adapter. 
AC/DC adapter is not mandatory to be connected while using the equipment. 
Also there is no connection between the equipment and the earth while 
operating on battery.

The DC jack is not accessible in normal use. where as it is accessible 
with IEC test finger.

What I am wondering is, should we do contact discharge on the center pin 
of the DC jack? And if we need not, I want to know the reason why we need 
not? 

I will be grateful if any can give some info on that.

Regards,
Chandan.
