"Earth Loop" Connections on UK power connector?

| Sorry for the repeat! I posted this back in February and am STILL
trying to figure out what to do with all these earth connections at the
equipment end. At our customer's request, we're installing a UK power
inlet that has three earth terminals: Protective Earth (green/yellow),
and
E1 and E2 (yellow). It describes the E1 and E2 terminals as "2
functional earths (E1, E2) for high integrity "earth loop"". This is
something new to me. Can someone describe how E1 and E2 are used? Do we
just connect all three to our ground lug in the cabinet?
THANKS!
Harold

Sorry I can't directly answer your question but you could try asking here
http://www.theiet.org/forums/forum/ you may have to register with the IET
(formerly the IEE and IIE). Someone there should be able to answer your
question.

| Have never seen an outlet with 3 earths.
Functional earth hmmm you must be using something that has a high earth
leakage. This would normally be connected to a 'clean' earth bar.
Any chance of a photo or a better discription of its usage

| As i thought IT equipment.
The 3rd earth is for supplementry bonding purposes
The Earth E1 is main earth and E2 is functional earth to go to a clean earth
bar in the IT room

So, inside the piece of equipment, do we just tie the three ground
leads (PE, E1, E2) to the chassis?
Thanks!
