Hi,
We misplaced our user manual for a CDI surge generator M/N CDI 1000i.
Does anyone know where we can get a copy of the manual as well as the
schematics?
Thanks in advance for any help.

Dear experts,
Does anyone know if anti- islanding relay in power inverter also needs to
disconnect a neutral conductor of 3W system? I have looked in UL 1741 and
couldn't find any requirement.
Thank you for your support.
With best regards,
Bostjan

Switching off neutral is not required, only the three phases. The pass
criteria is that you must cease exporting power by means of a disconnection in
the allotted time.
Thanks, - doug

Hello Bostjan,
You might want to check utility accessible equipment because utility wants
to integrate its use into their standard practices and procedures.
Thank you.
Best regards,

Certainly am NOT an expert on this stuff, or anything else for that matter, but
tend to agree with Mr. Powell.
In general, think that the much of the anti-islanding hoopla is non-issue
(except for first-responders), but some POCOs seem to believe otherwise. Have
seen stuff similar to this in
For years I assumed the anti-islanding requirement was to ensure distributed
generation (DG) goes offline when the main utility generating station also went
offline or out of spec, as a safety feature to allow line workers to safely do
their jobs.
After thinking it over, I had to ask
And IEEE1547 doesn't required a disconnection for unintentional islanding,
merely that the DG ceases to energize the local electrical power system.
(stop a negative power flow from the DG)
Some utilities in the USA and in Canada are suggesting that 500ms is a
better response time, to
