ION 9k in series with existing meter

 

Hi Team,

 

Looking to install ION9000 IN SERIES with an existing Power Meter for a client. (existing meter may be retired later once there is confidence the ION9k is working OK)

 

Existing Meter setup has CT links and secondary earthing in-place as per below.

We were hoping we could extend the circuit to include the new meter as follows;

We have checked the burden on CT’s can handle the additional meter OK.

 

 

We want to be sure of how to configure CT wiring into ION9k as the install manual only makes specific reference to direct (exclusive use) wired CT’s.

My assumption is than we may need to link the -ve terminals of I4 & I5 to Q2-CC but I am not 100% sure.

 

Thanks

 

Grant

Thanks @Charles_Murison ,

 

assuming it was an SE engineer?

 

out of curiosity, was it the first or second version?

 

My latest revision based on your feedback below.

 

Is it better now?

Hello,

 

Yes an SE Engineer was the one to look. The revised diagram does match his suggestions.

Or thinking about it, would the revision below be more suitable?

Hello,

 

Showed this to an Engineer and most of this looks good. One recommendation is not connect Vn to Ve. Have Ve connected to earth. See direct connect WYE in installl guide.
