Connection of four 4139 instruments in series

Hi Team, 

 

https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z000001DbUNSA0&l=en-IN

 

From the above link, we can connect in series, only with two instruments and force 150V ( isolation voltage of 4139 ). Is it true? & can i connect four instrument in series to force 240V? If not, In the link they mentioned "usually there’s a better alternative > 2 channels" can you please let me know which method I should follow to stack four instruments to force 240V?

 

Thank you.

You can get two 4137 and stack them together to get up to 400V
