Peter and Lasszlo
Somewhat conflicting points of view there.
A few thoughts in no particular order.
Lasszlo
If the buyer made an uninformed decision, and we don't know that for sure but it seems likely given that the EC had to ask the question, then one might wonder whether the buyer is the right person for that position.
It is not known if the seller was aware that the end user was in a different country with a different supply system. If he was, then yes, I agree that the differences should have been pointed out. But suggesting that the seller dishonest without better information seems just a wee bit harsh.

You are suggesting that the kit might just work. And it just might. Motors, maybe if the driven load....well see my previous post. And I seem to recall that the OP mentioned heaters. About 20% higher voltage would make me question that.
But I agree that it isn't for the electrician to be concerned about that. I don't know the status of the electrical contractor. If nothing else, he had the nounce to question the disparity between nameplate voltage and frequency and his supply. And you're right. A written confirmation from the manufacturer of what needs to be done to match equipment specification to supply would resolve the question of responsibility. It won't fix any technical issues that might arise.
