Hi Jazz
Thanks for the reassurance. I'll give it a crack with a normal plug and some heavy wire. I'm a bit nervous about the 22 amp rating on the inverter case. I'd be grateful if any forumites that have used this vfd Hitachi wj200-022sf with a normal plug on it can chirp in with their opinions. I'm going to be using the spindle for wood routing and I know from experience that sharp cutters and and a powerful motor and not to deep cuts leads to a good finish and less stress on the machine and my nerves. I'd like to thank everyone here for their help as this is my first interaction with this forum, and look forward to further posts and replies.
Thank you all.

Cheers

Andrew
