I have an application where I need to wire two contactor in series (redundant MCRs). They are in line with each other. The wiring connection is a tab with a 1/4-20 bolt/nut.
My assembler would like to use a bolt-on alum plate the same size and thickness of the contactor's alum connection in...
Can I power up vfd without a load attached?
I need to verify paramters/set drive parameters to a panel I recieved but to not have the motors to attach as a load.

Yes benta, I am using a 3 phase 400V system. Control voltage is 230v by using a phase-neutral connecton.
What I need to know is this prohibited by codes/standards in European community (and UK specifically).
Control voltage will most likely be 230v whether I use a transformer or not. That is...
Looking at IEC 60204 9.1.1 states that where control circuits are supplied from an ac source control transformers shall be used.
Typically on a 380-415V+N supply I will pull my 220-240Vac single phase by using a one of the phases + N.
Looks like I cannot do this.
Can anyone with experience...
Most turbo applications seem to use a "stock" exhaust manifold. I believe the reasoning is to keep the turbo as close to the head as possible to aid in the spooling of the turbo.
I have an application where a "shorty" header is available...
