ACS880 Cooling Fans
We have our 230v coming off our transformer, going to our breaker and coming out of the breaker. Due to the tightness of area of the fan connection and company policy we cannot get into the area of the plug in to the fan while its live.
I really cannot see 4 fans not working from factory though.
Also we do not have any prints, the prints that we have are for our ACS800's.
Any help would be appriciated.
lastly we briefly tried to trace cables but in order to do so with this one we have to strip half the cabinet out.
In order for us to better understand what size it is, you can put the full code of your ACS880 drives.
Next, did you correctly follow all the assembly / connection instructions for these inverters? Generally the HW manual is very rich in information about it.
Last but not least, have you asked to your ABB local dealer about this issue?
