Cleaning a frequency drive 1

[Thedroid]

What would be the best way to clean out a frequency drive that is exposed to a dusty environment. We have three ABB ACS 600's that are mounted to dollies that we use to run bucket elevators slowly so that the repairmen can inspect them. These elevators are located in a cement mill building, and the drives get pretty dusty in the process. I would like to clean them out every so often, but I had heard that a few had been ruined by static from blowing them out. We have an old 3M electronics vacuum, that claims to have a conductive hose and tip. I used this to clean one today and hopefully didn't ruin it. It was full of dust!! Is there a better way or recommended method for cleaning these drives. The manual doesn't give specifics, but it does say that it's alright to blow out the drive.

"I'm new to this company, been there 3 months. . . . I was told that the budget was real tight . . . housing market is a disaster. . . cement is not in high demand and management is in a panic. . . no expenses unless it's absolutely necessary . . . . I had trouble getting a pack of stickybacks and ty wraps."

Did your predecessor see the handwriting on the wall and jump ship ?

There are some drives on the market beeing designed for such enviroments. Buy such a unit when you have to replace the existing ones.

Yup, there are some units where the chassis is designed to meet NEMA12 environments. You can terminate some large cab-tire type cables for the temporary hook-up into it and it would stay sealed. The only thing that would need cleaning is the heatsink out the back which can be blown with air no problem. That would be a much better solution in this application.
