That is quite wrong. I see no reason not to store fiberglass ladders too. With both wood and fiberglass ladders there will be occasional metal parts. Probably more metal in a wood ladder than in a fiberglass ladder.Everybody knows your supposed to only store wood ladders in a drive cabinet! LOL!
They can’t wait for a new one, my team is going to rebuild it in the field by replacing just the inverter portion with a new one. We will not reinstall the ladder though.I'm guessing list price for a replacement is $50,000-$100,000 depending on how it's configured, what's the lead time on a 500HP 18-pulse drive? With downtime and installation that is one expensive ladder!
