Interesting you say that. Schneider might want to tell whoever it is that manufacturers the modules then. Because the manufacturer left a little sticker for the customer that talks specifically about the opening of power modules for servicing and states how long I should wait. I feel pretty silly I didn't notice this earlier!
So. the answer to this one is:
APC says to wait 5 minutes after removing a Power Module, before opening that module.
I'll also note, for the benefit of fellow Symmetra owners, I have successfully used an air compressor to dust all Power Modules (one by one while they were outside the Frame) It could take several minutes to remove all dust.
There may be areas on the circuit board where it looks like some sort of oil has spilled out, but it might not be oil, rather just dust that has really settled down. It may be removable with the electronics cleaner "I.D. Red" by Zep. Apply Red with one hand, and immediately after, while its still "wet", hit it with high pressure air from the compressor to remove the detritus that Red has loosened. Wear eye protection.
I did have to change the positioning of the power module during cleaning, from laying normally, to laying on each side, several times because there are places the heavier chunks of dust will settle on the sides that don't blow out when it's just sitting normally. It of course needs to be held when it's on edge so it doesn't fall over.
Don't forget to dust on both sides of the black plastic insulator sheets. Wash the lid with a wet rag separately from the module and its electronics.
Allow sufficient time for Red (and any moisture in the air hose) to evaporate before reinstalling the module, and I haven't had any problems from the cleaning process as described. Hope this helps someone out there.
