Quick question about tdw20 install?

[sn47som]

I just received a brand new td-20 and the tdw20 expansion card. hasn't even been opened yet. Can I install the expansion card first even before I turn the module on for the first time, or should I atleast turn the module on 1 time to let it run factory settings for the first time, then install the card?

I think that is the safest thing to do.
