A small open-frame line powered power supply (Cincom CFM05S033) doesn't
have a ground connection. It will power a tiny device which only has
+3.3V/0V DC connections. This will be used in a 6x6x4 plastic enclosure so
there is no chassis ground. An electrician will be wiring it in.

Is this inherently unsafe? Do I need to find another supply with a ground?


Perhaps someone can suggest how to safely wire and enclose a small 3.3V
device with 120VAC power supply for use outdoors.
TIA
