According to this site: http://www.botzilla.com/photo/strobeVolts.html


your flash trigger voltage is 6.8V so it seems like it will be ok to put it on your Canon (but read on!)... on the other hand, on the "EOS safe?" column in their table they put "Your Call" - so I guess they are right, it's your call.


If you ask for my personal opinion - I wouldn't mount it at all to my camera. Not on the hot-shoe and even not with a PC cable (even though the 50D PC terminal can handle up to 250V according to the manual).
