Turntable + Preamp Ground?

My boyfriend just bought me an Edwards Audio Apprentice TT1 mk2 turntable. There is no ground wire coming from this turntable. What do I connect to the ground on the preamp? I don’t want any humming or buzzing, what do I do? The preamp is in transit and will arrive tomorrow. Maybe it won’t be a problem ungrounded.

The Turntable Lab: Rolls VP 29.TTL preamp will then be connected to a Denon S900W receiever (not audiophile grade but it’s what I have for now and I’m happy with it).

Thanks!
