a line powered bed heater via an SSR

So how would this configuration be done? can you make a sketch? or simply a brief summary of the cable connections?

If you had a line powered bed heater than your drawing is correct as shown.
The power supply feeds the Duet, the L (line voltage live) is connected to the SSR, the N (line neutral) is connected to one of the bed heater lines and the second bed heater is connected to the SSR output. Please use a thermal fuse ( attached to the bed and heater) between the SSR and the bed heater and make sure that the bed itself (and frame of printer) is grounded to line earth.
