2. If you removed the terminal block from the station connector, mount the
block inside the enclosure.
3. Attach the ground wire from the station connector to earth ground. The lug
on the end of the ground wire accepts a number 10 screw.
Important: In the next step, do not pinch any wires between the cover plate and
the station connector enclosure. Also do not damage the gasket on the cover
plate, since this can nullify the NEMA type 13 rating of the station connector.
4. Attach the cover plate to the station connector.
