1. Prior to installation, an 8-3/8 ± 1/8 in. [213 ± 3 mm]
diameter hole must be cut or preformed into the raised
floor panel or wood floor. If knockouts on sides of box
are to be used, proceed to steps 4 and 5. Pull cable and
conduit through opening prior to termination.
2. If necessary, use bushing(s) and wire tunnel to facilitate
wire and cable routing. Remove the temporary cover and
the (5) #8 hex screws securing the device mounting plate
and lift it out of the box, exposing the internal barriers.
Remove necessary knockouts and twistouts between
compartments to allow desired wiring layout. Replace the
internal barriers and reinstall the device mounting plate
back in its original orientation.
3. Attach flexible conduit and fittings to the steel box body.
Terminate wiring devices in compliance with the NEC
