3.4.5 Grounding
The ACU is internally grounded by connecting the appliance inlet earthing ground
to the power supply ground terminal.
The chassis unit is also internally bonded by connecting the appliance inlet
earthing ground directly to the chassis (#6 AWG screw with internal sems
washer).

3.5.1 Location
RFU placement is determined by first choosing an approximate location for each
RFU using basic coverage requirements, then identifying the mounting
configuration for each RFU (ceiling or wall). The number of RFUs is determined
by dividing an area’s square footage by the minimum RFU coverage area,
(32,000’). Typically, a floor plan of each story in the building is used as an aid to
identify RFU placement.
