ARS Analog Series User and Service Manual P/N 821518 Rev-B Section 2: Operation Installation Mounting The ARS unit should be mounted in a rack or console where convenient for the expected level of operation. If only occasional operation is expected, the unit might be located higher or lower in the rack than would be advisable if it is expected to be used frequently. The unit's chassis is only six inches deep, so it may be more convenient to connect the cables from in front of the rack.
