The 3300 System Rack permits convenient field expansion as specific plant requirements for monitored parameters grow.
Expansion is accomplished with the addition of rack sections.
With positions 1 and 2 reserved for the Power Supply and System Monitor respectively, up to 12 monitor positions remain. It is important that the bezel style of the expansion kit match that of the rack you wish to expand. Racks having a serial number beginning with RD or earlier will require the 01 option. Racks having a serial number starting with RF or later will require the 02 option. The serial number is located at the rear of the rack on the inside of the side panel, behind the Power Supply.
