into a

NOTE: All 4PM slots need not be filled in order for the LE14XXA-Series unit to be operational. When leaving 4PM slots empty, always use a face plate ( 4PM-FP) to cover the slot opening in the front panel. This will maintain proper cooling air flow safety, and operation as required by FCC, CE, and other regulations.
