If input power is applied with the DC output BUS shorted, the active inrush circuitry will usually prevent Fuse 1 from blowing. Remove power, clear shorts, wait a few minutes and reapply input power. 2. If unit is strapped for 115V operation and 230V is applied, the internal overvoltage crowbar will clear Fuse 1. Replace fuse, strap correctly and reapply power. 3. To control EMI/RFI most effectively, the return path to earth ground from either the front end or modules should be made via a good RF ground. User must assure proper grounding for safe operation. Thermal Considerations Free Convection Derating • 250W: Derate output power linearly at 7.2W/˚C over 50˚C. • 500W: Derate output power linearly at 14.3W/˚C over 50˚C. • 750W: Derate output power linearly at 18.8W/˚C over 45˚C. Forced Convection: The curves below represent worst case data for chassis mounted (enclosed) front ends, i.e., low line, full load. System conditions such as higher line voltage, lighter load or PC mount versions of the front ends will increase reliability if the data here is used as the nominal design criteria. The sigmoid shape of the curves at low air flows is due to the chassis mount cover restricting the airflow to the inboard components until an airflow of approximately 200 LFM is achieved. Thereafter, the velocity of air rushing over the cover causes air to be pulled in through the side perforations, causing a rapid improvement of cooling of internal components. Max. Amb.
