Configuration Tool (Option) 8. Dimensions, Basic Specifications 9. Troubleshooting absolute humidity 1.25 g/m; rate of temperature change < 0.5 C/min. These parameters are dealt with in the following paragraphs. Under these conditions the unit or system starts and works without any prob- lem. Beyond these specifi cations, possible problems are described below. Ambient Temperature Units and systems by Studer are generally designed for an ambient tempera- ture range (i.e. temperature of the incoming air) of +5 C to +40 C. When rack mounting the units, the intended air fl ow and herewith adequate cooling must be provided. The following facts must be considered: The admissible ambient temperature range for operation of the semicon- ductor components is 0 C to +70 C (commercial temperature range for operation). The air fl ow through the installation must provide that the outgoing air is always cooler than 70 C. Average heat increase of the cooling air shall be about 20 K, allowing for an additional maximum 10 K increase at the hot components. In order to dissipate 1 kW with this admissible average heat increase, an air fl ow of 2.65 m/min is required. Example: A rack dissipating P = 800 W requires an air fl ow of 0.8 * 2.65 m/min which corresponds to 2.12 m/min. If the cooling function of the installation must be monitored (e.g. for fan failure or illumination with spot lamps), the outgoing air temperature must be measured directly above the modules at several places within the rack. The trigger temperature of the sensors should be 65 C to 70 C. Frost and Dew The unsealed system parts (connector areas and semiconductor pins) allow for a minute formation of ice or frost. However, formation of dew visible to the naked eye will already lead to malfunctions. In practice, reliable opera- tion can be expected in a temperature range above 15 C, if the following general rule is considered for putting the cold system into operation: If the air within the system is cooled down, the relative humidity rises. If it reaches 100%, condensation will arise, usually in the boundary layer between the air and a cooler surface, together with formation of ice or dew at sensi- tive areas of the system (contacts, IC pins, etc.). Once internal condensation occurs, trouble-free operation cannot be guaranteed, independent of tempera- ture. Before putting into operation, the system must be checked for internal for- mation of condensation or ice. Only with a minute formation of ice, direct Appendix IX evaporation (sublimation) may be expected; otherwise the system must be heated and dried while switched off. A system without visible internal formation of ice or condensation should be heated up with its own heat dissipation, as homogeneously (and subsequently as slow) as possible; the ambient temperature should then always be lower than the one of the outgoing air. If it is absolutely necessary to operate the cold system immediately within warm ambient air, this air must be dehydrated. In such a case, the absolute humidity must be so low that the relative humidity, related to the coldest system surface, always remains below 100%. Ensure that the enclosed air is as dry as possible when powering off (i.e. before switching off in winter, aerate the room with cold, dry air, and remove humid objects such as clothes from the room). These relationships are visible from the following climatogram. For a con- trolled procedure, thermometer and hygrometer as well as a thermometer within the system will be required. Example 1: An OB-van having an internal temperature of 20 C and a relative humidity of 40% is switched off in the evening. If the temperature falls below +5 C, the relative humidity will rise to 100% (7 g/m); dew or ice will be forming. Example 2: An OB-van is heated up in the morning with air of 20 C and a relative humidity of 40%. On all parts being cooler than +5 C, dew or ice will be forming. Appendix X Appendix 2: Mains Connector Strain Relief For anchoring connectors without a mechanical lock (e.g. IEC mains connec- tors), we recommend the following arrangement: Procedure: The cable clamp shipped with your unit is auto-adhesive. For mounting please follow the rules below: The surface to be adhered to must be clean, dry, and free from grease, oil, or other contaminants. Recommended application temperature range is +20 C to +40 C. Remove the plastic protective backing from the rear side of the clamp and apply it fi rmly to the surface at the desired position. Allow as much time as possible for curing. The bond continues to develop for as long as 24 hours. For improved stability, the clamp should be fi xed with a screw. For this purpose, a self-tapping screw and an M4 bolt and nut are included. Place the cable into the clamp as shown in the illustration above and fi rmly press down the internal top cover until the cable is fi xed.
