three outputs. An overload on any output will cause the voltage to collapse and may cause the other output voltages to collapse. Normal operation will resume after removal of the overload. Some component cooling time may be required before normal operation resumes. Over Temperature Protection The IC698PSA100 power supply can operating at full capacity (100W) from 0 to 60ºC with only convection cooling. The IC698PSA350 power supply is capable of operating at full capacity (350W) from 0 to 60ºC with 70 CFM forced air cooling provided by a fan tray mounted below the system chassis. This power supply can operate at a limited capacity with only convection cooling. See the temperature derating curves on the next page. The RX7i power supplies have internal temperature sensing that shuts down the output channels when overheated. The overtemperature failure allows automatic recovery once the unit cools down. 4 RX7i Power Supplies GFK-2237F Temperature Derating Curves for IC698PSA350 without Forced Air Cooling Load (%) 100 80 60 40 20 0 10 20 25 30 40 50 60 70 Temperature (°C) 85Vac 120Vac 220Vac/240Vac/300Vac Load (%) 100 80 60 20 0 10 20 25 30 40 50 60 70 Temperature (°C) 100Vdc/125Vdc 150Vdc Airflow Sensor An airflow sensor is provided in the 120/240 VAC/125 VDC and 350 W power supplies to detect a fan failure or air blockage. If the power supply senses a cessation of air flow, it responds by latching off all outputs and turning on the overtemperature LED indicator. The power supply automatically recovers from this condition when the internal temperature has decreased to operating levels. You can enable or disable the airflow sensor via a jumper located on the outside of the Power Supply. The airflow sensor option is enabled (jumper on pins 1 and 2) as the default for each power supply. To disable the airflow sensor, place the jumper on pins 2 and 3. Front Panel Jumper installed on pins 1 & 2 of P3 (Airflow sensor enabled) Jumper on pins 2 & 3 disables airflow sensor.

Hazardous voltages may exist. Personal injury, damage to the module, or unpredictable operation of the device or process being controlled may result. This Power Supply is a plug-in module that is installed in the leftmost slot of any standard RX7i rack. For additional installation information, refer to PACSystems RX7i Installation Manual, GFK-2223. Power Source and Ground Connections The input terminals are located on the front faceplate of the power supply. The top two terminals (L1|+ and L2/N|-) are used for 120/240 VAC and 125 VDC inputs. Power input connections should be made with copper AWG #16 (1.3 mm2 ) wire rated for 75°C (167°F). Each terminal can accept two solid or stranded wires, but the wires into any given terminal should be the same type and size. The terminal can accept a single wire connection up to AWG #12. All wire lengths should be stripped to 0.25” (7mm). Longer stripping lengths will result in exposed power wires, which is a potential shock hazard. The GND (ground) terminal on the power supply should be connected to the GND terminal on the rack and to earth using copper AWG #12 (3.3 mm2 ) wire rated for 75°C (167°F) to ensure adequate grounding. Use of a ring terminal and star washer to ensure ground integrity is recommended. Terminal Board Connections for IC698PSA100/350 System Noise Protection The following steps must be taken to reduce the possibility of errors due to electrical noise. Make sure that the power supply mounting screws are properly secured. Properly ground the system as described in “Power Source and Ground Connections” above. Note: Each RX7i module has a noise reduction gasket on the right side of the faceplate that maintains contact with the adjacent module or the rack. (RX7i power supplies have the noise strip on both sides.) Installing modules that do not have this strip makes the rack system more susceptible to electrical noise.
