Back Panel Controls

1. EXTERNAL MD : Provides an access port for a custom measuring device. The port may be activated during Line Leakage testing from the instrument’s menu system. The operator must supply the appropriate measuring device as none is provided.
2. FUSE RECEPTACLE: To change the fuse unplug the power (mains) cord and turn the fuse cap counter clockwise.
3. CALIBRATION ENABLE KEY: To enter the calibration mode press this key while the instrument is being powered ON.
4. SIGNAL INPUT: 9 pin D subminiature male connector for remote control of TEST, RESET, AND INTERLOCK functions as well as remote memory tests selection.
5. SIGNAL OUTPUT: 9 pin D subminiature female connector for monitoring PASS, FAIL, and PROCESSING output relay signals.
6. DUT POWER INPUT: Provides the line and neutral connections for an input power source to be used during Functional Run and Line Leakage testing. This input requires connection to a U.S. style single phase unbalanced power supply.
7. DUT POWER OUTPUT: Provides the line and neutral connections from the 6330 to the DUT during Functional Run and Line Leakage testing. Provides the high voltage connections to the DUT during ACW, DCW and IR testing if the DUT OUTPUT and DUT-HV parameters are turned ON.
8. GND CONNECTION: This terminal is wired in parallel with the Current Output terminal during a Ground Bond test and may be used in place of the front panel connection. During a Line Leakage test this connection provides a connection to one side of the measuring device (MD).
9. CASE CONNECTION: This terminal is wired in parallel with the Return terminal during a Ground Bond test and may be used in place of the front panel connection. During a Line Leakage test this connection provides a connection to one side of the measuring device (MD). During ACW, DCW or IR testing this terminal provides the return connection.
10. CHASSIS GROUND (EARTH) TERMINAL: This safety terminal should be connected to a good earth ground before operation.
11. INPUT POWER RECEPTACLE: Standard IEC 320 connector for connection to a standard NEMA style line power (mains) cord.
12. VOLTAGE SELECT SWITCH: Line voltage selection is set by the position of the switch. In the left position, it is set for 115-volt operation, in the right position it is set for 230-volt operation.
13. TERMINAL FAN: To cool the instrument.
