3.2.2. Rear Panel Controls
1. SCANNER BUS INPUT: Interconnect port for the control cable between the
SC6540 secondary and an automated Associated Research electrical safety
tester or SC6540 main Scanner.
2. SAFETY GROUND CONNECTOR: Must be connected to a known good
ground system to ensure operator safety.
3. HIGH VOLTAGE INPUT: Connector for input of high voltage from the host
instrument.
4. GROUND BOND OUTPUTS: Output channels for application of high current
for Ground Bond tests. These outputs are only available on SC6540
Scanners that are configured with a Ground Bond Module.
5. SCANNER BUS OUTPUT: Interconnect port for the control cable to another
SC6540 in a multiple SC6540 system.
6. ADDRESS SWITCHES: 8-pin DIP switch used to address the modules in a
SC6540 secondary or used to configure the address of a SC6540 main.
7. CURRENT INPUT JACK: Connector used to attach the high current input
lead or continuity current input lead from the host instrument.
8. RETURN INPUT: Connector for the return of the host instrument with the
SC6540. This connection provides the return current path for the high
voltage, Ground Bond current, and Continuity current.
9. HIGH VOLTAGE OUTPUTS: Eight individual output channels for high voltage
tests and Continuity tests. These outputs are only available on SC6540
Scanners that are configured with a High Voltage Module.
