The plug fits directly in to the mains supply socket, connecting with only the earth conductor. Live and Neutral pins have been moulded in insulating plastic, fitting into the supply socket but completely dormant.
At the front of the plug are connectors linked via 1M Ohm resistors to the earth pin, inside the plug. The connectors offer a link to ground for connecting cords from the EPA.
The 1M Ohm resistor to each connector offer protection in the event the workstation becomes live. That protection would limit the current to less than 0.3mA at 240 volts. Should the fault current continue the resistor will open circuit.
Insert the plug into the supply socket making sure it is fully home, then connect the various elements of the EPA…such as wrist strap cord, bench or floor matting connection cords. This ensures that the EPA is at the same earth potential. As generally the workstation has more than one plug socket it is possible to use more than one EBP if more connections are required.
Warning the plug must only be used for ESD control purposes.
The EBP is sealed and cannot be opened for repair. To test each connection use a multi-meter from the connector to the earth pin. The reading should be between 0.9 and 1.1M Ohms. As each connection point has its own 1M Ohm resistor, the resistance between two connectors should be approximately 2M Ohms. All EBP’s are tested and then packed in a pink anti-static bag
