Notes:

1. Series module used in parallel connection for indication circuit connection.

2. LED indicator and associated circuitry are not included in the module.

3. Black wire is AC line voltage (hot); white wire is AC neutral voltage.

4. Black wire voltage is cut off when SPD needs replacement.

5. R is current limiting resistor; it resistance/wattage is determined by AC line voltage and

desired current driving LED. Example: AC line voltage 240V, LED: 1.6mA, resistor:

150Kohm/0.5W.
