Why doesn't the indicator light work on the SDSA1175 when wired to a 120Vac, 2-wire circuit?

Issue:
Why doesn't the indicator light work on the SDSA1175  when wired to a 120Vac, 2-wire circuit?

Product Line:
Surge protective device

Environment:
SDSA1175

Cause:
Circuit requirements not met

Resolution:
The indicating light requires 208Vac-240Vac, phase to phase, for operation. Therefore, the LED will not light when the unit is
applied to a 120Vac, 2-wire circuit. The device will function properly as a surge arrestor by connecting both black
leads to the one ``hot`` conductor and the white lead to the neutral. However, this would negate the benefit of the LED,
as well as provide a possibly functional device with a false indication that it is not functional.

For this reason, we now recommend a SDSA1175T for use on a 120Vac, 2-wire circuit.
