Can a SDSA1175 be used on a 120V, single phase, 2-wire application?

Issue:
SDSA1175 LED will not light illuminate when applied on a 120V, single phase, 2-wire application?

Product Line:
Surge Protector

Environment:
SDSA1175

Cause:
single phase application

Resolution:
The SDSA1175 is configured to be used on a 120/240V, 1 Ø, 3-wire system. Applying this device on a 120V 1 Ø, 2-wire application will not work properly because the indicating LED will not be functional. The SDSA1175 needs to have 240V between both black leads in order to function properly. For 2-wire applications the correct device that should be used is the SDSA1175T.

*Note
Two SDSA1175 units may be installed to provide suppression on 208Y/120V 3 Ø, 4-wire services. Systems must be solidly grounded. Do not use the SDSA1175 on ungrounded systems.
