## Questions & Answers

**Q: will we have a guide for installation since the information provided here seems complicated for a person like me?**
A: Charlotin,
The devices are supplied with user manuals. Also it can be sent via email. 
The installation is very simple, but must be done by a qualified professional to avoid personal injuries and any equipment damage.

**Q: Does this switch work with low voltage applications?**
A: I think not

**Q: I see that one of the specs says, "Provides external voltage adjustment feature". Can this product be used on low voltage applications (24V)changeover**
A: Unfortunately not. Because anyway the device must be powered by 120VAC voltage.

**Q: so the two powers must be at a minimum of AC 110 Volts ?**
A: This switch can work with power sources having 2-3 phases 120/240VAC where 120VAC (phase-neutral) and 240VAC (phase-phase).
