FAQs
When I use a meter to measure the voltage at a loose terminal screw head, the result is lower voltage readings. Why?
With the GEMC-NAC7L / GEMC-NAC7S Supervised NAC Extender, and all GEMC terminal strips:
Be aware that terminal voltage originates from the bottom contact point on the terminal strips (not the terminal screw).
Therefore, ensure all terminal connections are tight and secure, or insufficient power to your wired appliances may result.
