*1. Without the MD7G, cross-wire between the DIN rail and the metal housing of the protected device to equalize the earth potential.

*2. Oxide film on the surface of an aluminium rail may lower the electric conductivity between this module and the ground. Use a steel or copper rail.

*3. Be sure to ground the DIN rail. Recommended grounding resistance ≤100Ω.
