*1.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.

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

*3.Cross-wire between the DIN rail and the metal housing of the protected device to equalize the earth potential.

Ground only the surge protector when the protected device has no ground terminal.

*4.Shield wiring method is an example. Proceed according to the system requirements.
