Grounding

*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 ≤100

*3. Cross-wire between the DIN rail or the terminal 7 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.

Specifications are subject to change without notice.
