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 ≤100Ω

*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.

Without Fuse/Disconnect option, fuse circuit is shorted.

*4.

Specifications are subject to change without notice.
