DIN RAIL

*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.

MODEL: MD7PL

■ COM TERMINAL

• To protect more than three (3) signals with shared common line, it must be connected to the COM terminals of all MD7PL modules.

• Cross-wiring must be placed at the surge side of the MD7PL (terminal 6).

• Direct connection of the shared common line must be to the COM terminal of the MD7PL located closest to the grounding point.

• All MD7PL must be installed closely side by side on one DIN rail, so that the cross-wire be the shortest possible.
