Figure 2.3 – Surge Protected Terminal Connections (Top)

Figure 2.3 above shows the PROTECTED side of the Click 200. e UNPROTECTED

side of the Click 200 contains the same screw terminal connections, but are reversed from

left to right.

Note

See Appendix B for a description of how to wire the Click 200 using the old SmartSen-

sor cable as well as for a cable connector pin out diagram.

Wiring to Earth Ground

ALL Click 200 devices should be mounted on a DIN rail that is connected to earth ground

either through an earth-grounded chassis or a 16 AWG or larger grounding wire attached

to a 7-ft. (2.1-m) grounding rod. Follow the steps below to correctly wire to earth ground:

1 Connect the grounding wire from either the DIN rail or a GND screw terminal on

the UNPROTECTED side of the Click 200 to the lug bolt on the inside of the pole-

mount box.

2 Connect another grounding wire from the exterior lug bolt to earth ground (see Figure

2.4).
