To bring cables into the CPEC200 enclosure, remove the cap from

the cable feedthrough by loosening the thumbscrew and twisting

the cap while pulling it off.

To connect a wire to the DIN rail terminal blocks of the CPEC200

enclosure, insert a small screwdriver into the square hole to open

the spring-loaded contacts. Insert the wire into the corresponding

round hole and then remove the screwdriver. Gently tug the wire

to confirm it is secure.

Ensure the CPEC200 enclosure is not powered, and wire the power cable

(CABLEPCBL-L) from the EC100 electronics to the CPEC200 enclosure as

shown in FIGURE 5-8, FIGURE 5-9, and FIGURE 5-10.

Secure the SDM and power cables in the EC100 with a cable tie.
