2. Route the probe cable and your power/signal cable through

the cable glands. The power/signal cable should be 5 ... 10 mm in diameter.

The larger cable gland is meant for the probe cable - push the probe through it from the inside.

3. Connect the power/signal cable to the screw terminals. Refer

to the HMM100 User's Guide for wiring instructions.

4. Attach the probe cable and the power/signal cable to the right

side of the bracket using the screws and metal clips (included). See Figure 4 for the suggested placement.

Make sure that the shield of the power/signal cable makes good contact with the bracket. If your cable is unshielded, you can provide the earth connection by using a separate cable and the Abiko connector provided (visible in Figure 4).

6. Assemble the rubber plug around the probe cable, and push it

into the cable gland. See Figure 6.

5. Mount the bracket to the bottom of the housing using the two

large screws that are preinstalled in the bottom of the housing. The cables should face right toward the cable glands. See Figure 5.

NOTE When you place the cover on the housing,

match the two raised corners with the indentations on the cover. Otherwise the housing will not close tightly.

8. Mount the housing in the desired location. For mounting

dimensions, see Figure 7. The diameter of the screw holes for mounting the housing is 5.2 mm.

9. Verify the installation: power up the module and check the

output reading.
