4. KOM300 Grounding
The device grounding: please ground the Power grounding terminal (PG) and the Casing grounding terminal,
showing as Figure 7.
Grounding wires: The section should not be less than 2.5mm2 , grounding resistance <5, copper core.
Figure 4: Device grounding
Grounding method:
1. Casing grounding steps are as follows, as Figure 5-a:
a. Connect one terminal of grounding wire with the cold-pressing terminal
b. Use a grounding screw to fix the cold-pressing terminal to the casing grounding hole
c. Ground the other terminal of grounding wire
2. Power grounding steps are as follows, as Figure 5-b:
a. Strip 5mm-long sheath from grounding wires and twist the bare copper wires together into a bundle;
b. Use a 2.5mm one-slot screwdriver to unscrew the “grounding wires locking screw”, insert the grounding
wires into the hole at the terminal tail, and screw down the “grounding wires locking screw”.
c. Ground the other terminal of grounding wires

5. Hardware installation
For most industrial applications, 35mm standard DIN-Rail installation is very convenient. The DIN-Rail
connector has been fixed in the rear panel of KOM300. Figure 6 shows the dimension of DIN-rail installation.
Figure 6 Dimension diagram of DIN-rail installation
1. Before installation, make sure that the DIN-Rail is fixed well;
2. Insert the bottom of KOM300 into the DIN-Rail slot, and turn the equipment as figure 7-a
3. As Figure 7-b, put the DIN-Rail into slot, and make sure the device is completely fixed on the DIN-Rail.
