4.2 Mounting Steps
zKOM300M DIN-Rail Mounting
The specific steps are as follows:
Step 1: Select the mounting position for KOM300M and ensure that there is
adequate space.
Step 2: Insert the top of the DIN-Rail into the slot of the DIN-Rail connecting
seat in the rear panel of KOM300M as seen in Figure 5; move the device in
the direction of arrow 2 to put the whole Din-Rail into the seat; verify the
KOM300M is firmly mounted on the DIN-Rail, as shown in Figure 5.
Figure 5 DIN-Rail Mounting
zRemove KOM300M from DIN-Rail
The specific steps are as follows:
Step 1: Insert the screwdriver into the hole at the bottom of spring locking
plate; press the plate down to loosen the connection of DIN-Rail and switch,
as shown in arrow 1
Step 2: Pull the KOM300M up in the direction of arrow 2; meanwhile remove
the device from the DIN-Rail along the direction of arrow 3.

zKOM300M Panel Mounting
The specific steps are as follows:
Step 1: Select the mounting position for KOM300M on the wall or in cabinet;
ensure that there is adequate space for the switch.
Step 2: Drill 4 holes on the selected position according to the panel mounting
dimension drawings; use a cross-screwdriver to screw 4 cross-slot screws
(M3×10) into holes. Don’t tighten the screws completely; leave about 5mm of
space between.
Step 3: Aim 4 mounting holes on KOM300M mounting plate at 4 fixed screws;
pass the screws through 4 holes with the diameter of 6.5mm (Ф6.5); then slide
down KOM300M as seen in arrow 2; finally screw 4 screws tightly. Now the
KOM300M should be firmly fixed to the wall or cabinet.

5.2 100Base-FX Ethernet Port
100Base-FX Ethernet port is equipped with FC/ST/SC connector, and each port
consists of TX (transmit) port and RX (receive) port, as seen on the left in Figure
12.
100Base-FX port wiring is shown on the right in Figure 12 (Take SC port as
example; ST/FC wiring method is the same with SC). Connect the TX (transmit)
port of device A to the RX (receive) port of device B, and the RX (receive) port of
device A to the TX (transmit) port of device in order to transmit data between
device A and device B.

Note: A laser is used to transmit signals in fiber cables. The laser meets the requirements of
level 1 laser products. Routine operation is not harmful to your eyes, but do not look directly at
the fiber port or fiber connector when the switch is powered on.
5.3 Power
According to the power input requirements, use a 5.08mm-spacing terminal block
to connect power cable.
Note: The cross section area of power cable is required to be greater than 0.75mm2and less
than 2.5mm2. The grounding resistance requirement: <5Ω.

Step 1: Take the power terminal block off KOM300M
Step 2: Insert the power cable into the terminal block and fix the power cable
Step 3: Put the terminal block back to KOM300M with the connected cable
5.4 Grounding
zChassis grounding and power terminal grounding
Figure 14 Chassis Grounding and Power Terminal Grounding
There is a grounding screw on the top panel of the KOM300M, which is for
chassis grounding. One end of the chassis grounding cable is connected with
the grounding screw and the other end of the cable is reliably grounded. (The
cross section area of chassis grounding cable should be more than 2.5mm2.
The grounding resistance requirement: <5Ω)
The grounding part in the 5.08mm power terminal block is called surge
grounding.
It is required to connect the chassis grounding part with the surge grounding
part by an 18#AWG yellow-green line as seen below
z18#AWG yellow-green line (Unit: mm)

Note: If KOM300M needs to perform a dielectric voltage withstand test, in order to avoid test
failure, please disconnect the 18#AWG yellow-green line to disable surge protection circuit,
which connects to surge grounding.
