Installation Overview

The device's appearance is as in the figure below.
1. If you have purchased the wall mount kit,
proceed to place the screws on the back of the
device as shown in (Fig. 1)
2. Although internal grounding has been done
inside, in order to ensure overall maximum
performance and protect your device it is still
strongly advised to ground the device properly;
hazardous ESD can come into contact with it and
damage your equipment. On the power terminal block, there is a terminal for
Frame Ground, you can choose whether to connect it to the grounding or you may
opt to connect to the grounding screw next to the terminal block (the one chosen
should be connected at all times) (Fig. 2~4).

3. You can then choose whether to plug in the I/O ports at this point or do it later
depending on the actual location of the device or level of comfort for performing
7
such operation. Remember to plug in the protective caps for the unused SFP
and PoE ports.
4. Once the plate has been firmly put in place,
proceed to mount the whole device as shown
in (Fig. 5).
Proceed to (Fig. 6) if you want to remove the
device from DIN-Rail.
5. Next we can then proceed to connect the
1 device to the LAN (switch or PC, depending on
the case), take care on using the RJ-45

Attention
1. It is recommend to use at least 20 AWG cable and the cable needs to be resistant
to at least 85°C on the power connector.
2. Torque applied to the Terminal block's screw should be 4.5 in. lb (0.51 Nm)
3. The device needs to be installed inside a Type 1 housing.
