3.Installation
Precautions:
⚫Power supply requirements: 24 V DC (12–48 V DC).
⚫Environment requirements: operating temperature –25°C to 75°C; storage temperature –
40°C to 85°C; relative humidity 5% to 95% (non-condensing). The temperature on the
device surface may be high. Install the device in a restricted area and assess the
surrounding environment.
⚫Avoid direct sunlight and keep away from thermal sources or areas with strong
electromagnetic interferences.
⚫Install the gateway product on an industrial DIN-rail.
⚫Check whether the required cables and connectors are installed.

3.1.Installing and Uninstalling the Device on a DIN-Rail
3.1.1.Installing with a DIN-Rail
Procedure:
Step 1: Select an installation place and reserve enough space for installation.
Step 2: Insert the upper part of the DIN rail seat onto the DIN rail. Grab the lower end of
the device and revolve it upward in the direction indicated by arrow 2 with gentle force, to
insert the DIN rail seat onto the DIN rail. Check that the device is installed reliably on the
DIN rail, as shown in Figure 3-1 on the right.
Figure 3-1-1 DIN rail installation schematic diagram
3.1.2.Uninstalling with a DIN-Rail
Procedure:
Step 1: Press the device downward in the direction indicated by arrow 1 in Figure 3-2 to
create a gap near the lower end of the device so that the device isolates from the DIN rail.
Step 2: Revolve the device in the direction indicated by arrow 2, and grab the lower end
of the device and move the device outward. Lift the device when its lower end isolates from
the DIN rail. Then, take off the device from the DIN rail.

3.2.Installing and Uninstalling the Device in Wall-mounted
Mode
3.2.1.Installing in Wall-mounted Mode
Procedure:
Step 1: Select an installation place and reserve enough space for installation.
Step 2: Install the wall mounting bracket on the back of the device by using a screwdriver,
as shown in Figure 3-3.
Figure 3-2-1-1 Wall mounted installation diagram
Step 3: Take out the screws (packaged with the wall mounting bracket), fasten the screws
in the installation positions by using the screwdriver, and pull down the device to make it
secure, as shown in Figure 3-4.
Figure 3-2-1-2 Wall mounted installation diagram
3.2.2.Uninstalling in Wall-mounted Mode
Procedure:
Hold the device with one hand and unfasten the screws that fix the upper end of the
device with the other hand, to remove the device from the installation place.

3.3.Installing a SIM Card
IG502 supports Dual SIM card.
Figure 3-3 Install SIM card

3.4.Installing an Antenna
Revolve the movable part of the metal SMAJ interface with gentle force until it cannot be
revolved, in which state the outer thread of the antenna connection cable is invisible. Do not
wring the antenna with force by grabbing the black plastic cover.
Figure 3-4 Installing an Antenna
Note
⚫IG502 supports dual antenna: ANT antenna and AUX antenna. The ANT antenna sends and
receives data. The AUX antenna only increases the antenna signal strength and cannot be
used independently for data transmission.
⚫Only the ANT antenna is used in normal cases. It is used with the AUX antenna only when
signal is poor and signal strength must be improved.

3.5.Installing the Power Supply
Procedure:
Step 1: Remove the terminal from the gateway.
Step 2: Unfasten the locking screw on the terminal.
Step 3: Connect the power cable to the terminal and fasten the locking screw.
Figure 3-5 Installing the Power Supply
3.6.Installing the Ground Protection
Procedure:
Step 1: Unfasten the ground screw cap.
Step 2: Put the ground loop of the cabinet ground cable onto the ground post.
Step 3: Fasten the ground screw cap.
Caution
Ground the gateway to improve its interference resistance. Connect the ground
cable to the ground post of the gateway based on the operation environment.

3.7.Connecting the Network Cable
Connect the gateway to a PC directly by using the Ethernet cable.
Figure 3-3 Network connection
3.8.Connecting Terminals
Terminals provide the RS232 and RS485 interface modes. Connect cables to the
corresponding terminals before using the interfaces. During installation, remove the
terminals from the device, unfasten the locking screws on the terminals, connect cables to
the corresponding terminals, and fasten the screws. Sort the cables in order.

4.Configuring Network Connection for a
Wireless Gateway
4.1.Connecting to the Gateway
Step 1: By default, the IP address of FE 0/1 on IG502 is 192.168.1.1; the IP address
of FE 0/2 on IG502 is 192.168.2.1. This document uses the FE 0/2 port to access
the IG502 as an example. Set the PC’s IP address to be on the same subnet with
FE 0/2.
Method 1: Enable the PC to obtain an IP address automatically (recommended)
Figure 4-1-1 Gateway Settings(1)

11
Method 2: Set a fixed IP address
Select Use the following IP address, enter an IP address (By default,any from
192.168.2.2 to 192.168.2.254), subnet mask (By default,255.255.255.0), default
gateway (By default,192.168.2.1), and DNS server address, and click OK.
Figure 4-2-2 Gateway Settings(2)

4.2.Logging in to the Gateway
Connect the PC to the gateway directly by using the network cable, start the web browser,
enter https://192.168.2.1 in the address bar, and press Enter to jump to the web login page.
Enter the user name (default: adm) and password (default: 123456), and click OK or press
Enter to access the web configuration page.
Figure 4-2 Login gateway Web management interface
4.3.Connect IG502 to Internet
Step 1: Insert the SIM card. (Note: Before inserting or removing the SIM card,
unplug the power cable; otherwise, the operation may cause data loss or damage
the IG502.) After inserting the SIM card, connect the 4G LTE antenna to the ANT
interface and power on the IG502.
Step 2: Choose Network > Network Interfaces > Cellular page of IG502 and select
Enable Cellular and click Submit.

13
When the network connection status is Connected and an IP address has been
allocated, the IG502 has been connected to the Internet with the SIM card.
