3. Installation
Precautions:
⚫Power supply requirements: 12V 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

6
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.

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 3-2-1-1.
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 3-2-1-1-2.

3.2.1.2. Wall Mounting (B)
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 3-2-2-1.
Figure 3-2-1-2-1 Wall mounted installation diagram
Step 3: Take out the screws (packaged with the wall mounting bracket), fasten the screws

10
in the installation positions by using the screwdriver, and pull down the device to make it
secure, as shown in Figure 3-2-2-1-2.
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.

11
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

12
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.

13
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.

14
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 3-7 Network connection
3.8. Connecting Terminals
3.8.1. Power/serial Terminals

15
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.
