Hardware Installation

3.1 SIM Card Installation

1. Take the SIM cover down, and use an ejector tool to open the SIM card tray. Insert the nano (4FF) SIM card, then put the slot with the SIM card back into the device.
2. Rotate back the cover and tighten it with a wrench to prevent water from entering the device.

3.2 Power Supply
SG50 can be powered by either a 12-24 VDC external supply or a solar panel. In the meantime, the internal battery pack will also be charged. When the external supply is disconnected or there is not enough power for the solar panel, SG50 can be powered by the internal battery pack.

Battery Installation

1. Release the fixing screw on the side of the device, and remove the battery compartment cover.
2. Push the battery into the battery compartment as the icon shows. If you need to take out the battery, hold on the latches on the battery to pull it out.
3. Fix the cover back to the device using the fixing screw.

Note：

• After installing the battery, the device will not power on automatically. Please connect the power cable of the solar panel to the device to turn it on. When the power cable is disconnected, the device will power off.
• The device can not be charged when its temperature is more than 50°C. Please avoid direct exposure of the device to sunlight.
• When the device detects the temperature is lower than 0°C and solar panel power is enough (more than 7W), the device will heat the battery until the temperature reaches to 10°C, then charge the battery if the battery level is not full.
• The battery should be removed from the device if it will not be used for an extended period.

3.3 Gateway Installation
SG50 with solar panel can be mounted either to a wall or pole. It is suggested to install the device on sunny days for solar panel adjustment and charging.

3.3.1 Mounting Bracket Installation
Wall Mounting:
Drill 4 holes on the wall according to the mounting bracket and insert the wall plugs into these holes. Then fix the mounting bracket to the wall by fixing the wall mounting screws into the wall plugs. Pole Mounting:
Straighten the hose clamps and slide them through the rectangular rings in the mounting bracket. Wrap the hose clamps around the pole, then use a screwdriver to tighten the locking mechanism by turning it clockwise.

3.3.2 Solar Panel Installation

1. Fix the solar panel to the solar panel bracket using 6 fixing screws.
2. Hang the solar panel bracket onto the mounting bracket and fix both parts using 2 fixing screws first. Adjust the angle of the solar panel bracket (15°, 45°, and 75° is optional) based on the installation environment. Then fix the remaining two screws to the solar panel bracket.

3.3.3 Device Installation

1. Fix the device to the opposite side of the solar panel bracket using 4 screws. When installation, it is suggested to fix the 2 screws on the top at first.
2. Install antennas as Antenna Installation chapter.
3. Connect M12 power cable of the solar panel to DC power connector of the device, then the device will power on automatically.

3.3.4 Antenna Installation
U-strap Mounting:

1. Pass the LoRaWAN® antenna through the U-strap clamp and fix the U-strap clamp to the side of the mounting bracket using 2 flat washers and 2 screws.
2. Connect one end of the antenna coaxial cable to the LoRaWAN® antenna, the opposite end to the device’s antenna connector.

U-bolt Mounting:

1. Pass the LoRaWAN® antenna through the antenna clamp and fix it using 4 screws, then wrap the U-bolt around the pole and fix the clamp with nuts and other accessories.
2. Connect one end of the antenna coaxial cable to the LoRaWAN® antenna, the opposite end to the device’s antenna connector.
