Installation Guide

1. Install the bolts in the holes which are circled in red in the following image below. This will make an “H-shaped” base, for the Solar Panel to be mountable on the top. The circular pipe in the middle of the shape is meant to fit over a circular shaped pole, so the whole construction sits on top with the panel facing upwards on an angle.
   NOTE
   Tighten the nuts and make sure that the rails that make up the base are holding tight against each other.

2. Mount the battery on top of the two parallel rails in the middle. Make sure it is as close as possible to the middle of the construction. Fasten it to the rails with four bolts, each having a washer and a nut. Refer to the image below on how to insert the bolts into the railing that is part of the bottom of the battery casing.
   ⚠ WARNING
   Tighten the bolts as possible as the battery is quite heavy.

3. Connect the input port power cable of the Lithium Battery to the screw terminals on the back of the Solar Panel. The image below shows the connection on the back of the solar panel.
   ⚠ WARNING
   Make sure to follow the connection in the image below as interchanging the wires would reverse the polarity. Reversing the polarity when connecting the battery is dangerous and may cause a fire.

4. The following image then shows where the cable connection between the solar panel entering the input terminal on the battery is performed in Step 3.

5. Connect the Lithium Battery output terminal cable to the input power cable of the RAK7249 – Macro Outdoor Gateway as shown in the following figure. NOTE
   Your battery life will vary depending on local illumination intensity. For a 50Ah battery and an 80W solar panel, such as the ones used in the kit, the RAK7249 – Macro Outdoor Gateway should function for about 4 days. This is the worst case scenario where there is constant heavy rain and or constant presence of clouds.
   NOTE
   If you live in an extreme condition environment that results in operational time significantly less than 4 days, reconsider increasing the battery capacity and installing a solar panel with greater power output to compensate such issues.

6. Mount the whole installation you have assembled on top of a circular pole. Put the panel facing up and insert the pole in the pipe opening on the bottom of the construction. Make sure the pole is of a sufficiently small diameter to fit with a recommended value of 65 millimeters. Use 6 pieces of M8-bolts to fix the bottom to the construction as shown in the image below.

Lightning Protection
In this document, we will be discussing how to set up your lightning surge protection system whether be your RAK7249 WisGate Edge Max situated outdoor or indoor. Such protection system must be taken into consideration to ensure a fully functional Gateway without interruption or damage from the lightings.

Outdoor Surge Protection System

Antenna Grounding
RAKwireless recommends a lightning arrestor to be installed on all the antenna N-Type terminals (LoRa, LTE, Wi-Fi and GPS). It is recommended to use a 10-AWG or better grounding wire to connect the arrestor to the tower mounted LoRa antenna. The arrestors have to be Female to Male type in order to fit the antenna and housing connectors. Make sure you use a 10 AWG or better wire to connect the screw terminals of the arrestors to the grounding rail mounted on the building wall (grounding bar in case of field deployment as in the picture).

Gateway Grounding
Additionally, it is recommended to use another 10 AWG or better grounding wire to connect the screw terminal on the bottom right side of the Gateway casing to the grounding rail (bar).
NOTE
No additional protection for the Ethernet cabling is required at the Gateway side. There is a surge protection system built-in (GDT + Anti-surge resistor).

Indoor Surge Protection
For the purpose of protecting the indoor equipment and circuitry connected to the Gateway you need to install an Ethernet port SPD lightning arrester. It should be positioned along the cabling connecting the Gateway to the PoE injector. Make sure you connect its grounding wire terminal to an appropriate building grounding point. Thus your PoE injector and network switch/router should be surge protected. Please refer to the images in the diagram below for the Outdoor and Indoor portion of the surge protection system. Should you fail to adhere to the recommendations in this document RAKwireless carries no responsibility for any damage your equipment incurs due to lightning strike!
