ZENNER OD2 IoT Gateway Instruction Manual

ZENNER OD2 IoT Gateway

General information

Intended use
Operational safety is only guaranteed if the product is used as intended by the manufacturer. No liability is assumed for damage caused by other applications. Any modifications are only permitted with approval from the manufacturer. Otherwise the manufacturer’s declaration is invalidated.

Safety instructions
If it is necessary to establish a new power connection, the installation and commissioning must only be performed by trained qualified specialists. Only trained qualified electricians may work on electrical systems. They must be able to assess the work assigned to them at all times, detect any potential sources of danger and adopt appropriate safety measures. The installation work must only be performed in a de-energized state. Valid specifications and standards are to be observed. During assembly of the gateway, the applicable national standards are to be observed on setting up antennae systems.

Product description

Intended use

The ZENNER IoT Gateways use high-performance LoRaWAN® technology, whose excellent building penetration and long-range network coverage generally ensure the connectivity of IoT sensors even under challenging environmental and installation conditions.
The Outdoor Gateway is ideally suited for LoRa network coverage in rural and urban areas to receive values from multiple sensors. The device can be used across various sectors for a variety of IoT applications and is an integral part of ZENNER IoT system solutions. With a few gateways, entire cities can already be covered.
Due to the very robust housing made of coated aluminum, the Outdoor Gateway is very resilient to extreme weather conditions and is characterized by a high degree of reliability. In addition to the two external LoRa antennas, the ZENNER IoT Gateway Outdoor also uses an external LTE antenna to ensure the best possible connection to the backend.

Scope of delivery

The gateway is delivered in a partially assembled state. Depending on the assembly situation to be implemented, various preparations and assembly steps are necessary. Furthermore, it may be necessary to acquire additional assembly materials that are not included in the scope of delivery.

• Gateway – pre-mounted on the mounting bracket
• Mounting bracket with nuts, spring ring and washers
• 2x spacer sleeves for mounting bracket 2x 868 MHz LoRaWAN®-Antennas
• Network cable (5 m)
• Cable ties
• 2x RJ45 connector
• Equipotential bonding cable (16 mm²)
• Power cord for PoE injector

Installation location
In order to gain optimum LoRaWAN network coverage, an installation location which is as high as possible is recommended due to various technological advantages. For example, if an attic is available with potential installation space, this installation location should be preferred.
After selecting the preferred installation location, you should test the cellular network connection in this location prior to attaching it.

Mounting preparation

For power supply of the IoT Gateway Outdoor you need the PoE Injector incl. power cord.
A 5m network cable incl. RJ45 connectors and PG gland is already connected to the gateway (see ill. 6).
If the cable length is not sufficient or a network cable is already present, you can cut the mounted network cable, pull off the PG gland and use the supplied RJ45 connectors to crimp your network cable. In this case, special tools are needed. It is also recommended to perform a function test of the cable after crimping.

Installation

Pole mounting

Attach the mounting bracket incl. mounted housing to the desired pole using the u-shaped mounting hardware. To do this, you must attach the spacer sleeves to the mounting hardware and then tighten each side with a washer, spring washer, and nut.
Check that the gateway is stably attached to the pole.

Wall mounting

Check whether there are any lines running at the selected mounting location.
For wall mounting, use the 4 slotted holes (2 at the top, 2 at the bottom) on the mounting bracket.
Mark drilling holes on the wall according to the hole spacing and use a spirit level. Note the length of the network cable (range to the PoE Injector).
Drill holes, fix dowels and screws (not included, e.g. M8) in the holes.
Attach mounting bracket incl. housing to the wall. Make sure that the correct side of the mounting bracket is facing up. Please refer to ill. 3.

Electrical connection

PoE injector
Connect the power cord to the PoE Injector.
Then connect the network cable of the gateway to the “PoE” port of the PoE Injector.
If local network access should be used, the corresponding cable is to be connected to the “Data” port. If local network access is to be used, the corresponding cable must be connected to the “Data” port.

Antennas
The following illustration shows the usual arrangement and mounting positions of the antennas.
Note: The specifications of the LoRaWAN antennas differ from the LTE broadband antenna. Please take care not to mix up the antennas or connections!

Attach the antennas and make sure to tighten the lock nuts accordingly (wrench size SW19).
Now connect the antennas with the antenna cables and the connectors on the housing using the following connection layout.

You can additionally fasten the antenna cables to the mounting bracket with cable ties.
The antennas are mounted identically for all variants us- ing the supplied lock rings and serrated lock washers. All antennas are connected to the gateway with the enclosed N-connection cables.

Equipotential bonding cable
The potential equalization cable (ground cable, 16 mm²) must be connected to the mounting support and a bonding rail.

Note: Attaching the Equipotential bonding cable to a lightning rod is not permitted.
