5. Installation
The NB1601is designed for mounting on a DIN rail. Additional mounting holes allow the user to change
DIN rail adaptor orientation 90° rotated vs. default position. Please consider the safety instructions in
chapter 2 and the environmental conditions in chapter 4.3.
The following precautions must be taken before installing a NB1601 router:
– Avoid direct solar radiation
– Protect the device from humidity, steam and aggressive fluids
– Guarantee sufficient circulation of air around the device
– The device is for indoor use only
Attention: NetModule routers are not intended for the end consumer market. The
device must be installed and commissioned by a certified expert.
5.1. Installation of the Micro-SIM Card
Two Micro-SIM cards can be inserted in a NB1601 router. To install the SIM cards, you will have to
remove the SIM cover first. The SIM card connectors have a push to insert, push to eject mechanism.
So just push the SIM cards into the connector until it’s fix. The cover should be closed again afterwards.
Warning Please power off the router before inserting the SIM card.
5.2. Installation of the Cellular Antenna
For a reliable function of the NetModule router via the mobile network, the NetModule routers require
a good signal. Use suitable remote antennas with extended cables to achieve an optimal location
with a sufficient signal and to maintain the distances to other antennas (at least 20cm to each other).
The antenna manufacturer’s instructions must be observed. Keep in mind that effects caused by
Faraday cages such as large metal surfaces (elevators, machine housings, etc.), close meshed iron
constructions and others may reduce signal reception significantly.
The mounted antennas or antenna cables should be fixed with a wrench.
The following table shows how to connect the cellular antennas. 4G-LTE antennas require both the
main and auxiliary ports to be connected.
