Lightning protection
It is important to follow closely the guidelines that are described in this section, in order to minimize risk of
damage on Velos systems in case of lightning. Nedap does, however, not accept any responsibility for damage
caused by high voltage (such as lightning), as described in the Warranty Policy.
Protective Earth (PE)
PE is meant for safety related issues such as electric shocks to humans or animals. PE will not protect devices
(sufficiently) when they are struck by lightning. Normally PE is situated next to the main power source only.
Grounding
Grounding is a connection to the ground, but not Protective Earth, for example a metal roof that is connected to
different earth electrodes in order to lead high peak currents (such as lightning) to the earth.
3.1.2 Network requirements
Basic network requirements
• Router to connect the VPU (VP8002) to the Internet.
• Use of DHCP (Dynamic Host Configuration Protocol) advised.
• LAN Ethernet cable UTP minimum cat 5.
• Minimum upload speed: 1 MB/s
Wi-Fi requirements
To experience all the benefits of the Nedap system, a full covering Wi-Fi installation is crucial in the area
where the system is applied. A functional Wi-Fi connection offers easy access to the mobile interface, allowing
operation by smartphone or tablet. Because of the wide variation in barn designs, we recommend to make use of
local Wi-Fi specialists to plan, install and service such a Wi-Fi installation.
In order to install single wireless networks, we advise you to consider the following conditions. These conditions
are set up for a so-called single wireless network.
General recommendations regarding setting up a Wi-Fi installation
• Always follow local circumstances and legislation regarding wireless network configurations.
• Never use powerful Wi-Fi transmitters; powerful transmitters will generate more noise.
• Do not use dual band or the 5 GHz band; only use the 2,4 GHz band.
• Never use (multiple) ordinary consumer electronics Wi-Fi routers.
• Only use professional access points to create a wireless network.
• Only use a single wireless network configuration, also called "roaming network".
• Use splash and dust proof plastic housings (IP65) to install professional access points.
Wi-Fi bridge requirements for point-to-point connection
• 5GHz to minimize interference (recommended 5.18GHz ~ 5.825GHz).
• High-Power Output to ensure long distance coverage.
• Connection rate of 300 Mbps or higher.
• Internal High-Gain Directional Antenna (10 dBi to 13 dBi or higher).
• Supports WPA2 Wi-Fi Security.
Nedap can never be kept responsible for incorrect functioning of networks or any damage arising from the
recommendations mentioned in this document.
3.1.3 Electromagnetic requirements
Nedap Animal Identification uses radio waves in compliance with ISO 11784/11785 standard and local
regulations.
