Internet And Network Requirements - ZAPTEC Pro Installationsanleitung

Make sure that the installation is designed for maximum and minimum short-circuit current. The fitter is responsible
i
for calculating and designing the installation infrastructure so that it is compliant with the requirements of NEK
400.
ZAPTEC always recommends installation of the charging stations with all three phases where available. This
i
ensures that the balance between load and phase is dynamic and makes it possible to use all available energy in
the installation and between the charging stations.

Internet and network requirements

Protocols
4G, WiFi 2.4 GHz, IEEE 802.1 1 b/g/n (static channels 1–1 1)
Minimum signal strength per charging station: –75 dBm
DHCP server with a sufficient number of IP addresses – one for every device connected
The anticipated data traffic for every ZAPTEC Pro is around 3 MB a day.
Network security
All traffic and communication between the charging stations and the cloud solution is
encrypted. All of the following network services are required to allow ZAPTEC Pro to
work together with ZAPTEC Portal. All the ports stated are outgoing ports, and you
have to open them in active firewalls. ZAPTEC Pro links to the necessary services without
opening incoming ports, even if they are located behind a NAT.
MQTT
TCP port 8883: zapcloud.azure-devices.net
A connection to Azure IoT Hub, which uses MQTT over TLS, acts as a primary
communication channel between ZAPTEC Pro and ZAPTEC Portal. The condition of the
charger is transmitted to ZAPTEC Portal, and it receives control commands such as start/
stop charging. Communication is encrypted using TLS v1.2, and the server certificate is
verified by ZAPTEC Pro. When it is connected, the server verifies the charger by means
of a unique password that is generated during production. More information on Azure
IoT Hub can be found here: https://docs.microsoft.com/en-us/azure/iot-hub/about-
iot-hub
HTTPS
TCP port 443 (multiple domains)
ZAPTEC Pro connects to ZAPTEC Portal by means of HTTPS in order to download
firmware updates. This communication is encrypted. ZAPTEC Pro verifies the server
certificate before the update is download, and the firmware update itself is verified
cryptographically before being installed.
The following domains are used during firmware updates:
- zapcloud-api.azurewebsites.net
- devices.zaptec.com
- api.zaptec.com
