Installation Planning and Design
This section provides several considerations for the DC Wallbox installation planning and design, which are to be
made by the customer to ensure a successful project.
3.1
Internet connection
ABB requires an internet connection to the DC Wallbox to conduct remote service operations including, over-
sight of the product during the warranty period, diagnosis and troubleshooting of issues, and performing soft-
ware firmware update. Not having internet connection to the DC Wallbox may severely impact, or even void, the
product warranty and/or ABB’s service level agreement (SLA).
It is the installer’s responsibility to ensure reliable internet connection to the DC Wallbox is made. Contingency
planning and the associated costs are the responsibility of the installer.
3.1.1
Internet via cellular connection
The preferred method of establishing internet connection to the charger is using the charger’s standard featured
hardware with ABB’s Charger Connect service offering, which provides internet access via Vodafone’s 4G LTE
wireless network.
In the USA, Vodafone primarily roams on the AT&T and T-Mobile 4G LTE networks. It is expected that a cellular
availability test is performed prior to construction to ensure there is reasonable signal quality to at least one of
the AT&T and T-Mobile 4G LTE bands 2 (1900 MHz), 4 (1700/2100MHz), or 12 (700 MHz).
The signal strength must be greater than -85dbm and should be measured with a cellular network signal meter,
such as a Squid-4G or Sure Call device. Handheld mobile phones are not recommended for assessing signal
strength since they are not reliable measuring devices.
The DC Wallbox only supports SIM cards provided by ABB. Customer procured SIM cards are not supported.
3.1.2
Internet via ethernet connection
Internet connection to the charger may be performed by connecting an ethernet cable to the charger from other
on-site IT infrastructure. However, due to the scope of work required for integrating this solution to ensure se-
cure communication, this method is typically not preferred.
ABB may require additional commissioning fees if ethernet cable method for establishing internet is used, de-
pending on the situation. Please contact your ABB sales representative for more details.
See sections 3.2.5 and 3.2.6 for more details on connection of conduit carrying ethernet cable and specification
of the ethernet cable.
