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,
oversight of the product during the warranty period, diagnosis and troubleshooting of issues, and perform-
ing software 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. Contin-
gency 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 fea-
tured 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 cellu-
lar 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 me-
ter, 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 secure communication, this method is typically not preferred.
ABB may require additional commissioning fees if ethernet cable method for establishing internet is used,
depending 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 specifica-
tion of the ethernet cable.

Electrical requirements
CAUTION
The installation company is responsible to design and install the electrical
installation according to the local regulations.
