All wires for 3-phase and 1-phase variants of the DC Wallbox may connect directly to the ABB provided termi-
nals, with exception to the protective earth wire for the 3-phase variant DC Wallbox. The protective earth wire
for the 3-phase variant DC Wallbox requires for the installer to crimp a terminal onto it using the terminal manu-
facturer’s recommended crimp procedure and tool.
The integrity of the electrical grounding is essential. Ensure that the equipment grounding terminal is used in
the device and an actual grounding conductor is installed to provide a path back to the source upstream panel.
(Do not use the conduit or raceway as the sole equipment grounding conductor).
3.2.5 Conduit for ethernet cable
The DC Wallbox does not have a hole designated for a conduit carrying only an ethernet cable to connect to. If
ethernet cable solution is required for an installation, please contact your ABB sales contact person to review
ethernet cable entry solutions.
3.2.6 Specification for ethernet cable
If the cellular connection is not available, ethernet connection must be made to the charger using a shielded
8P+PE ethernet cable with RJ45 connectors. Additional recommendations include:
•
Maintain distance of 75 meters or less. Distances over 75 meters require a custom engineered solution.
•
Minimum bandwidth:
upload: 128 kb/s
download: 4 Mb/s
•
99.9% availability
•
600V rated cable that may route beside input power wires for short distances
3.3 DC Wallbox placement
Placement of the Terra DC Wallbox must be carefully determined by accounting for charging cable reach, DC
Wallbox position with respect to parking space, bollards and wheel stops, ventilation and working clearances,
and other local codes and regulations (e.g. ADA requirements in the USA).
3.3.1 Charging cable reach
The Terra DC Wallbox charging cables are available in lengths of 3.5 or 7 meters. The charging cables exit the
charger enclosure on both the right and left sides. The cables and the connectors mounted on the cables are dif-
ferent depending on the charging standard and vary in flexibility.
The figure below shows an example of a dual connector charger with both types of connector and the corre-
sponding reach area. The green circle with a continuous line describes the CHAdeMO cable 3.5m and the red
circle with a continuous line describes the CCS cable 3.5m. The broken lines indicate the same cable types with a
length of 7 meters (23 ft).
