4.2.2.1. DC output power cables
NOTICE
The cabling between the charging power unit and connected charging points must
support the maximum output current of the charging points.
NOTE
Depending on the Power Unit version, the maximum size of the wire terminal is 2 x 50
mm
2
or 2 x 150 mm
2
.
The dimensioning of the DC output power cable depends on the maximum
output current of the charging point. Multiply the output current with the
number of cabinets in the charging power unit.
The DC output power cable can be shielded or non-shielded. Non-shielded
cables must have 5 wires (2 x DC+, 2 x DC-, PE). We recommend using
copper wires.
Indicative cable types for single Satellite (300 A)
•
2 x (4 x 35 mm
2
+ PE) or 2 x (5 x 35 mm
2
)
• 4 x 50 mm
2
+ PE or 5 x 50 mm
2
Indicative cable types for double Satellites (300 A)
NOTE
Note that this is the maximum wire size that fits inside the double Satellite.
• 4 x (4 x 25 mm
2
+ PE) or 4 x (5 x 25 mm
2
)
•
2 x (4 x 50 mm
2
+ PE) or 2 x (5 x 50 mm
2
)
NOTICE
Selecting the correct cable type and size is the electrical designer's responsibility.
Obey the relevant standards, local laws, and regulations. Take into account the
specific requirements of the installation site.
See also 10: Examples of connecting output and control cables to charging
points and 11: Examples of connecting cables to the Satellites.
4.2.2.2. Control cable
The control cable is 4 x 1.5 mm
2
Cu cable If the distance between the
charging power unit and a connected charging point is up to 50 m. The
control cable is 6 x 1.5 mm
2
Cu cable if the distance is more than 50 m.
In this case, use two parallel auxiliary power wires (+24 V) and ground
wires (0 V) to compensate for voltage drop. The cable shield is grounded
at the charging power unit end.
