Direction of air flow
Please note the direction of air flow when using the following options:
• Air-conditioning unit:
The supply air enters the SICHARGE UC Dispenser from the front. The exhaust air escapes
on both sides at the top.
• Charging cable cooling (300 kW and higher):
The supply air enters the SICHARGE UC Dispenser from the front. The exhaust air escapes
on the rear.
Avoid recirculating the exhaust air for cooling.
Electrical installation
• Low voltage:
The SICHARGE UC Dispenser is designed for the connection to the low-voltage network
(230 Volt) via the SICHARGE UC charging station. Connect the SICHARGE UC Dispenser to
the SICHARGE UC charging station using a properly dimensioned supply line.
• Direct voltage:
The SICHARGE UC Dispenser is designed for the connection of direct voltage to a
SICHARGE UC charging station. Connect the SICHARGE UC Dispenser using a properly
dimensioned cable.
NOTE
Routing of DC cables to prevent radio interference
The DC charging cables from the SICHARGE UC charging station to the
SICHARGE UC Dispenser must either be buried underground or fastened directly to the
floor. We recommend using shielded cables for running the cables above ground to
reduce the electromagnetic radiation of the cables. Additional measures may be
necessary, however, in case of interferences of the radio spectrum; these include, for
example, the use of EMC filters or ferrites that must then be installed at the output of the
DC charging cable.
• Ethernet:
Connect the SICHARGE UC Dispenser and the SICHARGE UC charging station with an
Ethernet cable.
Specifications for cable routing:
– Low-voltage and DC cables must be installed shielded from the Ethernet cable.
– Separate cable routing to low-voltage and DC cables (min. 20 cm).
– Lay Ethernet cable close to grounded cabinet components.
– Ethernet cables, low-voltage and DC cables may only cross each other at a 90° angle.
– Ground the shielding of the Ethernet cable at both cable ends.
