2. Installation
2.1 Cooling
In order to achieve sufficient cooling, it is absolutely neces-
sary to leave at least 20-30cm space behind the cabinet.
2.2 Input connection of the single units
The units are delivered seperately and have to be equipped
to the cabinet during installation process.
Install the units from top to bottom, the next one directly
below the previous one, leaving no space between the
enclosures. The mains input wires are preconfigured and
accessible from the rear for every unit.

In case of a defect of one or multiple units, these have to
be removed from the cabinet. Before removal, disconnect
mains supply and DC output to load. After the replaced or
repaired units have been installed again, connect input
and DC output again.
More details about the input connection can be found in
the instruction manuals of the power supplies.
2.3 Cabinet input wiring
Grid connection is done with 5 pcs. of 4-pole wires which
are directly tied to the corresponding breaker block. This
is because the breaker blocks can only accept cables up
to 25mm². For phase mapping see the labelling inside the
cabinet.
Each breaker block supplies two units of power supplies,
counting the units from top to bottom and from 1 to 10, as
well as the breaker blocks from left to right and from 1 to 5.
Also see Figure 3 for clarification.
