Typical power cable sizes

￭
This table gives aluminum and copper cable types. The cable sizing is based on max.
9 cables laid on the cable trays side by side, three ladder type trays one on top of the
other, ambient temperature 30 °C (EN 60204-1 and IEC 60364-5-52). A correction factor
K = 0.70 is used.

Connection diagrams

￭
The following connection diagrams show how connection and grounding of the supply
modules and their switchgear can be arranged.
The switchgear and modules are typically grounded to the frame of the cabinet via
the fixing screws. If good enough electrical contact for grounding is not possible via
the fastening screws and cabinet frame, the cabinet installer must use a separate
grounding.
The diagrams show also a separate charging circuit and supply transformer. For more
information on them, see section
The connection diagrams in this section are simplified. They do not contain all details,
such as terminal markings, and are not suitable for the installation work as such. The
designer of the cabinet must:
• prepare the final circuit diagrams
• provide the final circuit diagrams to the installer(s).
The electricians that do the connections must use the final circuit diagrams.
