5 Installation Preparations
5.1 Preparing Cables
All cables must comply with local laws, regulations, and standards as well as
customer requirements.
The cross-sectional area of a power cable depends on the current that will
ow
through the cable and the voltage drop allowed for the cable.
The cable sizes are for reference only.

1. The size data in the table is the cable sizes applicable when the ambient temperature is
30°C (in air) and only cables in a single loop are involved.
2. When the ambient temperature is not 30°C or cables in multiple loops are routed
together, use cables with larger cross-sectional areas if the cabling distance is long.
3. Power cables should be able to withstand at least 105°C.
