Electrical wiring - cable reel
If the chiller is operated autonomously and without the use of external control components or connection to a
building management system, only a power supply for the unit must be provided.
The planning, design and execution of the type of cable/wiring and its cross-section depends on local factors
such as the type of installation, ambient temperature, installation arrangement and others. This must be car-
ried out in accordance with the applicable standards and regulations and the locally applicable technical con-
nection conditions ("TAB").
All unit-specific characteristics (power supply, maximum current consumption of the unit) can be found in the
"Technical Data" chapter of these operating instructions.
